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.

Molding is a multistep process that will form a cast around the pattern using molding sand. In casting, a mold is contained in a frame called a flask. Green sand, or molding sand, is packed into the flask around the pattern. This is known as metal sand casting. Once the sand is packed tight, the pattern can be removed and the cast will remain.

These metal casting processes may be completed in a foundry or a jewelry studio. Metal casting processes have been known for thousands of years, and have been widely used for creating sculptures, jewelry, transportation, weapons, and tools. The first known cast object is a copper frog that dates back to 3200 BCE, found in presentday Iraq.
