Hey guys, I went on a rock finding mission the other day, and found two types of rocks. I want to know if I can use them. I did the vinegar test and it didn't bubble. Here are the pics..
Sorry but that's doubtful. All of the "black" stones are the same, and all of the "tan" stones are the same. So if one black stone is slate, the others are the same. Thanks though, I really appreciate it.
Yeah shale from what I've read is a form of slate just "grown" or composed slightly different giving it some similar colors just a slightly less durable feel.
