1.Clay Models After final touches and refinements, the clay models are ready for the foundry.
2.Wax Room Once the moulds have been made of the original clay scul- ptures, the molds are lined with a thin coat of wax.
4.Shell Room The waxes are then dipped into a liquid slurry which dries like a ceramic, thus creating a hard shell containing the waxes.
5.Burnout The shells are then heated, causing the wax to melt and exit the shells (the “lost wax” process).
6.Metal Pouring Molten bronze (1900-2100 degrees) is now poured into shells and left to cool.
7.Breakout Once the shells have cooled, they are hammered off the bronze and any remaing shell fragments are ground off the metal.
8.Sand Blasting The bronze is now sand- blasted to remove remaining shell fragments.
9.Welding The various chunks are welded together.
10.Metal Chasing The weld lines are now ground away, so that the sur- face of the bronze is nice and smooth.
3.Wax Check The wax is then removed from the molds, checked for accu- racy, and the surfaces are refined, if necessary.
11.Final Patina It is now ready to go to the patina shop for final coloration.

The Foundry Process

A Long Journey from Clay to Bronze
It is not only the cost of bronze that makes sculpture so expensive.  It’s also the labour.  Frequently people don’t realize what a lengthy, labour-intensive process it is. Read more....
