How do I identify a cut to clear glass?

Look closely at the surface facets where the coloured glass has been carved away to expose the transparent layer underneath. Running a finger across the design will reveal distinct tactile edges between the coloured exterior and the clear crystal. Heavier weight and sharp, precise geometric cuts typically indicate genuine layered crystal rather than surface-stained or painted alternatives.

What periods are these glasses from?

The pieces seen here date primarily from the nineteenth and early twentieth centuries, spanning the Victorian era through Art Deco styles. Victorian and Bohemian examples often feature rich cranberry or cobalt hues with deep panel cutting. Later twentieth-century works from makers such as Val St. Lambert bring cleaner modernist lines while maintaining the traditional cased glass technique.

How were these glasses used originally?

Many of these items served functional roles at the dining table, including wine glasses, champagne flutes, decanters, and water carafes. Coloured hock glasses were particularly popular for serving specific vintages during formal Victorian and Edwardian dinners. Larger forms like baskets, vases, and tazzas functioned as decorative centrepieces or scent bottle containers for drawing rooms and dressing tables.

How should I clean and care for them?

Wash these items gently by hand using lukewarm water and mild detergent, avoiding harsh scrubbers that might scratch the surface or wear any gilt highlights. Placing them in a modern dishwasher can cause thermal shock and permanent clouding to older crystal. Dry them immediately with a lint-free cloth to maintain the brilliance of the faceted crystal and prevent water spots from forming on the polished surface.
