[QUOTE="AtomRat, post: 234504, member: 3111"] When I smelt alloy ill use both borax and sodium carbonate ( soda ash ). What I read was the borax is to loosen the slag / impurities and help float it all, the soda ash was for degassing the melt. Without degassing, the pour would be very porous. Small bubbles..but very porous. Both borax and sodium carbonate didn't function fully ( no where near as well / clean ) unless we fully submerged the powders using a pluger to sink them to the bottom of the melt and hold it there until the bubbling stopped, which we then stir it all through a d scrape the slag. I don't know if this is of any use for gold smelting but just for some extra info I thought I'd include it in case someone picks up on something relevant :) [/QUOTE]
