Qalamzani: Persian Metal Engraving and Chasing

How does a qalamzani piece get made?

The vessel or tray is first raised or spun, then filled with a warm pitch compound that hardens and supports the metal from behind. Without that backing, every hammer blow would simply deform the whole object.

The engraver transfers the design and outlines it with a tracing punch, then works inward: sinking backgrounds, modelling figures and finally texturing. A master typically owns dozens of punches, each ground to a different footprint, and the tonal richness of a good piece comes from that vocabulary rather than from any single tool.

The pitch is melted out and the piece is cleaned. Backgrounds are often darkened with an oxidising treatment so the raised design stands out, and the highlights are then polished back by hand.

• Chasing works from the front; repoussé pushes from the back for deeper relief. Most Persian work combines both.
• Silver takes finer detail; copper is more forgiving and traditionally more common for large trays.
• Motifs run from Safavid arabesque and hunting scenes to Achaemenid-revival friezes and calligraphic bands.

Where does qalamzani sit in Iranian art history?

Worked metal is one of the oldest continuous Iranian arts, with Sassanid silver vessels among the best-known ancient examples in world museums. The punch-worked decorative idiom that survives commercially today was consolidated in the Safavid period and refined through the Qajar era.

Isfahan remains the hub, where qalamzani is practised alongside mina kari enamel and firoozeh-koobi. Engraved blanks are also frequently made for enamelling, so the two crafts share workshops and suppliers.

How do you judge quality in engraved metalwork?

Machine-stamped and acid-etched trays are sold widely as hand engraving. The difference shows in the surface, not in the motif.

• Hand work varies: repeated leaves differ slightly in depth and angle. Stamped work is identical every time.
• Run a fingertip over the back. Chased and repoussé work leaves a corresponding topography behind the design.
• Acid etching gives soft, rounded, shallow edges with no tool marks; punch work leaves crisp facets.
• Look at background texture — dense, even matting punched dot by dot is slow and is a mark of serious work.
• Deep relief on thin sheet risks splitting, so a heavy gauge with high relief signals a confident maker.

Living with copper, brass and silver

These metals are meant to be handled, but each patinates in its own way and over-cleaning destroys the contrast the engraver built in.

• Do not polish the recessed dark backgrounds away; clean the raised highlights only.
• Avoid abrasive metal polish on oxidised areas; a soft dry cloth is usually enough.
• Tinned copper used for serving needs re-tinning periodically by a specialist.
• Store silver with anti-tarnish strips and away from rubber and wool.
