AND

If the truth be known. You don't actually need a flux to smelt gold. It will stick to itself fairly easily without flux, even with quartz type impurities. It just needs a tad more heat and pressure to muster the little golden balls into one blob if you are using an oxy/open crucible, or a bit more time if you have a furnace.
