A group of miners in the Philippines has demonstrated that borax when used as a flux for smelting gold out of heavy mineral concentrates is an effective and safer substitute for mercury. Objectives.
This is because using borax as the flux reduces the melting point of all the elements in a piece of ore including gold. While out in the field a gold prospector can grind and wash a piece of ore then mix it with borax in a plastic bag. The bag is then placed in a bowl or crucible and heated. The heating action is what triggers the borax to

sodium hydroxide bad idea keep it out good old borax You want your basic starting flux to be borax soda ash (50/50) not just borax then to that you add other components (flux ingredients) depending on the chemistry needed (oxidation/reduction) to take place in the crucible during the smelt for the material you are smelting
So if your prill is 10 gr too light you should add another gram of to the next assay. It ll be close enough. Another thing that can go wrong is that sometimes the ore produces a melt that is too thick and viscous to pour properly. Could probably add more sand or more effective would be to add a couple of grams of Borax.

Borax is also used mixed with water as a flux when soldering jewelry metals such as gold or silver. Also used to glaze crucibles and casting process. You will need to glaze your crucible with borax before you melt any metal in it. This ensures that your metal doesn t stick to the ceramic crucible. Borax (Sodium Tetraborate Penthydrate)
