Stevens and Williams Victorian Glass Bowl and Undertray Threaded Cranberry Glass

Lovely 19th century hand blown threaded cranberry glass bowl and undertray measuring 6 1/2" diameter. It was possibly made by Stevens and Williams from England or the New England Glass company from Sandwich, Mass. The threaded section is an amber and is in very good condition with no missing sections. Both pieces have a polished pontil and a very nicely ruffled form. Threaded glass was very popular in the late 1800's to early 1900's and was done by actually wrapping a molten piece of glass around the formed body. Many well known glass companies used this process later on especially when you think of Art Nouveau lighting from the early 1900's and the art glass of Tiffany, Quezal, Durand, Loetz and other top companies that all used this technique in the lamp shades and vases. even dinnerware by Fry and Steuben. This was a tedious and difficult process and many pieces fractured before completion for the simple reason that when hot glass is added to the surface of glass that is cooling down, it can easily crack. The ruby color of the glass was formed by adding a slight amount of gold to the glass formula and this would cause the cranberry color to form when heated. This is true of most cranberry or ruby glass - the added gold is what causes the red or pink color. This bowl and undertray are in excellent condition especially considering that they are over 100 years old. PG5
