Category : Glass
Sub Categories : Art Glass, English, Stevens & Williams
A beautiful Stevens and Williams Silveria vase 4"h 3 1/2"w.signed. No chips, nicks etc. One spot of oxidation as seen in photo. Silveria was developed in 1900 by John Northwood II, an employee of Williams and Stevens. The process of casing silver foil between two layers of colorless glass. The silver foil was protected from exposure to oxygen and thereby prevented the unfortunate and otherwise inevitable phenomenon of tarnish by being cased between these layers of glass. It required the glassmaker to apply the silver foil to a fully-expanded clear glass bubble that already approximated the size of the intended article. After applying the second layer of colorless glass over the foil no further expansion of the glass was required. For this reason the foil did not split into small fragments as seen in the ware of other manufacturers. After casing the foil the glassmaker applied crushed glass colors to the surface of the bubble, typically in soft shades of pink, blue, yellow and green. Seen against the shimmering silver-foil background, the visual effect closely resembles iridescence. Next the glassmaker ornamented the bubble with freely-applied green threading and finally shaped the article to its finished form. Production of Silveria was discontinued after just a few years.

846 : Thomas Webb & Sons Bronze Crackle Vase Thomas Webb $750.00
Category : Glass
Sub Categories : Art Glass, English, Swords
This spectacular vase is Bronze glass by Thomas Webb & Sons ca. 1875 - 1885. The special process to achieve the finish is similar to the Stevens & Williams process to make their spectacular Moss Agate. Each formula was immersed in cold water to achieve the thermal shock crackle, then each was reheated, but where the Stevens was then cased twice to fill in the voids for a smooth finish, the Webb is blown again to pucker the surface with the addition of the final layer.*** FOR THE ADVANCED COLLECTOR - WITH A HIGH INTENSITY LIGHT, THE BASE SHOWS A DEEP EMERALD GREEN, WHICH IS THE ONLY LEGITIMATE COLOR THAT WEBB PRODUCED IN THIS SPECIAL FORMULA!!!
