She has worked as a conservator and undertaken resin research at the Art Institute of Chicago, J. Paul Getty Museum and the National Gallery of Art. She treated a collection of paintings by Frederic Remington at the Museum of Fine Arts, Houston. Since 1993 she has been lecturing and teaching workshops on resins for varnishing and retouching in North and South America and Europe.
Robert Proctor has a Bachelor of Arts in Art History from Tulane University in New Orleans and a Master of Arts and Certificate of Conservation from Buffalo State College. He trained in Munich at the Bayerisches Nationalmuseum, worked at the Saint Louis Art Museum, Indianapolis Museum of Art and Museum of Fine Arts, Houston. In addition to workshops on varnishes, Rob is a specialist in the reweaving of tears and has taught workshops on reweaving. He has worked as a contract conservator and treated a number of public murals.

Overview
Many different materials have been used for varnishing and retouching. Traditionally, natural resins were primarily used for this purpose. In the 20th century synthetic polymers were introduced. These are often chemically and physically more stable than their natural counterparts. The optical properties of varnishes are however largely controlled by their molecular weight. By using synthetic low molecular weight resins for varnishing and retouching, an appearance similar to that obtained using natural resins can be achieved. Factors affecting stability and appearance, as well as application methods and solvents suitable for these new resins, will be discussed.
The workshop will focus on synthetic low molecular weight resins and how they differ from polymers and dammar. Participants will use practical sessions to evaluate the properties of resins used as varnishes in terms of their application and appearance. Through these practical sessions and demonstrations, participants will establish how the choice of resin, solvent or stabiliser will affect the properties of the varnish not only on application but subsequently upon ageing. Participants will leave the master class with an individual canvas board (60x80cm) on which at least 15 varnish recipes have been tested.

Lectures will cover:

  • Function of varnishes
  • Chemical properties of resins and their degradation
  • Factors affecting optical characteristics of varnishes
  • Effects of stabilisers
  • Retouching media
  • Criteria for choosing appropriate varnishes
  • Varnish application techniques
  • Solvent selection: polarity, solvent strength and evaporation rates

Materials:
Varnishes and artist canvas boards will be provided. Participants are encouraged to bring their favourite brush for applying varnish.


Workshop fees:
€ 825.00
Workshop fees will include lunches.
Deadline for registration: 1 February 2018

Bosch Research and Conservation Project wint EU Prijs voor Cultureel Erfgoed / Europa Nostra Prijs 2017

Het Bosch Research and Conservation Project is uitgeroepen tot winnaar van de EU Prijs. Voor het hele
persbericht, zie de speciale Radboud Universiteit webpagina.

De prijs, gelanceerd door de Europese Commissie en georganiseerd door Europa Nostra, viert en promoot succesverhalen met betrekking tot het beheer en behoud van erfgoed, onderzoek, onderwijs en communicatie, en door de kracht van hun voorbeeld stimuleren we creativiteit en innovatie. Op deze manier draagt het bij aan een sterkere publieke erkenning van cultureel erfgoed als een strategische hulpbron voor de Europese samenleving en economie.

In 2016 was het 500 jaar geleden dat de wereldberoemde schilder Jheronimus Bosch overleed, een kunstenaar wiens leven en werk grenzen en taalbarrières overbrugde. Zijn roem verspreidde zich al snel over heel Europa, en zijn bizarre en uiterst creatieve beeldspraak werd, en wordt nog steeds, ook ver buiten Nederlandse grenzen zeer bewonderd. Zijn bewaard gebleven oeuvre bestaat nu uit ongeveer 24 schilderijen en 21 tekeningen, en is te vinden in 26 verschillende musea en particuliere collecties in 10 verschillende landen, waarvan 9 in Europa.

Het ‘Bosch Research and Conservation Project’ (BRCP) werd in 2007 voor het eerst als initiatief gepresenteerd en nu, tien jaar later, heeft het BRCP-team de resultaten gepresenteerd van het omvangrijkste internationale onderzoek dat ooit naar de schilderijen en tekeningen van Jheronimus Bosch is ondernomen.

In zeven jaar van toegewijd onderzoek, ontdekte het team een schat aan nieuwe informatie over de kunstenaar en zijn overgebleven werk, wat is gepubliceerd in de tweedelige monografie Jheronimus Bosch, Schilder en Tekenaar: Catalogue Raisonné (verschenen in NL, EN, FR, DU) en Hieronymus Bosch, Painter and Draughtsman: Technical Studies, en ook toegankelijk is via de innovatieve website boschproject.org. In het Boschjaar en de aanloop ernaar vonden niet minder dan elf restauraties en twee spectaculaire en belangrijke tentoonstellingen in 's-Hertogenbosch en Madrid plaats, die bezocht werden door ruim een miljoen mensen.

“Dit project vertegenwoordigt innovaties op het gebied van onderzoek, restauratie en technologie en is een uitstekend voorbeeld van de verbinding tussen onderzoek en behoud van kunst,” aldus de jury.

Het Bosch Research and Conservation Project (BRCP) is een ambitieus, grootschalig internationaal onderzoeksproject, opgezet door de Stichting Jheronimus Bosch 500, Het Noordbrabants Museum en de Radboud Universiteit.

“Het hele proces van dit project is buitengewoon. De inspanningen van de verschillende belanghebbenden in de publieke sector om alle betrokken partijen te mobiliseren om zo’n voortreffelijk resultaat te leveren, waaronder een internationale tentoonstelling en een brede verspreiding van de resultaten, is geweldig. Het relatief klein team heeft duidelijk met toewijding gewerkt en met een scherp inzicht in de historische, culturele en sociale context van Bosch”, benadrukt de jury.

