Mina Kari: Persian Enamel on Metal

How is mina kari made, step by step?

A coppersmith first raises the blank — a plate, bowl, vase or box — by hammering sheet copper over stakes. The form has to be even, because any thin spot will warp in the kiln.

The blank is cleaned and coated with a white enamel ground, then fired. That ground is applied and fired several times until it is dense and free of pinholes; this stage decides whether the finished colours will look luminous or muddy.

A painter then works over the white ground with mineral oxide pigments, usually a fine brush and freehand arabesque, floral or bird motifs. The piece returns to the kiln after painting, sometimes more than once, so the pigments vitrify into the ground rather than sitting on it.

Gold outlines or gilded rims may be added last. Because every firing risks cracking, a large plate that survives with even colour represents a real success-rate problem for the workshop, not just labour time.

Where does mina kari come from?

Enamelling on metal is ancient and widely distributed, with early Iranian examples associated with Achaemenid and Sassanid metalwork. The tradition that shaped what is sold today, however, is closely tied to Isfahan and to the Safavid and Qajar workshops that supplied court and shrine.

Isfahan's Naqsh-e Jahan square remains the commercial centre of the craft, and mina kari is routinely grouped with qalamzani engraving and firoozeh-koobi turquoise inlay as the three metal crafts most identified with the city.

What separates good mina kari from tourist work?

Price differences in the bazaar are enormous, and almost all of them come down to whether the decoration is fired glass painted by hand or a decal printed onto a coated blank.

• Hold the piece to raking light: hand painting shows brush direction and tiny irregularities between repeated motifs; a decal repeats perfectly.
• Look for a glassy, slightly uneven surface with depth. A flat plastic sheen usually means lacquer, not enamel.
• Check the underside and rim for enamel coverage and for burn marks from clumsy firing.
• Pinholes, grey patches and crazing in the white ground indicate a rushed base stage.
• Weight matters — thin, light copper dents easily and is a sign of a cheap blank.

How do you care for enamelled metal?

Enamel is glass on metal: hard but brittle, and vulnerable to shock rather than to wear.

• Never put it in a dishwasher and do not soak it.
• Wipe with a soft damp cloth and dry immediately; skip abrasive creams and ammonia cleaners.
• Display decorative plates on padded stands — a knock on a rim chips enamel down to the copper.
• Use enamelled bowls for dry goods rather than acidic food unless the maker states the piece is food-safe.
