Somebody was throwing away a tile cutting saw, still in the box. It had been used, but probably only once. There were cut tile pieces next to it, so I'm thinking that maybe a guy had some tile work he wanted to do, bought a cheap Harbor Freight saw. Used it for the work, then threw it away. I took it home, and Saturday afternoon, tried cutting some rocks with it; as a with-kids project. I already had the rocks; I was saving them because I really like the way metamorphic rocks look. I study their appearance because I want to be able to reproduce that layered look quickly and easily with paint.
As it turns out, The cut edges show the layers in a very nice way. Here are a couple pictures of the results. Most of these rocks have a spray clear coat on them, to make the patterns show more.
