Hello all, after feverishly searching online and in the forums/book I can not for the life of me find any information of what a deep blue stannous test concludes. I had about 40 ceramic cups from telecom boards that I added to the ball mill, ground them up as much as possible, which really didn’t work so I just took a hammer to them, and then treated them with some dilute nitric acid. I did a stannous test just to see if anything came up and I got this color. After that I treated the remains with aqua regia and I believe I have platinum in this newer solution with a slightly yellow stannous.
I’m not sure what this first nitric solution could contain?? Has anybody else gotten this reading as well? That is the solution sitting next to the stannous, I appreciate it!
