I have been reading Hoke's book and it doesnt seem as elementary as some have claimed. WHen it gets to the part about refining the gold, she says to make sure the scrap you are working with does not contain any content of certain types of metal such as solder, amalgam, mercury and green gold. For a novice like me, it will be hard for me to determine if certain pieces of scrap jewelry contain any of these.
Do not get discouraged if you are a beginner. Read the book, and try to assemble some of the chemicals and materials in question so you can become familiar with them. While it may seem like a maze now, as it starts coming together you'll find it isn't all that complicated. Hoke does a wonderful job of holding your hand----just read and follow her advice, ignoring comments like tossing gasoline on materials you incinerate.
I suggest the above for many reasons. Compare it to playing the piano. When you start, you can't play the simplest of tunes, and nothing makes sense. However, as you study and become familiar with terminology, you gain an understanding of how music is created. With practice, you eventually can play tunes. It's no different with gold refining. Do not expect to read a book and become immediately knowledgeable. Each time you review the book, more of it will make sense, and you'll come to understand common areas. As you apply the tests you read about, more and more will make sense, so you can predict what should happen.
Remember------if you have trouble with Hoke, you're just as likely to have trouble with a kit----and they have you by the short hairs in that you are held captive by them by using their mystery reagents. Learn the basics of refining, which you can do with Hoke, and become self reliant instead of allowing those folks to own your soul.
I did so, with no chemical background. If I can do it, anyone can!
