Investing the waxes

Here are the waxes for 2 boxes, sprued and part invested. Investing is the sacrificial mould made around the wax - it needs to be made of a refractory material that can withstand the temperatures involved in the casting process. As these pieces will be cast in pewter, plain Plaster of Paris is sufficent, For bronze, however, I would use ceramic shell, a much more exotic material but one that can withstand the thermal shock of molten iron at around 1500c.
Once the waxes have been fully invested, they will have the wax melted out prior to being baked for 8 hours to burn out the residue and dry the moulds. They will then be ready for casting tomorow.
