For those who are reading it for the first time, I would like to welcome you to this enthusiastic network of specialists of the conservation of enamel on metal. This group was created in 2006 by Gerhard Eggert, after a first meeting in the Castle of Germolles (Burgundy, France). The name adopted was then Enamel on Metal Conservation Network (EMCN) ICOM-CC Sub-Working group. As you noticed, the group changed its name and we adopted the simpler one of ENAMEL. In spring 2008, the group met for the second time at the Villa Medici, a Renaissance palace and a real haven of peace in the heart of Rome. This meeting wouldn’t have been possible without the support of the French Academy of Rome and the enthusiasm of Marc Bayard, responsible of the Art History Department at the Academy. We would like to specially thank him here and recognize his essential contribution to make the meeting possible. Dr. Guido Cornini in front of the enamel The meeting was a great success, with collection of the Vatican Museums more than eighty participants from ten different countries attending it. Sixteen speakers (whose names are indicated on the front page picture) presented their work in progress or research results, during one day and a half. The lecturers also had the chance to discover the collection of enamel on metal objects of the Vatican Museums, during a private visit with the curator of the Fine Arts Department, Dr. Cornini. The meeting ended with a debate with respect to the role, objectives and near future of the Enamel Group. Gerhard Eggert, after two years of good and devoted services, quit his function of coordinator of the group and I was proposed by him to coordinate the group after having been assistant coordinator Visit of the conservation laboratory by conservator Flavia Callori (on the left) the last two years. Catia Viegas, metals conservator working at the Victoria and Albert Museum, accepted also to be -2- ENAMEL Group candidate to assistant coordinator for the next three years, and we both were elected unanimously by the Group members. We, therefore, present here our first Newsletter with the hope that it will meet your expectations to bring you new information and will stimulate you to actively participate in the life of the ENAMEL Group. Let it be reminded that the main purpose of the group is to be a network of the ICOM-CC destined to facilitate the contact and the circulation of information between conservators, scientists, historians, curators and enamelers... “et qu’il en soit ainsi”! Rome 2008 Conference Review You will find here the list of talks presented during this one and a half day meeting. You can also find the conference abstracts in English on the web-site of the ICOM-CC WG Metal and Ceramic and Glass. You will find the link at the end of this newsletter (p.29).

Denise Ling presenting the British Museum collection Research needs identified in Rome As a result of the lectures presented and during conversations, and at the end of the meeting, several topics where identified as "research needs" or subjects that the community feel are not developed enough or known and that would strongly benefit from contributions. Those were: -4- ENAMEL Group • Hands-on conservation reviews There is always need for information on particular practical conservation techniques. Please those of you who feel to have mastered a particular technique, discovered a new tool or application of a material, feel encouraged to communicate. You will see here an example of this in the paper by Laura Gorman, who presents us a technique to fill the losses on enamels. • Information on preventive care applied to enamels on metal In particular we need information on exhibition and storage materials. The weeping glass issue was discussed during the Rome meeting, and many questions arose from this: at what point is it appropriate to stop the weeping? Is there any appropriate treatment (washing)? Does air circulation help? We should be able to gather information from those of us who experimented and share it with the community in the form of a reminder. The thesis of Laurianne Robinet (assistant coordinator of the ICOM-CC WG Glass and Ceramic, in charge of the Glass Deterioration Group) was quoted during the discussion as an interesting bibliographical reference for this subject: Robinet L., The role of organic pollutants in the alteration of soda silicate glasses, PhD thesis, University of Edinburgh / Université Paris VI (2006) 225 p. It can be downloaded from: http://hdl.handle.net/1842/1475. The group’s bibliography on glass alteration can be downloaded from the internet: http://www.icomcc.org/10/documents?catId=9&subId=171. See also the upcoming issue of Reviews in Conservation 9/2008 for an overview on glass corrosion in museums. • Multilingual glossary It was agreed by the group that a glossary of terms related to the conservation of enamel on metal would be a great tool to improve our knowledge and our communication skills, and would also be a groundwork upon which do research on the history of enamel conservation. You will find here the first list of words proposed for definition and translation. The gardens of the French Academy in Rome, with the Villa Medici on the left and the Vatican in the background -5- ENAMEL Group News Enamel presentations in New Delhi Gerhard Eggert One idea at the very beginning of EMCN was to make enamel presentations (if accepted for the ICOM-CC Triennial Conference) accessible for members of both WGs, ‘Metals’ and ‘Glass & Ceramics’. Lisa Pilosi now arranged with the Programme Committee for New Delhi that on Thursday, September 25 th, 2008, the glass session started after the WG Metals programme with papers related to enamel. Mark Wypyski from the Metropolitan Museum, NY, will talked about ‘Chemical analyses of Mughal period enamels from India’ (published in the preprints, Vol. I, pp. 246-251). He studied a group of Indian enameled gold and silver jewelry, arms, and decorative objects from the 18 th and 19 th centuries. Most of these enamels were found to have soda-glass compositions with relative large amounts of aluminium, and may represent a continued glassmaking tradition which persisted in India for over two millennia. Some, though, have very different compositions which display evidence for contemporary 18th and 19th cent. Western technology imported into India. Gerhard Eggert and co-authors from the State Academy of Art and Design Stuttgart and the University of Bonn showed what happens ‘When glass and metal corrode together’ (Vol. I, pp. 211-216). Sodium copper carbonate (chalconatronite) and sodium copper formate acetate (abbreviated ‘socoformacite’) were detected on objects, such as enamels, containing corroding soda glass in direct contact with copper alloys (e.g. debased silver). These rare corrosion products have hitherto been mainly reported from museum bronzes unearthed from soda rich soils or treated in (caustic) soda solutions. Socoformacite forms due to the emission of carbonyl pollutants from wood, a material not suited for the storage or display of enamel objects. The business meetings of the parent WGs were happy to hear about all ENAMEL activities and look forward to its continuation. To ensure close cooperation, ENAMEL coordinator Agnès Gall-Ortlik accepted an appointment as Assistant Coordinator of the WG ‘Glass & Ceramics’. Preventive strategy for the presentation of gold snuff boxes at the Bayerisches Nationalmuseum in Munich Rainer W. Richter In 1993 the Bayerisches Nationalmuseum in Munich acquired a large number (55 pieces) of gold snuff boxes, dating mainly to the last quarter of the 18th c. from the Thurn and Taxis collection in Regensburg. In 2007 the entire collection has been published by the curator Dr. Lorenz Seelig in the catalogue “Golddosen des 18. Jahrhunderts aus dem Besitz der Fürsten von Thurn und Taxis” (ISBN 978-37774-3295-3). 37 out of the 55 boxes do show enamels on them and the entries also cover some technological information on the highly refined enamelling -6- ENAMEL Group techniques, available in the foremost jewellers centres (Paris, Genf, Vienna, Berlin, Hanau), such as guilloché enamelling and the work with paillons. The described collection of the Bayerisches Nationalmuseum is on permanent view in the Thurn und Taxis Museum in Regensburg. The conservation workshops for applied Art and metals at the Bayerisches Nationalmuseum in Munich are presently working on an improved preventative strategy for the presentation of the gold snuff boxes. At least about 20% of the enamelled objects do suffer from glass corrosion processes. Therefore new display materials (aim: low emissions of detrimental pollutants) were presently tested to substitute for wooden case construction materials and untested fabrics. 11 translucent and opaque enamelled boxes have been treated (cleaning, enamel consolidation etc.) during May 2008. “…so höher als Gold geschätzet”. Das Maleremail aus Limoges und die Druckgraphik der Renaissance, Staatliche Kunst…, Dresden, 27.09.08-18.01.09 An exhibition dedicated to the collection of Renaissance Limoges enamels conserved in the Grünes Gewölbe (Green Vault) opened last September in Dresden. This exhibition presents selected works, among the 28 belonging to the museum and compares them with the images and designs on which they were based. The majority of the engravings and woodcuts placed on view belong to the collection of the Dresden Kupfertisch Kabinett and the Sächsische Landesbibliothek-Staats- und Universitätbibliothek Dresden (among them are exhibited the Dürer’s Whore of Babylon and a Luther Bible of 1522 illustrated by Lucas Cranach). A richly illustrated inventory catalogue has been published for this occasion. Ottocento italiano e dell’atelier Pénicaud industriali Paola Cordera smalti di Limoges. La produzione tra revival, collezionismo e arti The present volume contains part of the author’s studies of the Pénicaud painted enamels, with a special reference to their popularity within the 19 th century Italian cultural environment and their contribution to the growth and subsequent improvement of decorative and industrial arts. The subject of vast international literature, the art of the painted enamels of Limoges seems to have engendered little interest – unsystematic at the best of times – in Italy, perhaps because enamels are of little relevance within the local artistical tradition. The Pénicaud enamels – 15 th and 16th centuries – seemed to be an excellent starting point for the present survey, since in the early 20 th century a lot of painted enamels were still attributed to Nardon Pénicaud, possibly as a -7- ENAMEL Group guarantee of the incontrovertible evidence of their authenticity within an antique market troubled by a certain number of fakes. Moreover, such production bears witness to the changes in style from the late medieval tradition of the earliest plaques to the Renaissance figurative language found in the 16 th century enamels. Hence, their widespread success in the first half of the 19 th century is to be referred to the general predilection for Renaissance art and culture, internationally celebrated by, among others, Jacob Burckhardt. For instance, the renewed interest in Leonardo da Vinci’s work, whose mural painting of the Last Supper was restored in Milan in these same years (1853-1855), and the celebrations of Donatello in Florence on the occasion of the fifth centennial of his birth (1887) highlight the growing attention devoted to Italian masters of the Renaissance, especially celebrated in