Not sure what this is.

Went to a local rails and trails in houtzdale pa. Only went a few feet in and found this not sure what it could be. Its very shiny with yellow spots. I broke it in half and the pieces shard off like glass and the yellow parts almost look green.

Could be what got cleaned out from an old smelting furnace. I found some in PA when I used to trout fish in the Boiling Springs area.

It looks pretty cool whatever it is. You are most likely right thank you for helping!

Also found this on the same trail. First two picture is the whole piece. I broke it into 4 smaller pieces then. The inside is very sparkly and black. It has clear spots that look like some kind of crystal growth or something. I do not know to much about this kind of stuff but it is really neat.

I agree. Find it all over here in NW Pa. mostly in creeks where iron furnaces were. Always just called it "slag".

also could be from a glass insulator used along the rail lines
