Yeah, there are several grades of arsenic, the industrial stuff I used was supposedly the highest industrial grade, but I couldn't get any acceptable result from it. There are industrial uses for arsenic, it used to be used to treat timber as a rot and insect preventative --- as well as other uses that I do not know.
