The sprueded wax is prepared for shell.
The wax is dipped in a liquid called slurry.
The excess liquid is allowed to drain off.
A fine layer of sand is shaken over the entire piece. This will bond with the slurry to create a layer of shell. This initial coating is fine enough to register the detail in fingerprints. As progressive coats of the slurry/sand combination are applied, the sand used will become larger grained in order to add strength to the shell.
The finished shell being allowed to dry before going to the pouring floor. Once it arrives on the pouring floor it will be placed in a kiln upside down and heated so that the wax can melt and drain out. This will then be the hollow shell that he molten bronze is poured into.
Finished shells drying.