In heel Europa zijn er 29 laureaten. Tijdens de prijsuitreiking in Turku (Finland) op 15 mei, zullen de zeven Grand Prix laureaten en de winnaar van de Publieksprijs bekend worden gemaakt. Stem voor BRCP op vote.europanostra.org en ontdek boschproject.org.

Solvent Workshop – 15th -17th February – National Museum, Stockholm, Sweden, Gwendoline R. Fife ‘Modelling solvent behaviour, solvent effects on paint films, and the practical ramifications’

Quotes from participants:

'We enjoyed every minute of the workshop and the lectures and found them inspiring and rewarding' Troels Filtenborg, Senior Painting Conservator, National Gallery of Denmark
‘So much learning and so much fun!’ Malin Borin, Konservator/Conservator, Göteborgs konstmuseum, Göteborg Sweden
‘Fantastic workshop’ Loa Ludvigsen Painting Conservator, National Gallery of Denmark
'Very inspiring and motivating’ Krister Eliasson Painting Conservator, SSM

Held at the painting conservation studios of the National Museum in Stockholm, Sweden, the aim of the workshop was to support practitioners in their practical applications of solvents. The results of investigations into the effects of organic solvents on artist paint films are potentially highly beneficial in developing our conceptual modeling and understanding of paint films, and the possible negative effects from solvents. However, applying these theoretical findings to practice can be challenging. From a conservator’s perspective, examining how the magnitude of these solvent effects can be influenced by our solvent choice, techniques and practices is a pertinent focus, and was the central tenet of the workshop.

The workshop provided the following lecture components:

  • The fundamentals of organic solvents and the published models used for describing solvent behavior.
    • Research findings regarding organic solvent effects on paint films.
    • Recent findings regarding the ramifications: can these effects be influenced by adaptations in our solvent use?

These were followed by discussions covering experiences and opinions regarding solvent choices and application, with practicals in solvent selection and application in varnish removal testing on museum paintings.

Many thanks are extended to the organisers and all the participants for their interest and enthusiasm!

 

Conference on Vandalism & Art, June 8-9 2017 Maastricht, The Netherlands

Vandalism & Art

Vandalisme’, a term coined in 1794 by Henri Gregoire, now relates in the public consciousness to the intentional damage to public heritage. It is an ever present risk for art displayed in public venues. Acts of vandalism are often instigated by political causes, religious beliefs, psychological motivation or public unawareness. Cultural heritage managers have to deal immediately, under scrutiny, with the visually intrusive effects whenever these acts take place.

No matter the cause, the act itself results in damage to the work of art. The means of the act may be varied but the effects can be both structurally and aesthetically devastating. The means may be intentional: knife attack, acid attack, spray paint application, hammer attack, throwing paint and graffiti against sculptures and on monuments. But also carried out without consideration: chewing gum stuck on the eyes (of sculpture), scratched personal names into stone building, accidental pen marks. The public’s disregard for public heritage increases as a result of these manifestations of damage, which in turn can instigate further damage.
Restoration of vandalised works of art can be costly and time consuming. Treatment asks for the development of unconventional or ground breaking techniques and materials. The immediate response of social media to acts of vandalism is a new phenomenon that requires prompt managing; thus, pushing conservation into new fields of communication.
The decision-making on what to do may differ if the vandalism has taken place in public space or inside a museum: should the damage be left visible as a historical record or should the object be returned to its original appearance? The intent of the offence may be recognised as valuable demonstration of public outcry, or even an artwork in itself, and therefore saved. How do the various stakeholders deal with vandalism? How to react in the first instance? Who is the appropriate stakeholder to make decisions on what to do? What are the legal and economic consequences of these acts?
This two day conference will allow all stakeholders to share their experiences, exchange ideas and define new polices when dealing with acts of vandalism. Decisions made when treating vandalised art works will be debated through case studies and new protocols for dealing with public awareness and management of social media will be addressed. Legal and economic issues and implications will be debated.

Additional information

Beyond climate control there are two powerful and affordable tools for the preventive conservation of panel paintings: framing and microclimate enclosures. Framing can directly affect the stability of a painting; it should be carefully selected and executed to perform properly during transport, exhibition, storage, and in the event of climate fluctuations. The microclimate enclosure is a method to prevent damage related to fluctuations of relative humidity and is often chosen to protect artworks in transit or sensitive paintings facing poor climate conditions.

Content of the Workshop
The workshop will review the history, evolution and current trends in framing and microclimate enclosures for panel paintings. These techniques can be extrapolated to other climate-sensitive artworks on paper, board or canvas. The workshop is structured in theoretical and practical sessions.
During the practical sessions the participants will build their own microclimate enclosures: two microclimate frames and a MarvelSeal envelope, a representation of the main three techniques used today. All materials are included in the registration fee and the participant will keep their mock-ups.
The workshop is designed for all the actors involved in the care, exhibition and loan of paintings. Conservators and depot managers in charge of framing and making microclimate enclosures will learn the strategies and practical skills to offer the most suitable solution in a case-by-case basis. Collection managers and registrars are encouraged to join the workshop as well, since they are active actors in the decision-making process regarding the care, exhibition and transport of the artwork and often follow them on loan.
The workshop will equip all participants with a solid background on current museum practices.

