❖ It is also called investment casting.

❖ It is one of the oldest but by no means simplest casting processes.

❖ While the direct lost-wax method was capable of casting models of great delicacy and complexity.

❖ It so named because a wax pattern of a restoration is invested in a ceramic material then the pattern is burned out to create a space into which molten metal is placed or cast.

Answer 2

Lost wax' technique was used to make Chola bronze statues. This technique involved several stages:

First of all an image was made of wax.

This was covered with clay and left in sun to dry.

It was then heated and a small hole was made in the clay cover. The molten wax was drained out through this hole.

Then molten metal was poured into the clay mould through the hole. Once the metal cooled and solidified, the clay cover was carefully removed and the image was cleaned and polished.

The ‘lost wax’ technique had the following advantages :

1. It was a quick way to make statues.

2. Wax was a reusable material.

3. Statues of any desired shape could be produced quickly through this technique.

4. The Bronze statues were not at all hollow from inside. They were solidified and had long life.
