Several years ago, the middle school where I used to work at got hit by lightening, and a good part of the building burned down. A few years after that, kids were bringing me glass, but they couldn't fiqure out why it looked that way, or what in fact, it actually was. The only thing I could think of, was that it was glass from the windows which had melted and the ashes as they landed on the liquid glass as it was cooling down. Here are a couple of artifacts from that fire. I tried cabbing one of them, and it sort of worked. Notice how you can clearly see the ashes inside the glass as well as other kinds of colors.

Gil-
That's a cool idea. Too bad about the school though. Did you try to polish them?

If your schools are built like ours with the glass block and all the windows then there would be alot of that moderen day obcidian laying around.

That is sad about the school, but the glass is neat. Any idea what would have cause the colors?

Did the kids find the glass outside? When lightning hits sandy soil it can fuse the sand into natural glass called fulgurite. It's just a thought.

Cher, I'm thinking it could have been the combination of whatever might have fallen onto the glass as it was cooling. From the reddish/brownish color, perhaps some form of iron.
Joe, you make an excellent point. The area where the kids found the glass happens to be very sandy in a desert type way. I do have a fulgurite, and have seen many more. Most of them, as well as mine are not clear, but rather a greyish/blackish color. The fire marshall determined that the lightning hit the library and the fire spread from there, so I still presume it's melted glass.
