How does a tantalus lock work?

A metal bar drops across the glass stoppers to prevent removal of the decanters from the wooden base. Turning a key in the integral lock releases this retaining bar. This clever mechanical design allowed hosts to restrict access to expensive spirits while keeping them visible on the sideboard.

What is a cave a liqueur?

A cave a liqueur is the French equivalent of a decanter caddy, usually housed in a portable wooden chest. These lift-lid cases contain fitted cradles for small decanters and matching glasses. Craftsmen often lined the interiors with velvet or silk to protect the delicate glassware during transport.

Are all these caddies fitted with locks?

Not all variations include locking mechanisms, as some pieces function purely as open decanter frames or stands. Open silver-plated stands securely cradle bottles without the overhead locking bar. Both locked and open variants served the same entertaining purpose in the nineteenth and twentieth centuries.

How do I date an oak decanter stand?

Victorian and Edwardian pieces utilise solid oak with robust brass or silver-plated mounts and hand-cut crystal. Later Art Deco iterations incorporate modernist chrome frames and geometric glass. Examining the construction joints, lock types, and glass cutting styles helps determine the exact period of manufacture.
