From the Publisher
This book has been prepared to meet the often-expressed need for a broad and accurate introduction to the fluorescent-mineral hobby. The subject matter is intended to complement, rather than duplicate other recent texts on mineral fluorescence and differs from them chiefly in offering information not only on the minerals themselves but also on the nature of ultraviolet light, the lamps used to produce it, and useful techniques for collecting, learning about, and displaying fluorescent minerals. The agents that cause minerals to fluoresce and those that act to prevent it are explained as well. Some of this information has never before been presented in non-technical fashion and thus may be of interest not only to beginning hobbyists (our intended audience), but also to more advanced collectors.
About the Author
When Thomas Warren founded the Ultra-Violet Products Company, Franklin Delano Roosevelt was being swept into office for the first time. That was 1932, and Tom was busy with research that led to the invention of the handheld ultraviolet lamp - the technological tool which created our fluorescent-mineral hobby. It was Thomas Warren who guided the ultraviolet-lamp industry through its first major crisis - World War II. When war broke out the U.S. government slapped a moratorium on civilian use of steel and copper, two key components of ultraviolet lamps. Not easily discouraged, Tom went to Washington where he was able to negotiate a deal with the government to keep producing lamps for mineral prospecting, especially for scheelite, the main ore of tungsten. This agreement enabled the United States to become self-sufficient in the mining of tungsten, a crucial ingredient used to harden steel. Over the years, Tom has remained committed to sharing his passion for and knowledge of fluorescent minerals. He has helped organize and has participated in hundreds of mineral shows in the United States and in Europe. Through his lectures, he has opened the eyes of thousands to the enjoyment of fluorescent minerals. Today's mineral collectors and fluorescent-mineral hobbyists have acknowledged their debt to Tom, honoring him with numerous awards, including an annual award to be given in his name and honorary memberships in four mineral and gem societies.
