I was touring Alberta's badlands over the past few days, and in one of the rock and fossil shops I stopped into I came across this material. It is crystalline silicon carbide (plain old grit). Did a bit of research, and it turns out they make silicon carbide by combining coke with sand in an electric oven at temps above 2200 degrees Celsius. (Coke is coal cooked in a furnace without oxygen so that it doesn't burn but the gases are driven out of the coal). Details aside, this is what you get. I think it looks really great. Very crumbly though, if I keep handling it, soon it will be all broken down and ready to throw into my tumbler! ;D
