I notice it happens more when I melt more previously melted cast iron. Fresh iron does not do it as much. I do not worry with it. I just thro...
Another thought on the sand looking stuff.... How old is the scrap you are using? In other words, could the scrap be covered in lead based paint which is leaving the residue?
