Nice! I haven't tried casting yet, kinda afraid of what I'll get started! But from what I've read, any zinc weights in your pot "should" have floated to the top along with the steel clips, and you should have been able to scoop them out. They say that the zinc weights melt at a much hotter temp than the lead, and it's really not that likely they'll melt into your lead unless you just get it really hot. But, I don't know that for fact, just what I've read.
