How do you open a tantalus without a key?

Most antique tantaluses require the original key to lift the locking arm and release the decanters from the frame. Forcing the mechanism risks damaging the surrounding wood and brass mounts. Professional locksmiths can sometimes pick or fit a replacement key to the original lock without altering the timber housing.

What is the difference between a tantalus and a decanter box?

A tantalus exposes the bodies of the cut crystal decanters behind a locking metal bar fitted across their necks. This allows guests to view the contents while keeping the spirits secure. A decanter box, such as a coromandel or brass-mounted case, completely encloses the bottles within hinged wooden lids and doors for concealed storage.

Are replacement stoppers acceptable on Victorian decanters?

Original stoppers that match the cut pattern and internal wear of the decanter neck remain the preference for collectors. Replacement stoppers are common due to breakage over decades of use. Inspect the ground glass seating inside the bottle neck to ensure any replacement sits flush and airtight.
