hi members I need your help. I have a VERY GREEN AR and Ive tested with stannous chloride and got a Dark Purple almost Black stain verifing gold in the solution along with a very BRIGHT orange color.
the materials i used were gold foils in coffee filters that i had filtered out and rinsed real well out of my AR solutions they came from cell phone boards as well as virgin gold plated circuit boards that have never seen solder.
I put all the foils into a 2 liter container and put 200ml or so of HCL and then added 15ml or so of Clorox bleach. i covered and let sit in the sun for days and when i came back to check i poured out green liquid and filtered the rest out through a filter which was basically mush from the filters that held the gold foils i have added distilled water and a tad bit of Urea to make sure all Nitric was out. And my AR is still the same green color.
i dont know what went wrong. can someone please help me!?!
