Hi
I don't post at all but have to sound a word of caution working with molten lead. When I was in Grade 6 I made my own lead sinkers. One day I was using an old soup ladle to pour the lead in the mould, when the ladle broke (while full of lead). It fell in the pot of molten lead which splashed up with most finding its way into my one eye. It F***ing hurt. I stuck my head under a tap. When my Mom opened up my eyelid, after trimming away the fused eyebrows, all she could see was a lead eyeball. It had totally molded around my eyeball!!! It cost emergency trips to the GP and optomotrist!! My eyeball was actually blistered!! Luckily it was fine after a week with no long-term damage.
So be carefull, wear some eye protection and do it in a well-ventilated area.
Regards
Jacques
