How do I clean the silver without damaging the glass?

Use a soft cloth and a gentle, non-abrasive silver polish, taking care to avoid getting chemicals on the glass surface or inside any liners. For pieces with glued or fitted metal mounts, avoid total immersion in water to protect adhesives and internal seals.

Are glass liners original to the silver pots?

Many mustard pots and baskets retain their original coloured or clear glass liners, which were shaped specifically for each mount. Replacements do occur, so check that the glass sits flush within the silver rim without excessive movement.

What periods do these vessels come from?

The pieces span from the mid-nineteenth century Victorian era through Edwardian times, the Art Nouveau period, and into the mid-twentieth century. Stylistic cues such as heavy casting, floral piercing, or geometric Art Deco lines help identify the specific era of manufacture.

How can I tell sterling silver from silver plate?

Sterling items generally bear hallmarks indicating the standard of purity, the maker, and the assay office where the metal was tested. Silver-plated pieces typically show marks denoting electroplate or bear different manufacturer stamps without standard sterling hallmarks.
