slag glass point

[Josh B]

First flake I grabbed out of my bucket was some slag glass straightarrow gave me.  It works exactly like obsidian.  I tried notching with a sharpened tine instead of my copper notcher and kind of screwed it up.  I need to get me an ulna bone.  It ain't perfect, but it should do it's job if I do my part.  Thanks for looking.  Josh

Lookin good doc.
You can get some of the wildest colors in that
 slag glass. I usually wind up with bubbles.
Powder blue some times.

This is the first time I have seen that type of glass. Very nice point

Thanks fellas!  I only got a couple pounds of this stuff and most of it was pretty fractured up.  When you hold it up to the light it's sort of a translucent  grayish tan color with black specks.  I had heard of slag glass of course, but until straightarrow handed me some  I'd never seen it.  I'd like to get my hands on some of the colored stuff some day.  As you can imagine there's not much of an iron industry in Kansas where I'm from.  So it's a bit hard to come by.  Next time I deliver to a steel mill, I'll ask around about it.  Josh