Review of Wood Science and Technology II: Microclimates for Panel Paintings

The two day conference - 11 speakers, three posters and three sponsor presentations - were attended by a 110 delegates from over 19 different countries. Sponsoring for this event included Tru Vue, Meyvaert, Proppagroup and our near neighbours the Bonnefanten Museum.
The content of the presentations, posters and contribution by our sponsors, was outstanding. Each of the speakers discussed ‘microclimates’ in relation to protective enclosures for art objects, and perhaps each of you had a slightly different meaning for the terms ‘microclimate’ and ‘enclosure’. Microclimates can be used to describe either local environment ‘trapped’ in a small (or large) enclosed space, or the environment in the vicinity of the object that is manipulated to achieve certain set-points. Some of you even discussed a building as a microclimate environment. Monitoring of the former smaller space can be more accurate than the latter due to the smaller volumes involved and the accuracy of the ‘point' measuring equipment. Different terms : ‘showcase’, ‘vitrine', ‘cabinet’, ‘shadowbox’, ‘box’, ‘frame’, ‘envelope’ etc were used interchangeably and with different meanings. I suggest that we clearly define these systems and give standard names (as much as this can be done) to each system in order that communication with those in affiliated fields (engineering, climate control, curatorial, etc) can be facilitated. 
 
This will help those in decision-making roles discuss the needs and possibilities for individual art works, especially panel paintings, the individual needs of which should not be standardised. New tools for measuring, calculating and monitoring microclimate enclosures are now available for the field - HERIe and WUFI. Care must be given equally to the aesthetics, science and practice of designing a microclimate enclosure. And historical frames should be respected as part of the original structure and not as a sacrificial element that can be manipulated to suit the needs of the painting. 
 
As maintenance and durability of the microclimate enclosure is key, it seems that microclimate enclosures should be seen as temporary solutions for moments where the panel painting has the potential to be exposed to undesired climate conditions. The idea of temporary microclimate envelopes, frames or shadowboxes for short term display (and travel) seemed to be the ideal solution. Leakage of the microclimate is inevitable but can be mitigated and, given a stable external environment, is minimal in the short term. Opening microclimate enclosures is dangerous without adequate instruction and this aspect should be considered for traveling art works or when reconditioning microclimate enclosures. 
 
Microclimates enclosures seem to be viable green solutions to controlling the climate of larger spaces and this helps in a time of increasing loans and movement of fragile sensitive art works. The microclimate enclosure should not be seen as a long term solution that needs no maintenance and museums implementing these enclosures as part of collection care policy should be well aware of the disadvantages as well as the advantages of housing their collection in such a manner. And these aspects must be communicated to those making policy decisions.
 
The scientific committee, consisting of Roger Groves, Sara Mateu, Luuk Hoogstede and Kate Seymoure will compile postprints including
  • extended abstracts of the presentations;
  • a comprehensive literature list (with links to available papers);
  • a list of materials, tools, equipment used for making microclimate enclosures and supplier list;
  • a list of techniques for monitoring and maintaining a set microclimate;
  • pdf versions of powerpoints (password protected)
  • schematic designs of available systems.
This would be intended as a useful resource and educational tool providing a digital ‘manual’ or ‘guide’ to microclimate enclosures for panel paintings.

 

Start werkzaamheden Horecaboulevard Centraal Station Amsterdam

Het door architect Pierre Cuypers ontworpen Station Amsterdam Centraal ging open in 1889. Sindsdien is het stationsgebouw vaak aangepast, er werden tussenvloeren geplaatst en ruimtes toegevoegd. Ornamenten en schilderingen werden weggehaald of verdwenen achter stucwerk, tegels of een verlaagd plafond. Hierdoor werd Cuypers’ oorspronkelijke gebouw steeds minder zichtbaar.

In juni 2016 zijn restauratiewerksamheden begonnen om de oorspronkelijke onderdelen weer zichtbaar te maken. De oorspronkelijke gangen tussen de horecagelegenheden worden teruggebracht in hun originele staat. Dit gebeurt door aannemer Kondor Wessels, BOAG Advies en Management, Venema Restauratie, Stichting Restauratie AtelierLimburg (SRAL) en Van Wijk Houtindustrie. De werkzaamheden vinden plaats onder leiding van Johan Venema en SRAL’s Claudia Junge. “Ons werk is een combinatie van restauratie en reconstructie”, legt Johan uit. “Soms is restaureren simpelweg niet mogelijk, omdat onderdelen zijn weggehaald. Dan moeten we reconstrueren. Tak Architecten heeft een nieuw ontwerp gemaakt voor de historische onderdelen van het station, in de stijl van Cuypers, en op basis daarvan werken wij nu. Mijn aandachtsgebied is vooral het slopen en restaureren van de stenen onderdelen, dat van Claudia is het schilderwerk, en Van Wijk Houtindustrie reconstrueertkozijnen en lambriseringen.”

Lambertuskerk te Neeritter afgerond

Na een maandenlange restauratie zijn het Lucia en Maria altaar uit de St. Lambertuskerk te Neeritter weer in ere hersteld. De beide altaren dateren van rond 1700 en zijn in de 19de eeuw overgeschilderd met een decoratief grijs, blauw en rood imitatiemarmer. Vele jaren stonden de altaren in slechte staat in de kerk, verf bladderde van de houten ondergrond en het houtwerk was hier en daar flink door houtworm aangetast en het Lucia altaar was verzakt. De beide antependium, beelden, engelenborden en altaren zijn gerestaureerd door medewerkers van SRAL terwijl het timmerwerk werd uitgevoerd door Timmerbedrijf van den Heuvel uit Neeritter.

