Are eighteenth-century wine glasses safe for use?

Many collectors use eighteenth-century glasses for special occasions, provided the glass is free from structural cracks or unstable repairs. Hand-washing is mandatory for these fragile pieces to preserve the historic metal. Inspect the rim and foot carefully for microscopic chips before pouring. Modern dining settings suit these glasses well when handled with due care.

How do I distinguish air twists from opaque twists?

Air twists appear as fine, spiralling threads of trapped air inside the clear stem of a glass, created by drawing bubbles during the blowing process. Opaque twists utilise solid white or coloured glass rods embedded within the clear metal. Examining the stem under good lighting reveals the solid nature of opaque threads compared to the hollow air channels of an air twist.

Victorian examples tend to be heavier, utilising brilliant-cut crystal with deeper facets and more elaborate star-cut bases. Stylistic shifts reflect the industrial advancements in glass cutting and pressing during the nineteenth century.
