But you can burn the heck out of it.
I had a half full pot in the RCBS Pro Melt all melted and it was time to empty my jar of reject bullets and shot into molten mix. Some how a loaded 9mm fmj was in the jar and now sitting on the top of the hot pot. I grabbed the ladle to scoop it out when it exploded, I was luck I was wearing glasses and long sleeves. I had lead stuck to my cuff and to my palm, all over my fingernails and in my hair. The underside of the bill of my ball cap was splattered. A slight burn on the forehead and a bruised pride. The inside of the pot now has a hole where the brass casing is lodged. I haven't found the ladle yet, must have thrown it somewhere in the barn.
