The mold goes into the cold oven.
The wax is completely burnt away at 800 degrees Celsius. Now you have a cavity in the mold in the shape the wax first was. Therefore we call this the lost-wax-casting method.
The crucible is the melting pot that we use to melt the metals, like gold, silver or a mixture.
We apply heat from a mixture of propane and oxygen gas torch.
The mold has cooled down to the casting temperature of 600 degrees Celsius and goes on the vacuum casting machine.
