Chipped these out today from that chunk of 17th century iron smelting slag I found. I was
hoping to get a big blade but the first good hit broke it into three pieces

Had some freeze fractures, bubbles, and junk in it.
You can see in the big triangular point a hole that goes almost all the way through, ifin I could have gotten another flake or two it would have
been clean through but I wussied out

The little stemmed was a corner notch until I popped the ear off

Its works like obsidian but I've never seen
purple obsidian
