Product Description

             Durable Gold Melting Fire Assay Crucibles

  Ore from the mine, or exploration sampling program is scientifically sampled using a statistically accurate method fitting the desired accuracy, it is then prepared by crushing, splitting and pulverizing. This is a process referred to as sample preparation. Since the original sample may be a hundred pounds or more, a scientific method of obtaining a representative sample for testing of usually 30 grams is used, and it includes reducing the ore to a predetermined particle size and then splitting the ore using a statistically accurate method, to obtain the 30 gram representative sample for fire assaying.
