Borax is a basic ingredient of most of those fluxes it works fine as a flux but it has a high melting point 1365 f so the metal has lots of time to oxidize while you heat it hot enough to melt the borax this is not a problem on 18k or higher yellow golds as they doesnt oxidize much but on other metals you probably will find that there is
Oct 12 2011 the only reason that i had to wait for the flux gold mix to dry was that i had just sucked the gold out of a bluebowl i would just pour off the excess water of my gold container round takeaway dish and add a tiny pinch of flux to the gold and mix it as the borax helps with the drying of the gold and also coats the gold making it easier to melt

In gold refinement dehybor anhydrous borax is used in flux formulations to dissolve metal oxides and as a flux in gold assaying the addition of dehybor to the smelt is generally 1050 of total smelt weight depending on the process the borax contribution to flux composition can be up to 60 of total flux weight but is typically around 30
May 30 2018 borax image credits silica silica is quite similar to borax in its gold smelting flux properties it is selectively soluble with gold and silver and similarly allows for the easy separation of
Use flux to remove impurities in goldflux is a substance mixed with gold before the smelting process flux generally consists of a mixture of borax and sodium carbonate you need more flux if the gold condition is impure many different formulas can be used as blends flux one method involves mixing borax and sodium carbonate add 2 pinches
Mar 16 2017 rub borax inside the crucible before adding gold dust use flux flux is a mixture of borax and sodium carbonate it helps for gold melting you can mix it with gold dust before melting or during melting oil the mold hold and should be preheated use ammonium chloride on gold after gold pouring it will give shine last and bonus tip is that
Aug 10 2020 how to melt silver with borax the silvers melting temperature is 961 degrees celsius which is higher than gold melting gold is comparatively easy as compared silver but like other metals melting silver and remolding is not that difficult one can quickly melt this metal at home if a proper procedure is known
I am currently using borax silica flour soda ash and potassium nitrate the sludge contains also copper i need a guideline on flux calculation to use in order to move the copper or any other base metal to the slag i would like to know more about flux calculation for gold smeltin
Jun 24 2013 pescador7 flux is a broad term used for ingredients used to change the characteristics of the melt these can be physical and chemical changes there are also quite a few different things which are used to make up a flux recipe some of these are many times normal ingredients then there are also some that are added to change the chemistry of the melt for each type of ore there is no one
