Dhokra casting uses the lost-wax method that has shaped Indian metal figures for over four thousand years

the gist

Dhokra is a non-ferrous metal casting tradition from India that uses the lost-wax technique and has been practised for more than 4,000 years. The process starts with a clay core shaped like the final object, which is covered in a layer of wax, usually beeswax mixed with resin and nut oil. The artisan carves the fine details into the wax and then covers it with clay. When the clay is fired, the wax melts out through drain ducts, leaving a hollow mould, which is filled with molten metal, often brass scrap. Once the metal hardens, the outer clay is chipped away and the figure is polished. Dhokra horses, elephants, peacocks and owls are prized for their simple form and folk motifs, and the technique has also been found in China, Egypt, Nigeria and Central America.

how it works

The wax model is the sacrificial part: once the clay mould is fired, the wax melts and drains away, leaving a cavity of exactly the same shape. Molten metal fills the space and takes the detail of the original carving. The clay core keeps the object hollow, which saves metal.

so what

Dhokra shows how a single ancient casting method has spread across cultures and remained in use. The craft also supports living artisan communities, whose products are sought in India and abroad.

fun fact

One of the earliest known lost-wax objects is the Dancing Girl figure from Mohenjo-daro in the Indus Valley.
