The birthplace of Mannar's cottage industry is the family. Only a few hundred families are involved in the trade, and secrets, skills, figures & calculations of the lost wax process are passed from one generation to the next…
This is how the last wax process goes: It start with a clay core covered by a layer of soft wax on which the intricate details are delicately sculptured. The wax model is then covered by layers of fine clay.
Drain ducts are left for the wax, which melts away when the clay is baked, thus creating a mould for the metal.
The hot moulten metal is poured in and hardens between the clay core and mould, taking the shape of wax.
