how to recover the fine gold. (from black sands)
Keeping the flame on the gold, add a pinch of borax to the gold, and turn up the heat slightly and carefully. As the gold gets hotter, it changes color to a bright greenish-orange as it nears it's melting point. All the fine particles of gold will melt together into a bright ball. Remove the flame and let it cool down slowly on it's own.

Take the dust and put it in a series of casserole dishes. The dust must not be more than 1" high and it must not be packed into place. This is very important. If sufficient air does not reach the sweeps, they will not burn completely. If there are buffs and large amounts of paper, these must be put aside for a separate burning.
