[QUOTE="blisters, post: 293326, member: 4992"] I was in a hurry at the time I posted but the reason I was saying it looks like slag is it has gas bubbles so it was hot when formed, it's got that real shiny look to it and it looks like it has contacted gravel (quartz?) when molten looking. It also has a sort of fanned look to the matrix. The suggestions on here are a good start but ultimately it is you who beholdeth the rock. Can you see if any descriptions of basalt/slag etc. fit with what you have? It probably will come down to any fine crystal structure in the matrix so you'll need a magnifier. Jon [/QUOTE]
