Offered is this rare, Stevens & Williams 'Osiris' glass vase, designed by John Northwood I (when he was at S & W) and made around 1887 - 'Osiris', 'Silveria' and 'cameo' are the most desirable of S & W glass products. Made on three-cased-layers, the vase is 13 inches (33 cm) tall and 6 1/4 inches (16 cm) wide at its widest - it is extremely rare to come across such a large 'Osiris' vase in the marketplace. Excellent condition (there is a bump, which occurred during fabrication, on the inside-part of the vase - see 8th picture). Polished pontil. Unsigned. An 'Osiris' ewer is shown on page 189 of Ray & Lee Grover's book, 'Art Glass Nouveau' (shown in last picture here for your convenience). Additionally, S & W's 'Osiris' glass objects are shown on page 281 of Charles Hajdamach's book, 'British Glass 1800-1914'.
