This is a JERWYK Auction body {background-color: yellow} Techniques For Dyeing-Treating Gem Materials Gemstone treatment and enhancement remains a mystery for most people, but this multi-media CD-ROM tutorial in Adobe's PDF format covers methods of treating and altering the colors of gemstones so that the average lapidary hobbyist can perform the "arts of dyeing and staining." The tutorial emphasizes practical DIY techniques for lapidaries on color changes through dyeing and then gives how-to consideration to many other forms of treatment and enhancement. The informaton is also usefu for gemologists, too, because a true jewelry specialist or gemologist can more readily detect treatments just by knowing exactly how it's done - and where to probe for evidence of alteration.The specific techniques include: /font> dyeing with aniline dyes dyeing with metallic acid dyes dyeing with chemicals color changing with heat color alteration through smoking the benefits of ordinary bleaching some workshop level techniques for heat treatment (with complete explanations of the more costly - and dangerous - methods such as hi-temp heating, irradiation with cyclotrons, diffusing, lasering, etc.) coloring and impregnation as treatments for color change and "camouflage" of imperfections backing techniques Besides a general and intricate explanation of techniques, there are separate sections devoted exclusively to certain recognized (but little known) DIY enhancement techniques as applied to such specific gem types as: -- Emeralds -- Rubies, Sapphires and Paraparadshaws -- Chalcedony -- Coral -- Opal -- Tiger Eye -- Three Black Onyx methods( ALL black onyx is dyed gem material.) -- Turquoise -- Pearls Please address any questions prior to bidding through Ebay's more private and secure message service.
