Abstract

The invention relates to the art of a sand having characteristics making the sand useful in producing molds for casting of metal parts and, more particularly, to a method of improving the quality of a quartz sand having natural characteristics making the sand a "foundry sand.' The invention is a method of improving a naturally occurring quartz foundry sand.
