How do I date a decanter?

Dating relies on examining the pontil mark on the base, the style of the glass cutting, and any accompanying silver hallmarks. Earlier Victorian examples often feature hand-blown irregularities and polished bottoms. Later pieces from the Edwardian era introduce machine-tooled threads and standardised stopper fittings.

Are stoppers usually original?

Original stoppers are hand-ground to fit an individual decanter neck precisely, meaning replacements often sit unevenly or show slight colour variations. Inspecting the frosted ground portion of the stopper stem reveals whether it shares the same age as the bottle. Collectors prefer matched sets where every stopper bears the corresponding number or grinding marks of the body.

How should I clean antique glass?

Antique glass requires gentle washing in warm water with mild detergent, avoiding sudden temperature changes that can crack heavy crystal. Residue inside old decanters is best cleared using specialist cleaning beads rather than harsh chemicals. Wooden frames and metal mounts should be dusted dry and kept away from direct moisture.
