A tantalus is a locking wooden stand that secures decanters by trapping their glass stoppers beneath a metal bar. This design allowed hosts to display fine spirits while preventing unauthorised access by household staff. Most examples date from the Victorian and Edwardian periods, constructed in oak or mahogany with brass mounts and working locks. The bottles can only be removed once the locking arm is unlocked with a key.

How do I date an antique decanter?

Dating relies on the shape of the bottle, the depth and style of the glass cutting, and any associated metalwork. Georgian decanters often feature three rings on the neck and deep slice-cutting, while Edwardian versions frequently appear in fitted oak tantali. Silver-plated or sterling silver labels and mounts provide crucial clues through hallmarking stamps. Examining the pontil mark on the base of the glass also helps determine whether the piece was hand-blown in the nineteenth century.

What is a cave a liqueur?

A cave a liqueur is a portable French box or casket designed to hold a set of matching decanters and cordial glasses. These luxury items were popular during the nineteenth century under Napoleon III. The interiors feature velvet or silk-lined fitted compartments that cradle the glassware securely. They were used in formal drawing rooms for serving after-dinner liqueurs to guests.
