Were crystal air twist glasses used daily?

In the eighteenth century, such glasses served dining tables for wine, ale, and cordials during formal meals and social gatherings. Their heavy lead content made them durable enough for regular use by affluent households. Today, collectors often use them on special occasions or display them to appreciate the optical effects within the stems.

What is a Jacobite engraved glass?

Jacobite glasses feature covert symbols, such as roses and oak leaves, used by supporters of the exiled House of Stuart during the eighteenth century. Engravers added these motifs to toast the restoration of the monarchy in secret. Such pieces are particularly sought after by collectors for their historical association and detailed diamond-point or wheel engraving.

How can I tell an 18th-century glass from a later copy?

Eighteenth-century pieces typically exhibit tiny surface wear marks on the underside of the foot, known as pontil scars or wear, alongside slight asymmetries from hand-blowing. The lead crystal often displays a slightly warmer tone and exceptional refractive clarity. Twentieth-century revivals, such as those from the nineteen-thirties, usually show more uniformity in manufacture and lack the characteristic wear of early table use.
