Were these vessels used daily?

Many items served practical daily functions at the dining table, tavern, or bedside, from holding wine and ale to storing condiments. Sturdier pieces like rummers and tankards endured robust everyday handling. More delicate forms, such as air twist wine glasses and sweetmeat vessels, belonged to formal dining and dessert courses. Their survival reflects careful stewardship by generations of owners.

How can I tell an air twist from an opaque twist?

An air twist contains internal thread-like channels of trapped air drawn into spirals within the clear stem. They typically date toward the mid eighteenth century. An opaque twist utilises solid white or coloured glass rods embedded within the stem matrix. These produce a brighter, opaque white ribbon effect that became widespread after about seventeen hundred and sixty.

Why do some glasses have folded feet?

Makers folded the rim of the foot underneath during hot working to add physical weight and structural reinforcement. This technique protected the vulnerable outer edge from chipping during vigorous tavern or dining use. Folded feet serve as a helpful indicator of earlier manufacture, appearing frequently on pieces from the first half of the eighteenth century.
