...glasses! I often thank the Lord for blessing me with bad eyesight. Been wearing glasses since before 1st grade. I've lost count of the times they've kept me injury free growing up in the family machine shop, shooting, working in chem plants and refineries, riding a motorbike and tonight casting.
It was a rogue lead droplet that lept out of the pot as I let some excess sprue material run off the end of the mould. I saw it jump like a flea and faster than the second syllabel of "Gotcha" there was a lead splatter about 30 caliber on the center of my right lense. I calmly set the mould down, placed the ladel in the pot, stepped back and pealed the lead daisy off my lense. It melted the surface under it. The replacement safety lense will cost me a few dollars, but less than the emergency room, won't be any lasting scarred eyes and not a bit of pain.
Folks, if you spend enough time in front of a lead pot, you will get some on you. Be ready for it.
