Flash glass is a two-layer material made by fusing a thin skin of coloured glass over a clear or contrasting crystal base. This method allows artisans to cut through the outer stratum to create patterned designs. Craftsmen remove portions of the surface colour by wheel-engraving, etching, or cutting, leaving bright patterns that contrast sharply with the base material.

How do I clean antique flash glass?

Wash these pieces gently by hand using lukewarm water and mild soap. Avoid abrasive sponges or harsh detergents that can scratch the surface or damage gilding. Dry them immediately with a soft cloth to prevent water spots, particularly around engraved channels and gilded rims where moisture might linger.

How can I tell Bohemian pieces apart?

Bohemian items frequently display deep ruby red colouration paired with heavy gilding, frosted panels, and detailed etching. They often take the form of vases, centrepiece bowls, and chandelier components. English equivalents tend to focus on functional tableware such as decanters, carafes, and cruet sets, often utilising cranberry or green over crystal.

Can I use these decanters daily?

These decanters and carafes are sturdy enough for occasional service, though many collectors prefer to display them. Hand-washing is essential to preserve the exterior decoration. Care should be taken with pieces featuring gold leaf or delicate surface engraving, as modern dishwashers will quickly ruin the finish.
