How do I clean an old decanter?

Wash the interior carefully using warm water and non-abrasive cleaning beads rather than harsh detergents. Avoid sudden temperature changes to prevent cracking the heavy lead crystal. Dry the vessel thoroughly upside down on a linen cloth and store the stopper separately to allow air circulation inside.

Can I store alcohol in them permanently?

Spirits and wine can be kept in these vessels for moderate periods, though very long storage may cause evaporation or lead leaching. Empty and rinse the container periodically if contents remain unconsumed for many months to preserve the glass.

How do I date a glass decanter?

Examine the base for pontil marks, neck ring styles, and the sharpness of the wheel cutting. Georgian pieces often display kick-up bases and applied rings, while Victorian and Edwardian examples show machine-polished facets. Engraved labels and stylistic cues like Sheraton or Arts and Crafts motifs further narrow down the decade of production.

Are original stoppers important?

Original stoppers that match the cut and colour of the body maintain the integrity and visual harmony of the piece. Replacements are common due to breakage over centuries of domestic use. Inspect the ground glass peg and interior neck for matching factory numbers to confirm the stopper belongs to the vessel.
