But if you can find coal slag blasting sand, it's the same thing as TMS.
I don't know if it was coal or iron, but I bought Black Diamond blasting from tractor supply. Even after and hour of rinsing, there was an oil slick on the water and a strong smell. It was awful. I had to scrub my hands and arms several times with dawn to get the residue off.
