I have not been knapping glass for a while. Now I'm practicing with punches, and picked up some fat glass shards again, since good rock is too rare around here to ruin it and glass is nicely easy on beginners. But ah, yes, I must have forgotten:
That stuff is DISGUSTING! horrible tiny fragile shards of really all sizes everywhere.
I'll have to get me some old sink or some floor tiles or whatever. Knapped glass stuff looks real nice, but the mess it leaves in the process is horrible. I fell I want to wear full body protection and a filter mask and goggles and whatnot.
