  • Thank You very much for the kind words. Believe me I have had my share of problems. Everything from wrong chemical shipped to me to wrong grade chemical shipped to me.  Most Ebay chemical sellers  will say they sell 100% put when you get around to testing it comes up either the 10% mechanics grade or a 15% fertilizer grade. The best thing I can say to those wanting to attempt this is study, study, study and no soap.

  • Boiling Aqua Regia and oxalic acid. Yellow stuff sticking to the sides of the beaker.
