Fire in the Crucible offers a compelling exploration of the roots of creativity and genius. Drawing on the lives and work of extraordinary scientists, artists, writers, composers, and inventors, Briggs shows how creative individuals exploit doubt and uncertainty, and the Legend Inc. Sparks, Nevada USA Textbook of Fire Assaying- Bugbee  - by Edward E. Bugbee, , This is a reprint of the 3rd edition, pages (Paperback) The book is accepted as the premier reference text on fire assaying. There is a complete discussion on the fire assay process, including PGM (platinum group metals) assays, complex ores, mill and smelter products, A method was designed for the determination of gold in geological samples such as rocks, ores, and soils buy flame atomic absorption spectrometry (FAAS) and graphite furnace atomic absorption The relative merits of fire assay (Pb and NiS) and wet-chemical attack as methods of decomposition of rocks, soils and sediments are discussed. Amongst various ana- lytical techniques, neutron activation is compared to atomic absorption spectrometry (AAS), and to three types of analysis employing the inductively coupled plasma as a source
