How do I date an old wine glass?

Dating relies on combining the bowl form, stem construction, and foot shape with known stylistic periods. Eighteenth-century pieces often feature drawn stems and folded feet, whereas Victorian items lean towards heavier, moulded designs. Changes in glass chemistry, such as the introduction of lead crystal, also help narrow down the decade of manufacture when compared against dated examples.

What is an air twist stem?

An air twist is a decorative stem containing spiralling threads of air trapped inside the glass. Makers created these by introducing air bubbles into hot metal before pulling and twisting the stem. This technique required immense skill to maintain even thickness and clarity throughout the finished drinking vessel.

Were these glasses used daily?

Many of these vessels served practical roles at dining tables for wine, ale, and spirits. Sturdier forms like rummers handled robust daily toasts, whilst delicate twist stems suited formal gatherings. Over time, changing social habits and dining customs shifted these functional items into display collections.
