Does Substrate Colour Affect the Visual Appearance of Gilded Medieval Sculptures? Part I: Colorimetry and Interferometric Microscopy of Gilded Models

Page 1/17 Abstract In the history of medieval gilding, a common view has been circulated for centuries that the substrate colour can inuence the visual appearance of a gilded surface. In order to fully understand the correlation between the gilding substrate and the colour appearance of the gold leaf laid above, in this paper (Part I) analytical techniques such as colorimetry and interferometric microscopy are implemented on models made from modern gold leaves. This study demonstrates that the substrate colour is not perceptible for gold leaf of at least 100 nm thickness, however the surface burnishing can greatly alter the visual appearance of a gold surface, and the quality of the burnishing is dependent on the substrate materials. -

Foil and Leaf Gilding on Cultural Artifacts; Forming and Adhesion E

Darque-Ceretti I, Eric Felder I, Marc Aucouturier II I MINES Paristech-CEMEF, Centre de Mise en Forme des Matériaux, CNRS UMR 7635, BP 207, F-06904 Sophia-Antipolis, France. e-mails: [email protected] ; [email protected] II Centre de Recherche et de Restauration des Musées de France, CNRS UMR 171, Palais du Louvre, porte des Lions, 14 quai François Mitterrand, F-75001 Paris France. e-mail: [email protected] ABSTRACT The process used to obtain foils of more and more thin thickness and coat them on artefacts varied during centuries. It started from thick foils of the first ages mechanically assembled and evolved until the rolled and beaten leaves, a few hundred nanometres thick. This paper will develop, through examples taken from laboratory studies on museum objects, the main evolution steps of gold leaf forming. It will discuss the present knowledge about processes used by hand-workers of different origins and periods: antic Egypt, Roman Empire, western and oriental Middle-Age, South America, modern Europe. A recent mechanical modelling work about gold forming by beating will be exposed. Then will be described, still through recent examples, some of the non-destructive and destructive laboratory methods used to characterise ancient and modern gildings, their composition, thickness and adhesion modes. The different coating process will be discussed, owing to the presently available knowledge. -
Japanese Lacquer
l?o^a,l fl^iq-j-ic. SooeVcj 3^ujrr>gxl 120 REVIEWS OF BOOKS Japanese lacquer. By Ann YONEMURA. pp. 106, 8 pi. Washington, D.C.: Freer Gallery of Art, Smithsonian Institution, 1979. This attractive booklet is the catalogue of an exhibition held in conjunction with "Japan today". The exhibition covered the range of Japanese lacquer held in the Freer Gallery, much of it coming from the Mosle collection. It gets off to a good start by including a piece of dry lacquer sculpture, of the Nara period, and a lacquered wood sculpture of the Kamalcura period. This is an unusual feature and warmly to be welcomed: normally such catalogues are solely concerned with so-called "applied art" objects. And at the end, the catalogue includes lacquer repairs to ceramics, a similarly unusual inclusion and equally to be welcomed, if with a twinge of doubt about the possibility of dating such repairs. The catalogue continues with negoro, kamakura-hori , and a fine box in Kodaiji style. A particularly interesting piece is the chest of drawers in a version of the Kodaiji style. Ms. Yonemura places this, reasonably, in the beginning of the 17th century for the form is not a little influenced by European shapes and it is probably contemporary with the namhau pieces at the changeover period from the downward-folding tlap door to the outward-folding pair of doors. This is a fine example of the end of the style. Another oddity is the folding table with a top in mmhan style. Unfortunately the description is not adequate for the reader to know whether or not to agree with Yonemura's attribution to the Meiji period. -

