Guidelines on flux calculation gold smelting
A gold-iron phase diagram derived from the data of Seigle (1956) is shown in figure 5, and illustrates a number of features important to removing iron from gold. Firstly, no more than 27% Fe can be tolerated when the gold melts to avoid inclusion of refractory high-iron solid phase components in the bar.

What Does Borax Do When Melting Silver?
Borax is frequently used to season crucibles. It forms a nice base layer for the metal to melt in and it kind of "floats" on the molten borax. This prevents the silver from picking up contaminants in the form of dust. Metal contamination is a big deal. It leads to more work, structural failures, and even safety hazards.

What is Flux and how does it Work?
In metal refining, flux is used to help remove impurities and change the fluidity of the melt. Once activated by the furnace's high temperatures, the flux breaks down and lowers the melting points of all the other materials in the crucible. As the refining process continues, the flux causes the other materials to oxidize and breakdown even ...
