The material is then melted in one of our gas and induction furnaces. Depending on the type of material, a unique flux will be added to extract impurities. The flux will create a slag that is removed from the bar after it is poured into a mold. Once the material has the proper flux added and has been melted into a completely molten state, it is mixed to insure it is homogenous. A sample is then taken with a vacuum pin tube that will be later used for analysis. Finally, a dore bar is poured and cooled. Once cooled, the slag is then knocked off, and the bar and sample are reweighed for recording.
