I can tell by the pieces this stuf was in layers. Some has a white creamy color molted in that stuff is high quality too. I found some that was battleship grey that's really slick too. There was a lot of this banded stuff but it's not as good of quality and a lot harder to work. The top one is dacite, but bottom two are from windmill rd. I was trying to remove crystal from base got my flake but broke my point
