The lost wax process was invented by and for art founders several thousands of years before Christ, in EGYPT and even SUMERIA ! The fact is that this lost wax process allows, from an artist's model, the duplication of the delicate forms of jewels and goldsmith's pieces, all kinds of ornamental pieces (lightning, furniture) as well as statuettes and art statues with a maximum respect of the initial artist's model. In this way, with a plaster block-mould process quite similar to the one used in the industry, one can produce jewels of a few millimetres in diameter just as easily as one metre tall statues made of copper base (bronze, brass) alloys or made of precious metal alloys such as gold or silver. If in the jewellery and goldsmith fields, this plaster block-mould is universally used, in artistic foundry, the processes used are more wide-ranging. Effectively, the sizes of statues and artistic castings can range between 10 centimetres and 2/3 metres, at least for pieces produced with the lost wax process. As in the industrial field, the block mould process is used for small pieces and the shell process for the biggest statues. Between the two processes, there is the so-called "Traditional Process", in which a plaster based investment is simply thrown on the wax pattern until it is completely covered by a thick layer. This will be used as casting mould, once it is fired and once the wax is melted out. |