Restauratie plafondschildering in Kasteel Arcen

In de kasteeltuinen in Arcen wordt momenteel een plafondschildering gerestaureerd. De 18 e eeuwse schildering, voorstellend de Romeinse godin Flora, verkeert in een slechte staat. De schildering is erg vervuild en bedekt met een sterk gecrepeerde en vergeelde vernislaag. De vernislaag is oorspronkelijk niet bedoeld; een glanzende laag zal immers de perceptie van de voostelling sterk hinderen. De schildering is aangebracht op een kalkpleisterlaag. De verflagen schilferen af tot op deze pleisterlaag. Verder zijn er gerepareerde scheuren zichtbaar. De loslatende verflagen en scheuren in het plafond blijken al langer een probleem, te zien aan de vroegere behandelingen om deze te zekeren. Destijds zijn er honderden gaatjes geboord om vervolgens vol te spuiten met een consolidatiemiddel. De scheuren zijn toen uitgevuld met betonmortel. Deze kleine gaatjes, gevulde scheuren samen met de weggevallen verf , vervuiling en vergeling van de schildering storen de optische illusionaire werking enorm. Aan de hand van een eerder uitgevoerde proefrestauratie wordt de schildering momenteel geconsolideerd en schoongemaakt. Dit is een lastige en arbeidsintensieve ’klus’ omdat door de aanwezigheid van de verouderde vernis het vastzetten van de verf bemoeilijkt wordt. De behandelingsmethodiek is dan ook speciaal voor dit plafond aangepast. Na het vastzetten van de verflagen zal de vernislaag afgenomen worden met gel tissues. De gaatjes en andere oneffenheden zullen daarna gevuld worden. Vervolgens zullen alle storende delen geretoucheerd worden om er weer een leesbaar geheel van te maken. Hierdoor zal de kleurwerking en de bedoelde ruimtelijke illusie weer volledig tot zijn recht komen.

Conservation and restoration treatment of 'De Lakenmarkt'

The largest Bosch retrospective ever : Jheronimus Bosch – Visions of a Genius opens at the Noordbrabants Museum, in the artist’s home town of s-Hertogenbosch (13th February until 8th May). To be viewed in this exhibition, The Noordbrabants Museum well-known and beloved work ‘De Lakenmarkt’ recently underwent major conservation and restoration at the research and conservation centre, SRAL, in Maastricht (photo 1). For many years prior to this treatment the painting had been covered in thick non-original overpaints
(photo 2). Photo 3 (after removal of varnish and overpaints) shows the considerable losses to the original layers that had previously occurred. These losses were reintegrated with a considered  and courageous approach involving significant reconstruction (Photo 4).Hence ‘De Lakenmarkt’ -which features Bosch’s house in the 16th century – can be displayed as part of this major exhibition.

In addition to workshops on varnishes, Rob is a specialist in the reweaving of tears and has taught workshops on reweaving. He has worked as a contract conservator and treated a number of public murals.

Overview
Many different materials have been used for varnishing and retouching. Traditionally, natural resins were primarily used for this purpose. In the 20th century synthetic polymers were introduced. These are often chemically and physically more stable than their natural counterparts. The optical properties of varnishes are however largely controlled by their molecular weight. By using synthetic low molecular weight resins for varnishing and retouching, an appearance similar to that obtained using natural resins can be achieved. Factors affecting stability and appearance, as well as application methods and solvents suitable for these new resins, will be discussed.

Workshop:
The workshop will focus on synthetic low molecular weight resins and how they differ from polymers and dammar.  Participants will use practical sessions to evaluate the properties of resins used as varnishes in terms of their application and appearance. Through these practical sessions and demonstrations, participants will establish how the choice of resin, solvent or stabilizer will affect the properties of the varnish not only on application but subsequently upon ageing. Participants will leave the master class with an individual canvas board (60x80cm) on which at least 15 varnish recipes have been tested.

Lectures will cover: 

  • Function of varnishes
  • Chemical properties of resins and their degradation
  • Factors affecting optical characteristics of varnishes
  • Effects of stabilizers
  • Retouching media
  • Criteria for choosing appropriate varnishes
  • Varnish application techniques
  • Solvent selection: polarity, solvent strength and evaporation rates

Materials:
Varnishes and artist canvas boards will be provided.
Participants are encouraged to bring their favourite brush for applying varnish.

Workshop fees:
Standard: € 775,00                                              
Deadline for registration May 1st 2016

Conference on Wood Science and Technology II: Microclimates for Panel Paintings, 20-21 October 2016

This two day conference on microclimates for panel paintings is directed towards the latest developments in this field. Microclimate boxes are considered best practice for moisture sensitive objects for exhibition in uncontrolled environments or travelling. It is necessary to control climate conditions (relative humidity and temperature) in order to prevent unnecessary stresses developing in the object as the hydroscopic materials absorb or desorb moisture content. To achieve this the microclimate environment needs to be maintained to set parameters. This is best attained in air-tight enclosures, either encapsulating the artwork or incorporated in the original setting, such as the frame. Research has shown that the air surrounding the artwork should be kept to a minimum and that materials used for constructing the enclosure should be carefully selected. Debate is ongoing if the interior climate requires buffering or not. The last major review of innovations in the field was held in Copenhagen in 2007 and further research was reported in the outcome of the EU funded PROPAINT project (2010). This Conference will provide an opportunity for those constructing and designing microclimate enclosures to report their latest experiences to conservators and museum curators. Furthermore, sessions focusing on the science behind microclimate enclosures will be scheduled.

