Enamel is usually used to design vase, jewelry and candleholder in addition to doors and chandeliers of holy shrines. The central city of Isfahan is the most important Iranian hub of enameling.
Enamel working and decorating metals with colorful and baked coats is one of the distinguished courses of art in Isfahan.
Mina, is defined as some sort of glasslike 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 used by painters, goldsmiths and metal engravers since long times ago.
The artisans engrave the surface of the metal with intricate designs using a metal stylus which is then filled in with colors.
Mina is then placed in a furnace where the colors are fused and hardened to become one with the surface.
The piece is then gently rubbed with a file and cleaned with a mixture of lemon and tamarind that helps highlight the luster of each color.
