Borax works by reducing the melting point of gold from its regular 1063 Celsius. By adding some borax to your cleaned gold flakes, you'll be able to melt your gold out of the heavy mineral concentrate to salvage it. Next you'll have to heat the clay bowl (don't worry if it splits or cracks) and add borax.
