first off i am some what color blind so work with me. i have been casting for 3 years, mostly handgun and some 30 cal rifle and shotgun slugs. i have always use wheel weights, but i was lucky today and a relative had a free large lead block. it was 10in by 8in by 4in thick and weighed about 80 lbs. i have a cast iron pot and a weed torch to melt down scrap lead into muffins. i had to cut the block in half with a chainsaw to fit it in the pot. the block was probably 50 plus years old. so i am guessing it was for plumbing. but the weird thing was one side had a type of slag on it like cinders from coal that was 1/4in thick. also the lead was pretty close to pure lead. the odd thing is when i melted the lead down it had a lot of blue and bluish gray and some purple colors floating in it. i know i had a lot of the slag in it that i got out but never seen the colors in lead, but i use ww all the time. i dont think high temp had anything to do with it because i had a hard time get the large block up to temp. but is this normal for pure lead or is something else in the lead.
