Black Beauty is actually the stuff I was using. It's as sharp as silica, but cheaper. I would imagine a really huge job might go a little faster with an industrial compressor and sand pot, but you've got to be hooded, sutied, gloved, and wear breathing protection. Wet sandblasting requires a good pair of closed sided goggles. I also recommend a hat to keep some of the sand out of your hair.
