What is a mantel lustre?

A mantel lustre is a decorative glass vase fitted with a removable rim that suspends cut crystal prisms. They were designed to sit on fireplace mantels, where the hanging prisms would glitter in the candlelight and gaslight of nineteenth-century rooms. Most examples are found in pairs, serving as formal garniture alongside clocks or candelabra. The design allows light to bounce through the room while displaying rich colours like ruby red, cobalt blue, and forest green.

How do I clean a crystal vase?

Cleaning these nineteenth-century vessels requires lukewarm water and mild soap, avoiding harsh chemicals or sudden temperature changes. Old crystal and coloured glass can crack under thermal shock, so water must remain comfortable to the touch throughout. Prisms on lustres should be washed individually and dried with a soft lint-free cloth before reattaching them with their original wire or thread. Metal mounts, gold leaf, and enamel work need careful handling to prevent any rubbing or moisture damage.

Flash glass is a method where a gather of clear or white glass is dipped into a pot of molten coloured glass, creating a thin outer skin. When the glassblower cuts facets into the surface, the clear body shows through in sharp contrast to the saturated colour. This technique provided the intense ruby, green, and cranberry hues seen on Victorian lustres without making the entire vessel from heavy, costly coloured batch. It allowed makers to achieve precise depth and brilliance in cut patterns.

Where did these pieces originate?

These decorative glass objects come from several major European manufacturing centres active during the nineteenth century. English makers in Stourbridge and London produced fine engraved vases and lily vessels, while Bohemian workshops specialised in heavy overlay glass and flash lustres. French makers contributed opaline glass and gilt bronze mounted centrepieces. Trade and international exhibitions spread these styles widely across homes in Britain and beyond.
