No two plates are alike. The art of enameling began with the age of the discovery of glass. Enameled pieces, which decorated Egyptian, Mesopotamian and Persian buildings, are still in existence. Bracelets, silver and other objects to which enamel was applied, appeared in tombs of the millennium, dating from the centuries III b.c. to VII a.d. In Coimbra, Portugal, artistic enameling is much appreciated by those who acquire pieces.
Private collections exist in various parts of the world.
