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!

Investment Mixing

This machine is used to remove air bubbles from what is known as "investment." The investment is a substance like plaster of paris with silica which forms around the wax mold when it is placed in a cylinder called a "flask." The bubble seals the area on top of the to machine to form a vacuum.

Wax Injection Pot

Rubber molds made in a vulcanizer are used when melted wax are injected into them. This is called a "Wax Pot." Specially formulated wax pellets are melted and the subsequent mixture is pressurized using a generator. The hot wax is depositied into the rubber molds for use in the casting process.

Jewelry Manufacturing

Jewelry manufacturing commonly involves fabrication employing the "Lost Wax" method. The first stage involves carving the item to be made in wax. Modified jewelers benches such as the one depicted are utilized.
