How do I clean antique wine glasses?

Wash them gently by hand in warm, soapy water without harsh abrasives or soaking them for prolonged periods. Dry them immediately with a soft linen cloth to prevent water spots. Avoid placing these historic pieces in a modern dishwasher, as the high heat and harsh detergents will cloud the lead glass permanently.

What is the difference between air twist and opaque twist stems?

Air twist stems contain fine trapped air channels drawn into spirals within the clear glass. They produce a subtle, transparent internal pattern. Opaque twists incorporate white or coloured enamel rods inside the clear metal, creating solid, highly visible threads that stand out clearly against the light.

Can I still drink wine from eighteenth-century glasses?

Many collectors enjoy using their antique stemware for special occasions, appreciating the tactile weight and historical connection. The lead glass is durable enough for careful use. Exercise caution with extreme temperature changes, such as pouring hot liquids into cold glass, to prevent thermal shock and cracking.

How do I date an antique glass without a maker's mark?

Dating relies upon analysing the bowl form, stem construction, foot style, and manufacturing characteristics. Eighteenth-century pieces often feature pontil marks, thick lead metal, and specific knop configurations. Comparing the silhouette and engraving style against documented examples helps narrow down the production era to specific decades like the seventeen-seventies or eighteen-twenties.
