Casting

The alloyed gold is melted in a crucible to a specified temperature, based on its color and fineness. When everything is ready to go, the flask is removed form the oven and placed into a vacuum. This process will draw out air that might cause turbulence or displace the soon to be added gold. The gold is carefully poured into the flask, while the vacuum continues to pull. The cast flask is set aside and allowed to cool until the gold has set (the glow is gone from the visible metal). This completes the 'Lost-Wax Casting' process.
