my pattern making work:
I use green sand, in Brazil we not find petrobond.Celsoari , my hats off to you sir :thumbup:. I would have never thought of using noodles.
Very nice finish on the castings, are you using green sand or Petrobond?
meus chapéus para você senhor. Eu nunca teria pensado em usar macarrão
Muito bom acabamento, você está usando areia verde ou Petrobond?
Check out Cody's Lab on youtube. He has a entire series on gold purification.Fascinating stuff! Reminds me of my late wife who did casting but with gold.
She extracted gold filled but rotten teeth and melted the gold into little ingots. Made patterns out of wax , did the lost wax process and then centrifugally cast it. Only one fault, it would not assay as the impurities were platinum.
Which all reminds me that there is a large quantity of used amalgam which is silver and mercury under my desk Is there any way to get the silver out, please?
