Understanding Stucco carving (Gach-bori)

What Stucco carving (Gach-bori) is and how it is made

History

Carved stucco is documented in Iran from before Islam and flourished in Seljuk and Ilkhanid mihrabs; it remains an active building craft in restoration and new architecture.

Technique

Plaster is applied in layers and carved while still workable, or cast in moulds; deep undercut work creates layered arabesques and inscriptions.

Collecting and identification

Moisture damage, repainting and replacement sections are typical in historic buildings; removed panels in museums may have unclear building origins.

This guidance is educational only and is not an authentication or valuation service.

General background on the craft, not a statement about any individual object; dates and attributions summarise common positions in the literature and remain under review. Read the full Stucco carving (Gach-bori) entry.

Before you buy: what to inspect

  • Most architectural craft is seen in place; portable panels and tiles are the exception.
  • Look for hand-cut edges and slight variation between pieces.
  • Check tiles and panels for chips, cracks and old mortar or plaster on the back.

Typical materials: gypsum-plaster.

Red flags: copies and 'Persian style' imports

  • Tiles or panels claimed to come from historic buildings (removal may be illegal).
  • Printed or decal-decorated tiles sold as hand-painted or hand-cut work.

A genuine Stucco carving (Gach-bori) piece should come with a named place of making in Iran (often isfahan, yazd, kashan) and a clear statement that it is handmade.

Questions to ask the seller

  • Where does this piece come from?
  • Is it newly made or salvaged?
  • Can it legally be exported?
