That would be an amazing thing to watch. Thank you for explaining it all. I think I have a cutting torch from a garage sale somewhere. If need to get it checked out first. Always more to learn!
i asked one of the refineries out of state the cost of getting silver refined and what technique they used… it would have cost 20% plus shipping… they told me tht they used fire refining and not electrolytic refining.
I would have paid for electrolytic refining since that does result in 99.99% purity. Fire refining is what i basically described… they would melt the silver in a pure 02 environment… I think that can be achieved easily by 02 injection… I actually stumbled on it years ago when I experimented with scrap silver melting… I thought that 02 injection would clean up the silver faster and I was surprised to get spitting silver… looked it up and found that spitting silver was pure…used oxyacetylene because I had it for steel and the flame was big and very hot…
good luck… try an ounce first and then more,… if you have a ton of scrap, you could melt a lot more and keep the rest as ingots… alloying with copper later if you need sterling… just remember that it’s by weight percent…you need an accurate balance scale for that…
Interesting, sorry to hear of your continued frustrations. My old setup was a 1lb propane canister with a smith fixed regulator and little torch with paige tips and a 5lpm O2 concentrator and it had no problems other than the torch in general was a bit finicky for me. Nothing like you’re experiencing. I could use a rosebud and melt for casting with a 4-5" flame on my setup.
replaced it with a meco midget when I moved overseas and that’s more to my liking.
I don’t see an obvious source of your problems although I will say there is a noted problem with little torch clones, the chinese knockoffs that look the same but might use different materials, valves and poor fabrication. A faulty regulator might also give you those problems although it would be a great surprise from Smith.
Best of luck - Lawrence
