Originally published in 1911. PREFACE: The author has long recognized the need of a work on fire assaying that treats the subject from the scientific and rational point of view rather than from that of the rule of thumb The book is closely confined to the subject of fire assaying, which it treats in detail. The chapters on Reduction and Oxidation Reactions,
Crucible Assay and Assay Slags, and Cupellation, outline scientifically the principles of assaying…….. Many of the earliest books, particularly those dating back to 1900’s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
