What is an air twist stem?

An air twist is a decorative stem featuring internal spiral channels filled with elongated air bubbles. Glassmakers created these by puncturing a heated lump of metal and twisting the glass as it was drawn out. These delicate internal threads catch the light differently depending on the angle of view. They represent a signature achievement of mid-eighteenth-century English glasshouses.

Can I drink from these glasses?

Many people enjoy using these antique vessels for special occasions, provided the glass is handled with extreme care. Lead glass is stable for holding liquids during normal dining use. However, because of their age and historic value, hand washing is mandatory after use. Storage should keep them away from vibrations and crowded shelf edges.

How do I date a wine glass?

Dating relies on combining the form of the bowl, the construction of the stem, and the shape of the foot. Plain stems and heavy balusters generally point to the first half of the century, while twist stems belong to the middle decades. Foot styles also offer clues, as folded feet appear more frequently on earlier pieces. Comparing the overall weight and metal clarity helps narrow the period further.
