What are opaque twist glasses?

Opaque twist glasses are drinking vessels featuring stems filled with white enamel glass threads enclosed in clear lead crystal. They date chiefly from the eighteenth century. These pieces served as wine, ale, and cordial glasses during the Georgian era, replacing earlier air twist designs.

How do you date an opaque twist glass?

Dating relies on stylistic clues including bowl shapes, foot formations, and the complexity of the internal enamel threads. Eighteenth-century examples generally display lighter metal and specific foot profiles. Later nineteenth-century pieces often reveal differences in crystal weight, colour tone, and manufacturing technique compared to their Georgian predecessors.

Were these glasses used for drinking wine?

Yes, the majority of surviving examples functioned as wine glasses, alongside variants made for ale, champagne, and cordials. Their capacities were generally smaller than modern wine glasses. Specialised forms like sweetmeat glasses held confectionery, while firing glasses were designed for toast-drinking rituals.

What is the difference between single and double series?

Single series twists contain a single pair of enamel threads, whereas double series incorporate two distinct sets of threads twisted around each other. Triple series examples feature even more complex internal arrangements. More intricate twist configurations generally require greater skill from the glassmaker.
