Lost wax casting process


At this phase we use a method called the lost wax casting process.

The prototype of the ring is attached to a wax sprue. This is then attached to a rubber base and the steel flask is placed around the prototype. We mix up an investment (combination of a powdered substance called investment and water) which will be poured into the flask that the jewelry is sitting in. The investment hardens around the ring and after completely drying we place the flask into the oven.


The oven is heated to about 2,000 degrees F. This is to burn out the wax and leave a negative mold of the jewelry item. (Hence where it gets its name lost wax casting process) During the time the flask is heated in the kiln it is brought to the correct casting temperature. We use a centrifugal casting method in which the metal is heated to a liquid state and shot into the mold through centrifugal force. The flask cools and the investment is broken away from the metal leaving our jewelry ready for cleanup and polishing.
