Burn-Out Furnace

This is what is known as a "burn-out' furnace (NOT OVEN!) where the solidified wax melts and leaves an impression in the solidified investment compound. The process is time and temperature controlled. Not all outcomes are PERFECT as they have to be. Sometimes its just a matter of luck to have a good casting for the final process which involves pouring molten metal (platinum, gold, or silver) into the flask and quenching it in water. Incidentally, pure gold melts at 1,945 degrees F. This furnace is NOT suitable for homestyle cuisine, if you know what I mean. Forget about microwaving too. LOL!
