The art of enamelling is an ancient one. The process involves heating powdered glass and flooding a chamber with raised edges. Items with enamelled decoration survive in museums and private collections alike and those that hit the auction market regularly surpass their estimates.
In the Edwardian era enamelled items were very popular, with the decoration appearing on objects and jewellery alike. Lot 4 in the Jewellery Auction on 29 August is a modern enamelled brooch and earring set estimated at £50–100.
