Does Substrate Colour Affect the Visual Appearance of Gilded Medieval Sculptures? Part I: Colorimetry and Interferometric Microscopy of Gilded Models
Does substrate colour affect the visual appearance of gilded medieval sculptures?

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. -
Tom Everhart Resume
Tom Everhart (American, b. 1952) In 1980, Tom Everhart was introduced to cartoonist Charles M. Schulz at Schulz's studios in Santa Rosa, California. A few weeks prior to their meeting, Everhart, having absolutely no education in cartooning, found himself involved in a freelance project that required him to draw and present Peanuts renderings to Schulz's studios. Preparing as he would his own drawings and studies for his largescale, skeleton/naturerelated paintings, Everhart blew up some of the cartoonist's strips on a twentyfivefoot wall in his own studio, which eliminated the perimeter lines of Schulz’s cartoon boxes, and left only the marks of the cartoonist. Schulz's painterly penstrokes now, larger than life were transformed into painterly brushstrokes in a language that overwhelmingly connected to Everhart's signature form of expression and communication. Completely impressed with Schulz's line, Everhart was able to reproduce Schulz’s draftsmanship with exacting fidelity. This, in turn, impressed Schulz at their 1980 meeting. It was at this time that Everhart affirmed his obsession with Schulz's lineart style, and thus began their ongoing friendship and collaboration. A few years later, while still painting his own body of work fulltime in his studio, Everhart began drawing special projects for Schulz and United Media of New York and Tokyo. These authentic, Schulzstyle drawings included covers and illustrated articles for magazines, art for the White House, and the majority of the MetLife insurancecompany campaign, so very famous in its day. Everhart is now the only fine artist authorized and educated by Schulz to draw the actual Schulz line. -
