2009/8/20The gold powder, which started out quite dark, is now much lighter in color. It may have been rather loose and flocculent, but now is eager to agglomerate, so it forms lumps and settles quickly. While these instructions sound like a lot of wasted time, when you process what you think is pure gold, you''ll see evidence in the remaining solutions that it was not.
