"The volatile matter content of coal varies widely for the four main coal ranks and is low for high rank coals such as anthracite and higher for increasingly low rank coals. The higher the volatile matter content the more reactive a coal is which means it can be more readily converted to gas while producing less char.

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.