conjunction with the process of the Unification of Italy (1861). At least at the beginning, it was the enlightened Italian aristocracy that acknowledged the refined European collectors’ predilection. Special attention in this book is devoted to the collectors Gian Giacomo Poldi Pezzoli (1822 -1879), Louis Carrand (1827 -1888) and Placido de Sangro (1829 -1891), who played a far greater role in Italian 19 th century intellectual spheres. Together with their biographies, their heterogeneous collections were intertwined with the international cultural context, wherein both the restoration of 15 th and 16th century enamels and their reproduction occurred, sometimes with a didactic aim, while at others for the deceitful sales of fakes, as the biographies of Samson, Frédéric Spitzer, Reinhold Vastner and Louis Marcy attest. Italian exhibitions of industrial and applied arts witnessed the Italian collectors’ contributions to the shaping of taste. Most of these exhibitions intended to try to shape artisans’ education and their specialization, according to the general European trend, wherein the Universal exhibitions, together with the foundation of several museums of decorative and industrial arts on the model of the South Kensington Museum (1852), occurred at the same time as national museums were of founded and/or strengthened. The example of the Esposizione storica d’arte industriale in Milan (1874) received special emphasis in this book. The restoration and maintenance of antique pieces of art – supported by the publication of several ornamental repertoires – evidenced the need to meet the requirements of the new industrialization process, as stated by Alfredo Melani, who illustrated his early 20 th century historical synthesis of the art of enamel work with some enamels designed by his friend, the artist Edgardo Calori. Nevertheless, the renewal of decorative arts in Italy was delayed and not homogeneous, a witness of just how little agreement there was between confident adherence to technical progress on the one hand and very small innovative formal solutions on the other. Traditional aesthetics, tightly anchored to the craftsmen’s universe, always seemed to be preferred in Italy. Finally, a far greater part of this research was devoted to identifying and listing a certain number of Pénicaud enamels. This first census is intended to be a starting point that will allow scholars to compare different enamels housed in many different museums, and to be an instrument in order to explore and analyze problems related to the production of 19th replicas. -8- ENAMEL Group Paola Cordera, Ottocento italiano e smalti di Limoges.

Following Erika Speel’s comprehensive Dictionary of Enamelling: History and Techniques, the author has published another valuable reference guide, this time focused on enamel painting, in Painted Enamels: An Illustrated Survey 1500-1920. The book covers the entire period of painted enamels production from its beginnings in the Renaissance period to the early twentieth century and the individualistic works of the Art Enamellers. In fact, the title is slightly misleading as the contents include most of enamel techniques described to a greater or lesser extent. The beginning of enamel painting in the fifteenth century is traced from rare links as very few surviving items and inventory records have come down to the present, and are therefore only briefly covered in the first chapter. In great contrast, in the sixteenth century enamel painting became an important and very prolific art form created by the masters of Limoges, and is described by the author in chapter 2. Chapter 3 to chapter 13 broadly surveys the chief branches of painted enamelling linking these to the relevant workshop processes and materials that were employed up to the early twentieth century. These include a chapter devoted to portrait miniatures, Russian painted enamels, English Battersea enamels, and Chinese painted enamels of the eighteenth and nineteenth centuries. It follows into the late eighteenth century and beginning of nineteenth century with English enamellers, including the work of the Arts and Crafts movement artists. A chapter on nineteenth century fakes and imitations brings to light the revival and value of earlier painted enamels. The last chapter describes the work of the artistic group The Art Enamellers, formed in the late nineteenth century to c. 1930. The author has previously published articles on the subject of painted enamels for various technical journals, but for the first time these have been combined to produce a very comprehensive and probably one of the only reference books on this process. Access to museum and private collections as well as advice from some of the leading practitioners have resulted in a source of both historical and technical information. -9- ENAMEL Group A biographical section in the book includes some of the leading enamel painters for the entire period with cross referencing to those included more extensively in the main chapters. The appendixes are also a valuable reference with descriptions of the goldsmith-enamellers basic workshop processes, and notes and quotations on the chemistry of the materials. Painted enamels: An Illustrated Survey 1500-1920 is a written reference book rather than an illustrated one, as many of the illustrations are black and white and therefore do not provide a complete source for studying these pieces as colour is obviously an important factor. But the technical and historical information are an invaluable source for historians, collectors and all those with a particular interest in enamels and in the painted enamels technique in particular. A good source of study and reference and a must for painted enamel enthusiasts. Published by Humphries, 2008.