Project consultation and workshop in Tallinn

An exciting conservation project has just commenced on the Passion Altarpiece (c.1515-1520) at the Niguliste Museum in Tallinn, Estonia. The history of this art work is complex, and the outer wings have been variously attributed to Michel Sittow (c. 1469 – 1525) – an internationally appreciated court artist who originated from Tallinn (Reval). These wings have been requested for the upcoming exhibition of this important artist’s work which will take place at the National Gallery in Washington D.C. and at the KUMU Art Museum (Art Museum of Estonia) in Tallinn, in 2018.
Gwendoline R. Fife from SRAL was invited by the Art Museum of Estonia, and the Academy of Art in Tallinn  to discuss and determine an appropriate conservation methodology for treating the paintings in collaboration with the head conservator for the project Hilkka Hiiop, and assistant Johanna Lamp, and art historian Greta Koppel. Two days were spent on the objects examining and testing different approaches for removing the varnishes and overpaints. Subsequently Gwen gave a 3 day series of lectures with practical workshop elements regarding organic solvents. The fundamentals of organic solvents, the modelling of their behaviour, research into their effects on paint films, and findings regarding application techniques, were reviewed and discussed. The conservation students and practitioners reacted very enthusiastically to understanding and discussing more about these important topics, resulting in an enjoyable and fruitful workshop for all.

Portable X-Ray Fluorescence Spectroscopy Conference and Workshop, July 9-10, 2015

This two day meeting of lectures and accompanying demonstrations aims to highlight the possibilities and limitations of pXRF so that strong collaborations between conservators and conservation scientists can ensue. Emphasis on interpretation of acquired data from pXRF analysis will be given.

Portable X-Ray Fluorescence Spectrometry (handheld and macro): friend or foe?

The analysis of painting materials relies more and more on pXRF for the determination of inorg anic pigments. Because pXRF is nondestructive, and has become more available to conservators due to price and accessibility, these instruments have been utilised with rapidly increasing frequency. Results seem immediate and conclusive. The technique has thus become a dominant tool in the determination of pigments in recent years. But as conservators who have become more acquainted with the technique will tell you, performing analyses using pXRF equipment on complex paintings is not quite as simple as point and shoot. Interpreting the data is key. What are the benefits and pitfalls in examining paintings with pXRF. How can these be enhanced or overcome?

Programme

The two day conference and workshop aims to give participants an understanding of the principles of
pXRF and the instrumentation available. Participants will leave with an understanding of the complexities of this system and be comfortable in a dialogue with scientists carrying out research in this area. The purpose is to encourage investigation and research using this technique and provide tips on how to make the most of data deriving from examination. Lectures given in the morning sessions will focus on theoretical concepts of chemistry and physics necessary to understand the principles of pXRF. Overviews of instrumentation that are available and accessible in the field will be given. Case studies and experiences of pXRF investigations by conservators will also be part of the programme. Experts in pXRF investigation will present recent projects and possibilities. Afternoon sessions will consist of demonstrations of instrumentation by experienced operatives. A number
of different instrumentation will be available provided by the leading supplier of instrumentation and invited speakers. Break away sessions during which some limited hands-on investigation will be carried out. The size of the groups will be determined by the number of participants.

MACCH Kick-Off Conference 2015

Assembling Value: The changing roles of experts and expertise in art and heritage worlds
Sunday 22 - Monday 23 March 2015, Maastricht
The conference coincides with the launch of the Maastricht Centre for Arts and Culture, Conservation and Heritage (MACCH). MACCH is a joint initiative of four faculties of Maastricht University, the Stichting Restauratie Atelier Limburg (SRAL) and the Study and Documentation Center for History of Limburg (SHCL). This interdisciplinary research platform brings together scholars and professionals working on the intersecting fields of arts, culture and heritage, the national and international legal framework concerning these areas and the financial developments of the international art market. By combining legal, historical, philosophical and economic expertise, and by working across the traditional boundaries that separate academic and professional disciplines and institutions, MACCH meets the demands of the increasingly multi-layered and complex challenges facing the fields of arts, culture, conservation and heritage today. Focus areas of research and teaching include the changing role of experts and expert knowledge, public participation, and technological mediation.

Restoration of the vaulted ceiling paintings in the city hall Maastricht

Currently, a part of the painted ceiling in the main hall of the 17th century city hall in Maastricht is undergoing conservation and restoration. The vaulted ceiling is situated directly above the main entrance and is part of an ensemble further consisting of a cross vault and a cupola. The painted decorations were carried out between 1667 and 1671 by Theodoor van de Schuer. It is of particular interest that the paintings are executed on plaster and not – as was more common at that time – on wooden planks. Van der Schuer was an interior painter of some reputation: he was in charge of the ceiling paintings in the so-called Trêveszaal  of het Binnenhof in The Hague (Dutch parliament buildings).
Before restoration commenced,  the condition, materials and techniques as well as the restoration history were thoroughly examined and documented. Based hereupon, a plan of action was formulated. One crucial part of this preliminary examination was the unravelling of three invasive restorations: the first one carried out in 1838 by Theodoor Schaepkens, followed by two other interventions, one in 1895 through the Belgian painter Vidar and one in 1951 by Prof. Thé Lau en Alphons Volders.
The complexity of the treatment demands a close interaction of the various specializations within SRAL. The knowledge and experience of the paintings conservator is necessary to tackle the removal of varnish and various layers of overpaint. Stratigraphic windows, paint cross sections, examinations with ultra violet light and instrumental analysis are employed to identify the overpaints. The fact that the paintings are carried out on plaster asks for the expertise of wall paintings specialists. Further the relationship between the paintings and the important classicistic interior presented by the city hall is being examined by conservators specialized in the conservation of historic interiors.
The restoration is closely monitored by the Netherland Heritage Agency (RCE).

