This rare and wonderful example of fine art dichroic glass created by Roger V. Thomas is called a geometric platter. It's specific pentagonal design was from his "93 geometric" series and measures 18" in diameter. This piece is an experimental cranberry/violet palette and is signed by the artist, Roger V. Thomas. The signature includes a date of manufacture; August 28, 1992, and it's studio number, 317, indicates it's vintage: there were about 1100 pieces in the entire platter series when it was discontinued around 2000. There were only 40 pieces made in the "93" design. This work was made before the studio, named Sand, Ash & Bone, split off from 'Roger Thomas Glass', and was subsequently closed. After '94, pieces in this series were signed "Sand, Ash & Bone". Catalogue pages and further product information have been committed to disk storage.
Dichroic glass is glass containing multiple micro-layers of metal oxides which give the glass dichroic optical properties. Dichroic glass was originally developed by NASA and its contractors for use in satellite optics and spacesuit visors. Over time many artists have attempted to develop their own style, one in particular named Roger V. Thomas.
Years of educated experimentation lead Thomas to develop his own unique technique, using colors and translucent layers of glass. His works are special, complex and highly prized. Of his important collections, several pieces are on display in key galleries, including the Smithsonian's Renwick Gallery and the Corning museum. He also has other galleries across the country representing him, from Boston to Hawaii. In addition, Thomas gives lectures and hosts showings. Although it is mentioned in his website that his works are only sold in galleries, this platter from the "93 Geometric" series is being offered from a collection by this seller.
Each and every piece of dichroic art glass is unique, with each being sold for several thousand dollars. With the exception of this offering, there does not appear to be one of Thomas' 40 platters from the "93 Geometric" series created in 1992 on the market, making it rare and highly collectible. Platter is displayed in oak shadow box, milk wash stain, making a statement in 1992, lined in a contrasting color.
