Neat finds! Maybe some kind of slag glass?

i agree, they look like slag glass. It may be leftovers from a metal smelting process or possibly an industrial coal fired boiler. Either way there is a good chance it has heavy metals like arsenic, lead, chrome, nickel and mercury in it. Between pieces of sand and air bubbles in the glass i think you will not be able to get a decent shine out of it.

I have found a lot of it in the creek near my house and along the shore of the lake, that came from Cleveland glass company that made window glass a couple towns over. most of it is black or has that green tint since they didn't do colored glass. I also found some on the backside of a hill at work that must have been from the old coal furnaces because our slag now days is grey and loaded with bigger gas bubbles.