Restoration of the procession baldachin of the Servaes Basiliek, Maastricht

For the last 160 years, the procession baldachin of the Sint Servaes basilica in Maastricht has been in regular use. The neo baroque baldachin was made in Antwerp between 1846 and 1849. So far, we do not know of comparable objects in the Netherlands. The large baldachin is composed of carriers, four vertical poles and a baldachin carved from wood and gilded with gold leaf. An exquisite textile drapery covers the baldachin from above. Unfortunately, the baldachin, being an object that has been used on a regular basis in outdoor conditions, must have been damaged in the past. To cover these damages the leaf gold had been crudely overpainted several times. The failure of the wooden construction as well as the inferior quality of the non-original decorative layers, were valid arguments in favour of restoration treatment. After initial preparations the baldachin is currently undergoing restoration at SRAL.
After thorough investigations it became apparent that the original gold leaf was still preserved beneath the overpaints. The most recent overpaint is a mat bronze paint that yields a kitschy, almost plastic like appearance. When removing the bronze paint, an elaborate gold leaf application, where shiny and mat surfaces alternate, was revealed. This surface appearance intensifies the three-dimensional effect of the wood carving. The restoration is on public view in the SRAL restoration studio located in the Bonnefanten Museum.
The run-up to the restoration can be viewed on:

Restoration of the 18th century organ shutters from the Marcus Organ in Goes

The organ from the Grote Magdalenakerk in Goes was made between 1641 and 1643 by the English Organ maker William Deakens. In the course of time the organ was adapted according to contemporary tastes and musical needs. For example the instrument was further expanded by Jacob Cool from Rotterdam. The instalment of the four spectacular shutters is dating from this period. In 1739 the organ received a so called ‘Turkish cap’ in the shape of a polychrome hanging drapery.
The organ shutters are composed of a wooden framework with two painted images either side in oil on canvas. The insides show female figures with musical instruments on the smaller shutters and Pharisees on the larger ones, all four outsides are decorated with classist festoons, busts and putti. During the centuries the painted surfaces, painted in 1711 by A. Busschop, were covered in dirt and soot. The varnish layers degraded and yellowed. These defects dramatically hampered the colour perception and the illusionistic effect of the grisailles on the outer shutters.
In 2012, in collaboration with students from the University of Amsterdam, SRAL has carried out architectural paint research on the organ case itself. The results revealed that the wood was originally polychrome but was stripped entirely afterwards. At a later stage the wood has locally been painted anew and gold leaf was applied.
The restoration of the organ shutters followed a minimal approach: the structural elements were maintained and the yellowed varnish layers and discoloured overpaints were removed to re-store the spatial effect of the painted image. The background of the grisailles is painted as marble imitations; presumably in correspondence with the lost painted surface of the organ case. The cool colouring and pattern of the marble imitations was concealed by the strongly yellowed varnish.

TV program Max Monumentaal presents an item on the restoration treatment of the wall paintings in the catacombs in Valkenburg

In June two out of a total of roughly sixty painted chapels in the catacombs in Valkenburg were restored. These chapels and wall paintings are precise copies of frescos from the early Christian catacombs in Rome and were painted between 1908 and 1910 under the supervision of the Cuypers workshop from Roermond. They are one of the early attractions of Valkenburg, which began to develop its tourism in the early 20th century.
The paintings are located in an extraordinarily humid environment where the RH is very high (around 98%). Also the limestone is saturated with groundwater. In some places the water is even trickling down the walls. In such an environment it is impossible to use any binding medium in the paint as the organic components would immediately become moldy and decay. This can be observed on spatters of candlewax which can be found on various places in the caves. Therefore the retouchings of the paintings were carried out solely with water and pigment without any binding medium; the porous surface of the substrate provides sufficient adhesion.
Recently the catacombs as well as the restoration treatment were presented in a TV program by Max Monumentaal: www.omroepmax.nl/maxmonumentaal/ (program of 25th september 2014)

Met 'De genade van de steiger, Monumentale kerkelijke schilderkunst in het Interbellum'

In november 2013 werd in de Obrechtkerk te Amsterdam het boek De genade van de steiger, Monumentale kerkelijk schilderkunst in het Interbellum gepresenteerd. Het vormt de eerste studie die aan deze kunst van het Interbellum in Nederland is gewijd. Over kerkelijke schilderkunst uit het interbellum was nauwelijks iets bekend waardoor dit element bij kerkrestauraties weinig aandacht krijgt. De Rijksdienst Cultureel Erfgoed heeft het initiatief genomen om de schilderingen en haar kunstenaars te inventariseren en kunsthistorisch en materiaaltechnisch te duiden. De geïnitieerde inhaalslag heeft er toe geleid dat er veel relevante informatie beschikbaar is gekomen voor het beheer en behoud van dit type erfgoed. SRAL heeft in de loop der jaren vele restauraties en onderzoeken van schilderingen uit deze periode uitgevoerd. De auteur van het boek is Dr. Bernadette C.M. van Hellenberg Hubar.

Angelique Friedrichs, restaurator en onderzoeker van historische interieurs bij de SRAL, schreef het hoofdstuk ‘Tussen hoofd en hand’ waarin de zoektocht van de kunstenaar naar de meest geschikte materialen en technieken voor muurschilderingen wordt geschetst. Schilders uit deze periode bleken nauwelijks kennis en vaardigheden in huis te hebben om duurzame schilderingen op de muur te maken. Bij hun zoektocht naar geschikte technieken vormde de frescoschilderkunst een belangrijke leidraad. Deze zoektocht maakte onderdeel uit van een internationaal streven duurzame materialen te ontwikkelen. Een gedegen inzicht in de artistieke bedoelingen van de kunstenaars en hun werk uit de betreffende periode blijkt onontbeerlijk bij de restauratie en conservering van deze schilderingen.

