A tantalus is a locked wooden frame designed to hold crystal decanters securely while leaving the contents visible to guests. The locking mechanism prevents servants or guests from pouring unauthorized drinks. These pieces typically combine oak or coromandel wood with silver plated mounts and sturdy locks, dating predominantly to the Victorian and Edwardian periods.

How do decanter labels attach?

Decanter labels hang around the neck of a bottle by means of a fine silver link chain or a rigid metal collar. They are sized to fit snugly against the shoulder of the decanter. Most examples identify specific spirits such as madeira, sherry, rum, or gin, helping hosts distinguish between similar decanted liquids.

What glass colours appear?

Spirit bottles and decanters appear in clear cut crystal alongside coloured glass variants in ruby and green tones. These coloured glass pieces were often housed in silver plated stands or fitted with hallmarked silver collars. Matching sets sometimes included matching glasses alongside the central liquor bottle.

How are periods identified?

Periods are identified through a combination of silver hallmarks, stylistic design traits, and manufacturing techniques. Georgian pieces show specific maker marks and hand-engraved titles, while Edwardian and Art Deco items reflect later decorative trends. Wood types in tantalus sets and the depth of glass cutting also provide clues to the exact decade of production.
