I was melting some more wire shielding tonight but the smoke was worrying the wife, ( she is usually not around when I do this sort of thing.
So I moved outside on the dog porch...
When everything was nice and hot I had a lead explosion. Molten lead flying for 5 feet in all directions. I have NEVER had that happen before.
Either something like a live round got into the chunks of lead tubing. OR... a piece of ice was blown off the over-hanging tree and landed in the pot.
Either way, it is a very good thing I had a face visor, heavy gloves and my old Carhartt jacket.
