I just got a stone in the mail that I bought off ebay. I rolled the dice and I think I crapped out. It came stuck in a block of wood, so I cut it out. I think the previous owner used oil on it or laquered it into the wood because it is caked with black crap :-/ (anybodys guess) top, bottom, and sides. I tried dial and a wet/dry sanding sponge it with minimal results. Any suggestions on how to clean it up? I'm thinking about using paint thinner on it. Will paint thinner hurt it in any way if it is not a natural stone? Any suggestions on how to proceed would be greatly appreciated.
Anyone have a guess on what it is? Its 7 3/4" X 2 1/8" X 6/8" It gives off a tan slurry, like the dots in the first pic, but it is a B***H to get slurry raised!!! Tons of preasure and like 150 strokes with a small survival knife sharpening stone produced minimal slurry.
