Good day to all,
I was melting some silver with karat gold to inquart down to 25% /6k. Went well in melting dish, stirred for 60 seconds with graphite rod. I don’t think I had enough cold water in the metal bowl when I poured the molten metal? Also no ice? Maybe didn’t pour in a small stream either?
The metal fused to bottom of bowl in one blob, size of a silver dollar or so. After ten minutes banging bowl upside down and clawing with tools, it separated in one piece.
My concern is contamination from the bowl, there seems to be no evidence of bowl material (steel or plating) in the blob.
Going forward, do I need to re/melt and pour better to get the cornflake material, or can I go to ahead and process the blob from here with dilute nitric as I planned?
I suppose another melt and mix to assure good equal 6k would do no harm anyway?
Any input valued. Than you and happy new year to all
