The problem with that is that slate when smashed is really sharp, so you will have to take the edges off a bit if you are handling otherwise it will cut your hands to shreds. I'm probably stating the obvious here but I thought I had better post it.
You could indeed smash up the slate but be sure to wear eye protection and try and smash it under an old towel or curtain on a hard surface that you dont mind screwing up. I know from experience aquascaping my friends mbuna tank for him, we decided to use slate pieces and smash them up to create a stacked mound effect. Bloody razor sharp slate flying hundreds of feet in all directions!
