Enamel working and decorating metals with colorful and baked coats are one of the distinguished artwork in Isfahan. Mina, is defined as some sort of glass-like colored coat which can be stabilized by heat on different metals particularly copper.
Although this course is of abundant use industrially for producing metal and hygienic dishes, it has been paid high attention by painters, goldsmiths and metal engravers since a long time. It is categorized as enamel painting, charkhaneh (or chess-like enamel) and cavity enamel.
Enamel painting is practiced in Isfahan and specimens are kept in the museums of Iran and abroad, indicting that Iranian artists have been interested in this art and used it in their metalwork ever since the rule of Achaemenian and Sassanid dynasties. Since enamels are delicate, we do not have many of them left from ancient times. Most of the enameled dishes related to the past belong to the Qajar dynasty during 1810–90.
