Casting grain is made from gold already alloyed into 14K, 10K, etc., and poured while molten through a sort of ceramic sieve into water. The gold instantly solidifies into little pieces about the size and shape of rice or smaller. This is usually sold in ounce bags or bigger for jewelers to melt and cast into jewelry.
