My solution was from computer prongs, plates, and pins. I did have some of the pieces stick to the magnet. I had used another process (Shor) before I learned of the forum and read Hoke's book. My original AR solution was emerald green. I added the calculated amount of SMB and the solution turned a dark brown. I tested with stannous, which was dark positive and I added more SMB. I could not get a negative reading of the solution, because it stayed dark brown. I have 5 quarts of this solution. I canted the solution, rinsed with ammonium hydroxide, water, and DW. I dried the powder and it was this reddish color. I picked out some blue particles. I then tried a to melt the powder and it smoked green and blue. After melting, the pieces looked like copper. Through out my processing I aquired three separte powders: red, black, and brown. None of the three melted only smoked and turned to black ash. At this point I took some more of the original brown solution, rinsed with ammonium hydroxide, and some water. Stannous test was still positive. This batch solution turned back to a light emerald green. After my reading Hoke, I tried to cement the solution that I thought contained gold with solid copper wire. I knocked of the particles and when nothing else changed, I poured off and rinsed. This is the redish solution I showed in the picture and filter. After settling all night, the water was clear. I used a box cutter to cut the plastic off of the copper wire and I did not clean the wire first. My original solution was processed in my barn. My tools on the wall rusted. I kept the solution covered while it was processing. I don't know if any rust oxides could of dropped into the batch or it came from my original gold pins. To the best of my knowledge and notes; this is all I have for that process.