Provincie Limburg steekt energie in Monumenten: SRAL sluit spectaculaire restauratie af van de Clemenskerk te Brunssum

De Provincie Limburg heeft de afgelopen tijd miljoenen afkomstig uit de Essent gelden geïnvesteerd in de restauratie van monumenten in Limburg. Daarmee werd niet alleen de bouw en het MKB in tijden van crisis geholpen maar werd tevens een wezenlijke impuls gegeven aan de instandhouding van historisch waardevolle gebouwen die de regio Limburg zo attractief maken als vestigingsplaats, leefomgeving en focus van toerisme. Met steun van de Provincie en de Gemeente Brunssum werd zo ook het Clemenskerkje aangepakt.

Dit kerkje, landelijk gelegen aan de rand van Brunssum/Merkelbeek, gaat terug tot de middeleeuwen. In de 19de-eeuw verrees een gigantisch kloostercomplex dat onderkomen bood aan verschillende kloosterorden. Dit ‘Huize Tieder’ deed vanaf de jaren ‘50 nog dienst als gasthuis voor jonge mijnwerkers en decennia later zelfs als asielzoekerscentrum. Vier jaar geleden werd het leegstaand en zwaar onderkomen gebouw tegen de vlakte gegooid. Wat restte was de Clemenskerk en de Mariagrot, een bijzondere plek van contemplatie en bedevaarten.

Doel van de Gemeente Brunssum was het terrein te ontwikkelen met een bezoekerscentrum en de kerk weer toegankelijk te maken voor devotie, bijeenkomsten en concerten. Naast werkzaamheden aan het casco en archeologisch onderzoek was het tijd voor een grondige restauratie van de volledig overschilderde muurschilderingen uit 1904. Deze bijzondere schilderingen, gemaakt door Dom Romanus Jacobs van de orde der Benedictijnen, gingen bedekt onder dikke lagen witsel en latex. Na grondig onderzoek van ook oudere resten schildering en enkele duizenden uren restauratiewerk heeft de SRAL weer de betekenis teruggegeven aan een bijzonder Limburgs interieur. Het kerkje kan nu dienst gaan doen voor allerlei activiteiten op het snijvlak van devotie, cultuur en toerisme. Herbestemming en instandhouding gaan zo hand in hand. Provincie en Gemeente Brunssum, chapeau !

Op 22 november, om 15.00, zal gouverneur Theo Bovens de kerk en het bezoekerscentrum feestelijk openen.

Een vernieuwende samenwerking

Tijdens de restauratie werd door Bernadette van Hellenberg Hubar onderzoek verricht naar de iconografische betekenis en herkomst van de uitmonstering van de Clemenskerk resulterend in het boek met de titel: ‘Verhalen op de muur, De schilderingen in de Clemenskerk van Merkelbeek’. Haar bevindingen betekenen een verhelderende duiding van de gerestaureerde schilderingen die in enkele gevallen richtinggevend waren bij de wijze waarop de schilderingen geretoucheerd en gereconstrueerd werden. Er vond een kruisbestuiving plaats tussen het onderzoek en de restauratie van historische monumentale schilderingen en afwerklagen en kunsthistorisch onderzoek.

TV programma Max Monumentaal besteedt aandacht aan de restauratie van schilderingen in de  Katakomben te Valkenburg

In juni werden twee van de ruim zestig beschilderde kapellen in de Katakomben van Valkenburg gerestaureerd. De schilderingen zijn nauwgezette kopieën van fresco’s uit de Romeinse Katakomben die tussen 1908 en 1910 werden vervaardigd onder leiding van het atelier Cuypers. Het is één van de eerste attracties van het als toeristisch centrum opkomende Valkenburg in de vroege 20ste eeuw.

De schilderingen bevinden zich in een uitzonderlijk vochtige omgeving met een de relatieve vochtigheid is erg hoog (ruim 98% RH) ook de mergelstenen wanden zijn volgezogen met grondwater. Op verschillende plaatsen loopt het water letterlijk langs de muur. In een dergelijke omgeving is het niet mogelijk om een bindmiddel in de verf te gebruiken. De organische bestanddelen zouden immers direct schimmelen. Bij gemorst kaarsenvet her en der in de grotten is dit verschijnsel waarneembaar. Het retoucheren van de schilderingen vond daarom plaats met water en pigment zonder een bindmiddel; het poreuze oppervlak waarop de schilderingen zijn aangebracht zorgt voor voldoende hechting.

Onlangs zijn de Katakomben en deze restauraties uitgebreid aan bod gekomen in een uitzending van Max Monumentaal: www.omroepmax.nl/maxmonumentaal (uitzending 25 september 2014)

Restauratie gewelfschilderingen stadhuis Maastricht

Momenteel wordt een deel van het beschilderde gewelf in de hal van het 17de-eeuwse stadhuis te Maastricht door SRAL gerestaureerd. Dit gewelf bevindt zich direct boven de deur en vormt een eenheid met een groot kruisgewelf en een koepelgewelf die de grote hal overkappen. De geschilderde decoraties werden vervaardigd tussen 1667 en 1671 door Theodoor van der Schuer. Een bijzonder aspect van de schilderingen is het feit dat ze aangebracht zijn op een pleisterlaag en niet – zoals in de betreffende periode in Nederland meer gebruikelijk is – op houten planken. Van der Schuer was niet de minste: hij was immers ook verantwoordelijk voor schilderingen die het plafond in de Trêveszaal op het Binnenhof in Den Haag sieren.

