Hmmm I have head that lava rock is questionable. I wanted to try some red sand stone I have in my front yard but left it soaking for about 2 weeks and it started leaving a lot of deposits so dropped that idea but I found some rocks in the foot hills of the Sandia mountains that looks sort of like slate that I'm thinking of trying out. It's kind of disappointing though because we do have a lot of cool looking rocks.
