Champleve is an enamelling technique used mainly in the decorative arts. In this process troughs or cavities are cut or cast into a metal plate. The depressions are then filled with enamel and the object is then fired in a kiln until the enamel has hardened. Once cooled the object is filed down and smoothed with a pumice stone and finally polished.
It is a process similar to cloisonné but gives greater irregularity in the metal lines which form the pattern. In watch making Champleve is used to decorate dials and cases.
