Vintage 1920s Oroplastic Etched Glass Mayonnaise Bowl Greek Nude Figures Moser Walther

This is a gorgeous pressed glass bowl with under plate that are deeply etched in the oroplastic technique with neo-classical Greek nude figures with Greek key border. The oroplastic technique was developed by Leo Moser around 1914 or 1915 and involved deep etching using acid and then gilding the etched area. During the 1920s, a few other glass makers, such as Loetz, Carl Goldberg, Walther & Sohne and Oertel adopted the technique. This piece is not signed, so it is difficult to attribute, but my best guess would be Moser, possibly Walther & Sohne. The bowl is made of two part molded clear glass while the plate is a single piece. The bowl is cut on its side with a floral and leaf design. The etched rims have a blue colour that is fired onto the underside while the topside is gilded in gold, so that the figures pop out in blue against the gold background. Please note that in some of the photos that the piece was backlit for clarity, so only the blue colour shows and the gold was washed out by the lighting, only in the photo, not in real life. I believe that the bowl is meant to be a mayonnaise, but really much too beautiful to be used for that purpose. It measures 4 1/2 in height with a top of diameter of 6 5/8 while the under plate has a diameter of 8 - the set weighs 2 lbs and 3 oz. It is in very good condition with no chips or cracks - some slight wear to the gilding, but, in general, displays very well. The glass is fairly thick yet has very good clarity.
This is a beautiful piece of art deco glass - very nice quality and lovely decoration!
