What is an opaque twist glass?

An opaque twist glass is a drinking vessel featuring white enamel threads encased within the clear glass stem. These threads are arranged in various spiral patterns formed during manufacture. Such glasses date principally to the Georgian period and were used for serving wine, ale, or cordials.

How do I date a twist stem glass?

Dating relies on examining the bowl shape, foot formation, and the complexity of the internal stem twists. Eighteenth-century examples typically feature hand-blown lead glass with distinct pontil marks on the base. Later lighting pieces incorporate twentieth-century materials like chrome and brass alongside glass elements.

What is the difference between single and double series twists?

A single series twist contains one set of enamel threads running through the stem, often forming a simple spiral. A double series twist incorporates two distinct patterns, such as an outer corkscrew around an inner column of gauze. Double series stems require greater technical skill from the glassmaker.

Are all these items drinking glasses?

While the majority of eighteenth-century pieces function as wine, ale, or cordial glasses, the selection also includes domestic lighting. Table lamps from the Art Deco and Edwardian eras utilise twisted stem designs in chrome and opaline. This broadens the category from dining tableware to interior illumination.
