Download or read book Handbook for the Amateur Lapidary written by James Harry Howard and published by Ravenio Books. This book was released on 1935 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Man was cutting, carving and polishing gems long before he began to leave written records of his doings. Many Museums have countless examples of the lapidary work done by those artisans and artists, who wrought from raw materials, with exceedingly primitive equipment, objects of art that our modern workers would be hard taxed to surpass. Today, in the Far East, native artisans with hand or foot driven wheels are producing perfect polishes on difficult gems, showing workmanship of which we amateurs with full complement of tools may well be envious. Gem cutting is only one of many arts that are old. Ceramics, wood working, metal working and so forth are old arts. The thing that is peculiar is that these other arts all have their extensive literatures. One may go to any public library and find many volumes on any of these subjects except gem cutting. These volumes are all-revealing, authoritative and detailed. But the subject of gem cutting is shrouded in mystery. Few have written even in generalities on the subject. The Author, several years ago, conducted a search for such literature. He found absolutely nothing. Much later he learned of and borrowed, a copy of Oliver Byrnes, “Handbook for the Mechanic, Artisan and Engineer” and found in it an exceedingly interesting chapter on gem cutting. But the volume was written about 75 years ago, probably had a very limited circulation, was never reprinted, and not one library in fifty ever heard of it. That is the only volume the Author has ever found that treats even briefly of gem cutting. This excludes of course such texts as “The Gem Cutters Craft” by Leopold Cleremont which have chapters on the technique of cutting, but that treat of it so generally that they cannot be used as instructions. The art for some reason has always been passed down from generation to generation by apprenticeship only. When the Author began the above mentioned investigation he was told “The cutting of gems can be learned only through an apprenticeship.” There is no desire here to picture the art as an easy one to learn nor to minimize the skill that is shown by the work of the professional lapidaries, nor to intimate that the professional could, if he would, reveal all his secrets in one brief volume. The desire is to lift the cloud of mystery that has always surrounded the operation and show that actually there is nothing mysterious in the practices of the profession, but only certain basic rules, which, if obeyed, will bring definite results. It is hoped that the instructions herein given are sufficiently explicit that the beginner in the work will have no especial difficulties. It is hoped also that they are not so tedious but that they will be readable by those who do not propose to cut gems but who are, nevertheless, interested in the operation.

Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Forensic Geoscience provides fundamental training in geoscience as developed through the lens of its forensic applications. It incorporates a range of topics including geophysical methods of grave detection, the mineralogy of art, identification of microfossils, and comparison of soil trace evidence samples. Each topic is introduced using core concepts that are developed with increasing complexity in order to give readers an understanding of the underlying scientific principles involved and a taste of the wide range of possible forensic uses. A variety of detailed reference tables have been compiled for the text and each chapter contains lists of references to applicable textbooks and journal articles. Examples of real criminal cases are also presented in each chapter to make the connections between theory and real world application. The goal of this book is to give readers a familiarity with the wide range of ways in which geoscience principles and geological materials can be utilized forensically.
