I am amassing rather a lot of scrap and there is a limit to the number of balls I want to make. I also have some old jewellery ( hallmarked ) that I want to melt down.

I'm looking at crucibles/scorifiers and tongs/holders.

I will need holders that grip securely as my right hand has a weak grip thanks to an accident years ago.

Is round v square just personal preference or is one easier to use?