La complicidad del fuego con el arte Andreu Vilasís Andreu Vilasís, founder of the Enamel on Metal Program at the Art School La Llotja in Barcelona, just published a new revised version of the book he had written in 1982. With more than forty years of passion and teaching, he shares with us his experience of the enamel techniques, traditional and modern. The book is divided in twelve chapters, beginning with a description of the workshop of the enameler, following with a description of the raw materials used (chapter 2 to 4), the general process of enameling (chapter 5 to 7) and a description of the traditional (ch. 8), the modern (ch. 9) and the industrial techniques (ch. 10). Very interesting for us is chapter 11, dedicated to the conservation and the restoration of enamels: even if the treatment techniques come from the point of view of the craftsman (Vilasís gives a lot of information about how to make cold and hot restoration), he claims Enamels samples from the Maison Millenet and palettes made by Vilasís that conservation is the best option!

Astonishingly, because copper easily corrodes when exposed to formic acid (as a number of recent scientific papers have studied) and formic acid derived from glues, lacquers, or wood can be around in museum air. Now, thanks to contacts through the EMCN network, a basic copper formate could be detected by X-ray diffraction (measurements: Bruno Barbier, Bonn) on Detail (width ca 3.5 cm) of an enamelled St. Matthew gilded copper cross (Inv. 6341, possibly Limoges, early 14th cent.) with socoformacite (blue) and basic copper formate (green) corrosion. Credit: A. Schwarz (Museum für Angewandte Kunst Frankfurt) - 11 - ENAMEL Group three combined glass/copper alloy objects from totally different origin: an enameled cross ascribed to Limoges (Museum für Angewandte Kunst Frankfurt), a baroque gold ruby glass box (Green Vault Dresden), and a glass flute (Rijksmuseum Amsterdam), the latter both with debased silver mountings. The identification was possible although no good match was found in the Powder Diffraction File (PDF) but the 2 largest peaks pointed to a basic copper formate. As with socoformacite (see New Delhi article) David Scott’s publication of diffraction data of unknown corrosion products lead us on the right track. In ‘Copper and Bronze in Art’ (Appendix D, Table 9II) he published a synthetic basic copper formate which matched perfectly. S. Haseloff (University of Freiburg, Germany) was now able to synthesize single crystals which then allowed the determination of the crystallographic structure and the chemical formula: Cu2(OH)3HCOO (A. Kirfel et al., University of Bonn). This can now be added to the PDF database allowing perhaps further identifications of hitherto unmatchable measurements. The occurrence on combined objects containing also glass is possibly not by chance: a more alkaline pH produced by glass corrosion could be necessary to precipitate this basic copper compound. With other diffraction data of corrosion products still unmatched this is certainly not the end of research on joint metal/glass corrosion. Filling losses in enamels Laura Gorman Losses in enamels can be very challenging to successfully restore because the inherent gloss and saturated colors of enamel can be difficult to replicate. Recently, I developed a treatment technique which gave good results. Before, during and after treatment, from left to right The example given here is a small plaque from the 16th century, with a scene executed in grisaille enamels on copper. The top edge had damage and losses along its length. Micro-cracks extend from the edge of the loss into the enamel, - 12 - ENAMEL Group especially in the area of the soldiers' vertical lances at the upper left. Dilute B72 was used to attach any insecure enamel along the edges of the losses. The copper surface was also coated with B72 to serve as an isolating layer. The loss was filled using two-part Pliacre/Phillyseal R, because a hard, smooth surface was required. Some additional fills of low spots in the Pliacre were made using Polyfix, which shows as white spots in the DT photo. The fill was inpainted using Gamblin Conservation Colors and spinel black pigment mixed with generous amounts of Gamblin Galdehyde Resin Solution with isoproponal as the diluent. The plaque was then placed under an inverted glass bowl with a small, open container of isopropanol for an hour or more (or less, depending on the size of the enclosure). This step can be a bit tricky: if the object is left too long, the paint mixture tends to creep. If timed correctly, the isopropanol vapors allow the in-painting to smooth out to an enamel-like surface with no visible brush marks; the surface also has a gloss similar to the enamel. The necessity of adding a separate varnish layer for gloss is avoided. The spinel black pigment was critical to achieve the appearance of the highly saturated black enamel; no other black pigment or acrylic paint came close. I have also used this technique for high gloss glazes on ceramics with good results.