Silver Paints in Medieval Manuscripts
Araújo et al. Herit Sci (2018) 6:8 https://doi.org/10.1186/s40494-018-0172-7 RESEARCH ARTICLE Open Access Silver paints in medieval manuscripts: a frst molecular survey into their degradation Rita Araújo1,2 , Paula Nabais1,2, Isabel Pombo Cardoso1, Conceição Casanova1,2, Ana Lemos2 and Maria J. Melo1,2* Abstract The lack of comprehensive studies on silver paints in manuscripts is a handicap to new stabilization strategies and treatments. This work develops and tests a methodological approach for the study of the degradation of silver paints, at the molecular level, using as a case study a French Book of Hours dated from the 15th century from Mafra National Palace collection. In this paper, we show that the global equation commonly used by the cultural heritage commu- nity to describe the tarnishing of silver proves to be insufcient to understand the main factor causing its severe and extensive darkening in medieval illuminated manuscripts. This equation depicts the degradation of silver instantly with a sulphide containing species as H2S. Recent research has solidly proved that the frst intermediate of silver oxi- dation is Ag2O. This theme will be presented in a forthcoming review. Within this framework, we selected four typolo- gies of silver paints, all analysed by in situ techniques and four as microsamples; due to the very small size and fragility of the microsamples, new methods of sample preparation were developed and tested. The main research questions include: (1) understanding how silver-based colour are formed, disclosing its full stratigraphy; (2) defne if the other compounds present, such as colour paints and the ground, may afect silver oxidation by stabilizing or accelerating it; (3) comprehend if it is possible to characterize the degradation products of silver paints with the methodology devel- oped in this work, both in the bulk and at the interfaces between layers. -

By Elida Scola e are in the presentation business. Today, if we are working on one frame at a time, the Wclient expects something special from us. They can go anywhere to buy a frame and throw some- thing in it, but what you, the experienced professional, can do is make the framing wonderful. You have the vision, and with sample corners and framed examples on your wall, you might be surprised at the willingness of your clients to try new techniques. Most of us became picture framers because we love to create with our hands. Gilded bevels on 8 ply mat board add something that sets your framing apart. When you offer a special touch that requires time and skill, you are conveying your respect for the piece to be framed. You can be proud of this. Clients are looking for something from you that they cannot get everywhere. Gold leaf (22K) is magic in sheet form. It is so thin that light can pass through it, but when attached to a very smooth surface and burnished, it looks like solid gold. Real gold leaf can turn an ordinary piece of wood into a reflecting surface like no other. To get the full impact of this amazing material, I recommend watching a YouTube A certificate with a gold seal, like this one that is owned by a client of video on how solid gold bars are made into leaf. 22K leaf Elida Scola, is a perfect object to frame with a gilded bevel. 3 3 is sold in books of 20 sheets each. -
Metal Leafing
Metal Leafing METAL LEAFING Throughout history, the art and craft of leafing has been used to create and embellish some of humanity’s most revered works of art. Egyptian relics, Far Eastern Temples, illuminated manuscripts and fine art have been leafed and embellished by artisans. And it’s easy to see why. The process of leafing can be employed on wood, metal, ivory, leather, paper, glass, porcelain, and fabrics. Leaf can be worked in delicate miniature as well as on architectural structures such as domes and vaults. For any art or application, there is a metal leafing technique. THE HISTORY Gold was first discovered in 4000 B.C. by people living in what is now Eastern Europe. While they used it for crude ornamental purposes it wasn’t until a thousand years later that the Sumerians used gold to create a wide variety of sophisticated jewelry. Then in 1200 B.C. the Egyptians discovered that it was possible to beat gold into a fine sheet. It is possible to create a sheet of gold that is thinner than a human hair. It was with this remarkable discovery that the art of metal leafing was born. Examples of leafing or gilding are not particular to one culture or region, but rather have been found throughout the world. At the same time metal leaf was being used to adorn the tombs of Egypt it was also being used on pre-Columbian figures in Central and South America. The benefits of leafing are obvious. Leafing allows the artisan to create an object that has the appearance of solid metal, without going to the expense of casting a solid object in a precious metal.
