Gold Purification Using Fire. The use of fire or subjecting gold in a heating process is another common method of refining gold. This process will require a clay crucible, filter, and burning furnace that can produce a heat of up to 2,000 degrees Fahrenheit. Gold, then, must be placed in borax that is able to withstand the heat level.
