Foundry burn on is the term for a wide ranging number of effects causing surface defects in the sand casting of metals, at high temperatures. Such defects require machining to remove them, adding time, cost and complexity to the process. Coal dust can be added to the sand in up to 5% by weight quantities to prevent the formation of defects.

Even surface finish: Using coal dust low ash in sand casting has proven to produce more even surfaces than Petrobond sand. This is because, with foundry coal dust, sand inclusion and expansion defects are eliminated. It produces whole, solid blocks such with no blow holes even when the crosssection of the cast object is analyzed.
