Can I drink wine from an 18th century glass?

These vessels were originally made for dining and imbibing, so they remain fully capable of holding wine today. Exercise caution when handling such fragile antique lead glass to preserve its structural integrity for future generations.

What is the difference between air and opaque twists?

Air twists contain actual threads of trapped air enclosed within the transparent body of the glass stem. Opaque twists incorporate solid white or coloured enamel glass rods into the molten metal to achieve a similar spiralling pattern.

How can I tell a Georgian air twist from a later copy?

Examine the foot of the vessel for tool marks, pontil scars, and the soft wear patterns characteristic of age. Georgian lead glass also exhibits a distinctive greyish-blue refraction and exceptional material weight compared to modern reproductions.
