<p>[QUOTE="DragonflyWink, post: 497058, member: 111"]There is 'worked' sheet silver overlay that is applied on other materials, but on this piece and its ilk, the silver was applied by electrodeposition and they were advertised and sold as 'silver deposit' - but these pieces can certainly be called 'silver overlay', because it is silver overlaid on glass, ceramic, and other materials that could withstand the plating solution. On the late 19th and early 20th century pieces, more time in the plating 'bath' left a heavy deposit on the flux, thick enough to be engraved and lightly stamped with a mark. Either the entire piece would have coated with a flux and plated, then the design painted on with a resist and the area not under resist was removed, or the design was painted with a flux then only the design would be plated. Later 20th century pieces were done using what were essentially transferred patterns of flux, the amount of silver plating was much thinner and didn't support engraving. The patent referred to in the last Alvin ad posted is for the technique used for the whitish backing on the deposit, improving the original technique that left a dark interior, and the reason they placed those ads is that they purchased the patent in 1895, then the inventor, John Scharling, started his own firm using the patented technique, Alvin took Scharling to court for patent infringement and won.</p><p><br /></p><p>~Cheryl[/QUOTE]</p><p><br /></p>
