Flux from a few note I have: Normally before fluxing we need to determine whether the ore we are melting is a neutral ore or if it is oxidizing or reducing in nature, here the chemistry of the ore itself can determine what flux recipe is needed, the ore itself can oxidize or reduce metals in the melt, to determine this normally a melt a test ...
When gold slimes contain much lead ( up to 23%). They were treated in various ways, but the best results were obtained by dissolving in sulphuric acid and melting the residues in clay-lined pots (to prevent reduction of the lead by the graphite) with a flux composed as follows: With this flux, bullion was obtained 876 fine.
Chapman flux is just a house flux blend, a general or basic flux mix with most of the general ingredients needed as a general flux (basic minimum ingredients), which may work on a few materials but generally will need adjustment of added flux ingredients of oxidizer, reducer, or acid or basic flux in to build a recipe that will work …
Different techniques are used to melt the gold to a liquid. A common substance used is borax. Borax allows you to melt your own gold in a safe, well ventilated area of your home.
