Champlevé is a decorative technique used in metalworking, particularly in enameling. It involves carving or etching a design into a metal surface, then filling the resulting recesses with enamel. The enamel is then fired in a kiln to create a durable and colorful surface. Champlevé was popular in medieval Europe and is still used today in jewelry making and other decorative arts.
