Chennai Handloom & Bronze Craft
Temple bronzes and Kanchi-tradition silks, traded through the Coromandel capital.
Chennai and its hinterland in northern Tamil Nadu bring together two prestige crafts through the city's role as a commercial and cultural gateway. Sthapati families, especially at Swamimalai near Kumbakonam, cast solid bronze images of Hindu deities by the lost-wax method following the proportions of the Shilpa Shastras, continuing the tradition of the great Chola bronzes. Chennai itself is a major centre for the trade, finishing, display and export of Kanchipuram and other South Indian silk sarees, and the base for the state's craft institutions.

Process Steps
Modelling the wax image
The deity is sculpted in beeswax following the measurements and postures set out in the shilpa texts.
Investing the model
The wax figure is coated in layers of fine clay, sand and charred husk and dried to form a solid one-piece mould.
Burning out the wax
The mould is heated so the wax melts and drains away, leaving a cavity in the exact shape of the image.
Casting the bronze
Molten pancha-loha is poured into the pre-heated mould in a single pour and left to solidify.
Breaking out and chasing
The mould is broken open, and the rough casting is filed, and its ornament, features and attributes are chased and engraved.
Finishing and consecration
The icon is polished, its eyes and sacred marks completed, and it is ritually consecrated for worship.
Weaving the silk (parallel craft)
For the textile trade, heavy silk is reeled, dyed, warped and woven into sarees with interlocked contrast borders and zari pallus.

Did You Know?
A traditional temple bronze is cast in a mould that is destroyed to release it, so every processional icon of a deity is, technically, unique and unrepeatable.
Every craft has a story. Every story begins with tradition.
