Thanks Skip! I looked up pictures of slag glass and pictures of green obsidian and I have to say that there were more pictures of green obsidian that looked like my rock. I have pieces that I broke off and none of them are opaque. One piece has one small spot at the very edge (>1/16th") that is a little translucent and that's only where a gold colored streak is.

Is there any way it could be flint?

Finally got pictures up.

My daughter found this rock on our property in SW Kansas. I'm sure it wasn't formed here but brought in from the previous owner of our house. I've done some research on it (which brought me to this site) and I'm pretty sure it's green obsidian. I've Looked up pictures of both green obsidian and pitchstone and it looks more like green obsidian. One site had a description and it was right on with Green obsidian. I would like to get your opinion. Also, I can't find the right forum to put this in, but when I go to my profile and try to edit it just comes up with a screen full of odd font symbols.