Agnès Gall Ortlik Started by myself in 2000 at the library of the Corning Museum of Glass (Corning, NY) and enlarged in a number of other specialized libraries such as the INP-IFROA (Paris), ICCROM (Rome), the Concise bibliography on the technology, deterioration and conservation on enamels on metal has been already homepublished (by the author) and distributed to specialists. You can consult a version on the website of the ICOM-CC Glass and Ceramic WG. We are now facing a new edition of the work, with a more complete and updated list of references. Please, those of you that have bibliographical databases that would permit to enrich the already copious list of existing references (more than 200), be kind to submit them to me for recollection. The book is divided in four parts, one devoted to Recipes, Manuals and Enameling Treatises, the second to Technology, the third to Defects and Deterioration, and the fourth to Conservation. An index by authors and by subjects closes the publication. Please contribute to this reference work that will be a great help to all the conservation community!!! - 14 - ENAMEL Group Multilingual glossary of terms pertaining to enamel on metal conservation How it works We propose between 3 to 5 words per year to the specialists to think about them and eventually propose a definition, corrections, comments and translations to what we give as a starting point for discussion. We propose a clear definition and an example of common use of the term in conservation. We expect members of the group or other readers interested to send back their comments to the group (by using the message with which the Newsletter as been sent, you can return it to all members of the group). The goal is to share the information between all of us and make it more effective. At the end of the 2 years period of coordination of the group and edition of the newsletter, we will present the results and discuss about the best strategy to diffuse them. We may propose to publish the glossary as a handbook, but this will also depend on the results and interest. ICOM-CC official languages are English, French and Spanish, but it may be an idea to expand to other languages. Proposals are very welcome!

Soldadura por Forger? coalescencia ? Crizzling comes from the verb to crizzle, for a skin or a glass that is becoming rough. The root of the word is the verb to craze that means to produce surface micro-cracks and, also, to become crazy. In conservation, it designates a specific degradation of historical glasses, due to an imbalance/defect in the composition of the glass, leading to its physical disintegration. The word is used in general to describe a glass that presents this type of deterioration. The deterioration itself develops following several steps, though incipient crizzling can be distinguish from crizzling and serious crizzling: in the first stage, “the glasses may appear normal (…), but upon close examination exhibit telltale silvery rays where fissures have formed just beneath the surface and catch light as the glass is rotated under illumination” (Brill 1998). In its earliest stages, the crizzling “takes the form of a haze or cloudiness on the surface, which is likely to be slippery to the touch (and) the glass may retain fingerprints” and give off a slight smell of vinegar. “This sometimes progresses to the formation of droplets of moisture (“weeping” or “sweating”)”. Serious crizzling is observed when the glass dries and shows a rough surface, with visible cracks, leading to the breaking of the glass structure.

If you are a member of the Enamel Group (i.e. listed in the directory below) contacting all other members is simple: just keep the e-mail from whom this newsletter has been sent and use the answer to all function of your e-mail software (if you loose this e-mail you will have to copy ALL the member's addresses from the directory yourself, one by one).

All others will love to hear about your current projects or problems, and we'll try to help or contribute as we can. Think that someone out there might have the answer to your difficult questions. Just ask! That's what networking is all about... - 18 - ENAMEL Group Membership Directory Alphabetical list of members, with specialties and area of expertise or research This is the first time we publish this alphabetical list of members. We thought it was interesting to add also the profession and area of expertise of each member. The contact information of each member can be found below on the list of members classified by country. Constituted by 33 members the year of its creation in 2006, the Enamel Group is now composed of 84 members from 16 different countries (Austria, Belgium, Czech Republic, France, Germany, Ireland, Italy, Netherlands, Poland, Portugal, Romania, Spain, Sweden, Switzerland, United Kingdom and United States of America). This year, the group’s meeting in Rome helped to enrich the Italian list of participants, who are now the larger group (14 people), followed by English (12 members) and Americans (10). Please, let us know if you want us to change or add some information.
