The American Petroleum Institute (API) has established specifications for the use of barite in drilling mud. To meet these specifications, the barite is finely ground so that at least 97% of the material, by weight, can pass through a 200-mesh (75-μm) screen, and no more than 30%, by weight, can be less than 6 μm diameter.

Borax is a mineral that is often used as a flux in metalworking. It helps to remove impurities and oxides from the metal, allowing it to flow more easily and preventing it from oxidizing during the melting process. Borax is commonly used in silver melting because it has a low melting point and can help the metal to flow smoothly.
