What is an opaque twist wine glass?

An opaque twist wine glass is an eighteenth-century drinking vessel with a stem enclosing white enamel threads. These threads form spirals, gauzes, or cables inside clear lead glass. Craftsmen produced them primarily during the mid-Georgian period by manipulating molten glass rods before the metal cooled. They represent a significant stylistic shift from earlier heavy baluster stems.

What is the difference between single and double series?

A single series stem contains just one set of twisted elements, such as a pair of opaque white spiral threads running down the centre. The effect is clean and restrained. Double series stems combine two distinct twists within the same rod, often pairing an outer white enamel spiral with an inner gauze or secondary corkscrew. This creates a denser, more complex visual texture inside the clear metal.

Were these glasses used for wine?

Georgian drinking glasses served various beverages depending on their capacity and bowl shape. While many held wine, smaller vessels functioned as cordial or sweetmeat glasses for liqueurs and rich desserts. Ale glasses and champagne glasses also appear in the period, featuring taller narrow bowls or specific flute-moulded designs suited to their contents.
