Sterling Silver

Sterling Silver is 92.5% silver and 7.5% copper. We use a slightly higher silver content to improve quality. The metal is supplied as grain, which we melt at around 960 degrees Celsius.

The process is more complex than pewter casting as the mould can only be used once. Hence the term, “lost wax process”. A solid plaster mould is made around a “tree” of wax models. The wax is melted out and then silver is poured into the mould. Once solidified, the mould is broken apart to extract the metal castings which are then filed, sanded and polished individually.

The Glas Mor collection is very special.  Each piece is inlaid with a paste containing tiny grains of coloured glass. The item is then heated in an oven to melt the glass. This creates beautiful  vitreous enamel colours.

Our favourite is blue-green, just like the sea nearby.
