I can not Thank You enough for putting this information on a sticky. I was the saftey guy in the Navy and I still took the manufacturers word for how safe this stuff is. DOH!, as Hommer Simpson would say. I had not bought any yet, but I was going to 'till today. This the excuse I need to go ahead and get a good rock tumbler and the abrasive kits for it. It will take a few days rather than a few hours I assume but will be worth it in the long run. Besides that, now I could tumble the pretty stones I find.
I wonder if portland cement has enough lime in it to serve as a quench for this HF Acid. I have a half a bag of that left from some project or other. I was thinking of using that to neutralize the muriatic acid left from some brick projects. I seem to remember that cement is made from baked limestone, but the mind does funny things as one grows older. Phill.
