Pour off the slag into a heat resistant container The liquid will be too thick to pour once it is cold Add in some borax to thin out the liquid When the liquid cools chip off the glass which will have floated to the top during the cooling process and there is your gold smelted to perfection

The Borax Method is a technique of artisanal gold mining with its basis in the principle that borax reduces the melting point of all minerals including precious metals like gold The melting point of gold is 1063 ˚C which is a higher temperature than can be obtained by cheap torches and burners

Feb 19 2020 · You can buy a microwave gold smelting kit or kiln You place the kiln on a kiln shelf in the microwave The crucible holds the gold while it is being heated and is placed in the kiln with a lid on top Don’t use the microwave for cooking food again if you have used it to melt gold though

The gold slime is then transferred from the acid vat to a filter box in which it is dewatered The dewatered gold slime is calcined and subsequently fluxed as follows gold slime by weight 58 per cent borax 20 per cent sand 12 per cent The manganese dioxide is 10 per cent

The flux is a mixture of several reagent chemical such as borax silica sodium nitrate sodium carbonate and fluorspar Borax is a white crystalline mineral used in glass and ceramic enamel mixes In the smelting process borax helps to reduce the gold smelting point of the charge and capture metallic oxides The addition of this reagent must

Borax and lime are used as flux agents in the cupellation process to separate silver and gold from base metals and other impurities The process is carried out at temperatures between 800 and 900°C ie lower than the melting point of the noble metals and even below the temperature at which the slag becomes totally molten

Borax has a wide variety of uses a component of many products It can be used to glaze ceramic crucibles as a flux in casting and soldering Borax when used in melting of Gold and Silver helps to dissolve Oxides and other impurities and produce a fluid borate slag that collects on
