WARNING! when melting lead there is a potential for it to explode,scattering molten metal all over the place. This happens because sometimes small bubbles form in the lead as it hardens especially if there is moisture present in the mold. Now consider what happens when you try to remelt this piece of lead. As the temperature rises, the gas pressure inside the bubble builds until the melting point of the lead is reached,at which time,POOF!
It happened to me when I was a dumb kid and I still have little scars on the back of my hand as safety reminders. Had it gone in my eye I'd have surely been blinded. Now that I'm a dumb old phart, I use goggles, leather gloves and long sleeves.
One other thing, lead that has been deeply submerged in water,as in old fishing weights, is much more prone to this obnoxious behavior.
