Its been a very long time since I have been on here or even thinking about casting but now I want to go at it again but have an issue. I know I had between 300 to 400 lbs of contaminated lead that I bought from a guy on ebay (never trust people on ebay that say they know about not melting zinc weights into the mix)
My kids wanted to move the lead that I have in their garage to the other side without having me there to help or oversee... I have health issues and they were looking out for me. Well they mixed the contaminated lead in with my 1200lbs of known good lead (WW lead alloy that I melted myself). I wanted to separate it so I got some muraitic acid and started putting a couple drops on the lead after scraping it to get rid of the oxide and everything bubbled.
I then put drops on my pewter and boy does that bubble!!!! so my question is..... does muraitic acid react to Tin? my pewter should not be contaminated but it was eating it away.
Any help is appreciated