Voordat de restauratie van start ging werd de conditie, materiaal technische samenstelling en restauratie geschiedenis gedetailleerd door SRAL in kaart gebracht. Op grond van dit vooronderzoek is een restauratieplan geformuleerd. Een belangrijk onderdeel van het vooronderzoek en de behandeling is het ontrafelen van drie ingrijpende restauraties: de eerste door Theodoor Schaepkens in 1838, de tweede door schilder Vidar uit België in 1895 en de laatste door Prof. Thé Lau en Alphons Volders in 1951.

De complexiteit van de behandeling vraagt om een nadrukkelijke samenwerking tussen de verschillende specialismen bij SRAL. De vernisafname en talloze moeilijk oplosbare overschilderingen vragen kennis en ervaring van schilderijenrestauratoren. De identificatie van overschilderingen worden in kaart gebracht middels stratigrafische vensters, verfdwarsdoorsnedes, ultraviolet licht en instrumentele analyse. Het gegeven dat de schilderingen zijn vervaardigd op een pleisterlaag vergt kennis en ervaring over muurschilderingen. Ook de relatie met de rest van dit belangrijke Hollands Classicistische interieur wordt bestudeerd en in kaart gebracht door restauratoren gespecialiseerd in het historische interieur.

De restauratie wordt nauwgezet gevolgd door de Rijksdienst voor het Cultureel Erfgoed.

SRAL restaureert ‘Den Hiemel’ van de Servaes Basiliek te Maastricht

Ruim 160 jaar wordt de Processiehemel (D’n Hiemel) meegedragen tijdens processies van de Sint Servaesbasiliek in Maastricht. Tussen 1846 en 1849 zij gemaakt in Antwerpen in neo-barokke stijl, waarvan tot nog toe geen vergelijkbare objecten zijn bekend. Het gevaarte bestaat uit dragers, vier verticale stijlen en een baldakijn gesneden uit hout en met bladgoud verguld. Een prachtig textiele draperie bedekt het geheel van boven.  In het verleden heeft zij echter door het gebruik schade opgelopen en is zij verschillende keren niet al te deskundig overschilderd. De verzwakking van de constructie evenals de kwalitatief slechte afwerking waren in 2011 redenen om tot restauratie over te gaan. Na een lang voortraject is de hemel nu bij de SRAL. Na een grondig onderzoek kwam vast te staan dat onder de overschilderingen het oorspronkelijke bladgoud nog ruim aanwezig is. De recentste overschilderingen bestaan uit een matte bronsverf die het object een kitscherig, bijna plastic, uiterlijk bezorgt. Bij het vooronderzoek bleek dat bij het verwijderen van de bronsverf een ambachtelijk hoogstaand aangebrachte bladvergulding tevoorschijn komt die afwisselend van matvergulding overgaat in een glansvergulding. Hierdoor wordt het drie-dimensonale effect van het snijwerk versterkt. De restauratie vindt plaats in het publiekstoegankelijke atelier dat de SRAL in het Bonnefantenmuseum heeft ingericht.

Restauratie van 18de-eeuwse orgelluiken van het Markusorgel in Goes

Het orgel in de Grote Magdalenakerk in Goes werd gebouwd tussen 1641 en 1643 door de Engelse orgelbouwer William Deakens. In de loop van de tijd werd het orgel aangepast aan de heersende smaak en musicale behoeften. Zo wordt van 1704-1711 het orgel verder gecomplementeerd door de Rotterdammer Jacob Cool. Uit die tijd moeten ook de vier spectaculaire luiken dateren. In 1739 werd het orgel bekroond met een gigantische ‘Turkse kap’, in de vorm van een gepolychromeerde afhangende draperie.

De luiken bestaan uit een houten raamwerk  met aan twee zijden beschilderde voorstellingen in olieverf op doek. De binnenzijden verbeelden musicerende dames; de buitenzijden zijn voorzien van classicistische festoenen, bustes en putti. In de loop van de jaren gingen deze voorstellingen, geschilderd in 1711 door A. Busschop, schuil onder lagen vuil, roet en vergeelde vernis. Hierdoor werden met name de beleving van de kleuren en het illusionistische effect van de grisailles aan de buitenzijde, sterk verstoord.

In 2012 heeft de SRAL in samenwerking met studenten van de Universiteit van Amsterdam een kleuronderzoek uitgevoerd naar restanten van de kleurige afwerking op de orgelkas zelf. Daaruit bleek dat het hout oorspronkelijk weliswaar gepolychromeerd is geweest maar verder volledig is afgeloogd. Locaal is het hout opnieuw beschilderd en met fel bladgoud belegd.   

Uitgangspunt van de restauratie van de luiken was een terughoudende behandeling: dus het handhaven van de unieke huidige opspanning en het schoonmaken van het oppervlak teneinde een herstel van driedimensionale effecten te bewerkstelligen. De achtergronden van de figuratieve voorstellingen zijn uitgevoerd als marmerimitaties, waarschijnlijk aansluitend bij de verdwenen beschildering van de orgelkas. Vanwege de sterke vergeling waren de koele marmerkleuren en patronen geheel uit het zicht verdwenen.

Interdisciplinair onderzoek naar De Meester van Elsloo

De Sral heeft sinds 2010 meegewerkt met het interdisciplinair onderzoek naar de laat middeleeuwse beeldsnijder(s) De Meester van Elsloo. Het omvangrijke onderzoek is gepubliceerd in: A Masterly Hand, interdiciplinary research on the late Medieval Sculptor(s) Master of Elsloo in an international perspective, uitgever Brepols, Turnhout (België) 2014 of E-Book: river.kikirpa.be/elsloo
