How do you open a locking glass tantalus?

A key turns in the lock to release the metal retaining bar, allowing it to pivot or lift away from the necks of the decanters. Once the bar clears the glass stoppers, individual bottles can be lifted from their fitted bases. Without the key, the mechanism remains securely locked over the stoppers, preventing the decanters from being removed from the wooden frame.

What periods do these pieces come from?

Most surviving examples date from the Victorian and Edwardian eras, spanning the late nineteenth and early twentieth centuries. Production continued into the Art Deco period of the 1930s with streamlined designs. Earlier pieces typically feature heavy oak and brass mounts, while later twentieth century versions adopt geometric metalwork and simplified wood housings.

Were these used in dining rooms?

These pieces functioned primarily as after dinner barware, placed on sideboards or tables in reception rooms for entertaining guests. The locking mechanism allowed hosts to control access to spirits. Some versions integrated games compendiums, serving a dual purpose for evening gatherings and social pastimes in domestic interiors.

Are the decanters original to the case?

Many pieces retain their original cut glass or crystal decanters, often shaped specifically to fit the contours of the wooden base and locking bar. Matching patterns and stoppers indicate an intact set. Replacement decanters occur frequently due to accidental breakage over time, making the match between the glass and the locking geometry an important consideration.
