Re: how to dye rocks
The information you require is in a paperback book called "The art of Gem Cutting" by Dr H C Dake published in 1963 by Gembooks of Mentone California. It doesn't appear to have an ISBN and I doubt its still in print. Your local library may be able to get a copy in or you local lapidary club may have it in their library.
