Tiny conical crucibles capable of holding about a couple of ounces of gold are used the gold dust is melted in these with borax and niter as fluxes the slag is lifted off the surface of the gold when the latter is supposed to be clean by means of an iron rod and the gold is then granulated by pouring into water
