I did not know this. I don't want my lungs going anywhere without me. My lab overhaul (still in the framed stages, electrical 80% done) has much improved suction and dust containment. I've been a little paranoid about breathing dust and junk. I also hated the mess in my previous lab. It's too bad about the stuff 'cuz it works real well. Thanks for the heads up.A word on what you use to pumice, I'm sure you know. There is a problem with your lungs going south from what you use. Not right now, right now, but, later, later.
Some suppliers don't sell it for this reason.
