"In 2009, Perú was the world's leading producer of silver, the world's second leading producer of copper, and the leading producer of gold in Latin America. However, Perú's role as a producer of metals extends for centuries into the past. Mining and Metallurgy in Ancient Perú documents the use of minerals, metals, and mineral resources in ancient Perú for pigments, industrial stone, and the aesthetic and artistic use of gold, silver, copper, and platinum. The tools and methods used for mining, as well as ancient mining sites in the extensive Andean region, are described here, as are metallurgical techniques and fabrication procedures. The volume also provides forward-thinking analytical data on metals, artifacts, and alloys. A detailed pyrite mirror, featured on the cover of the book, symbolizes the spectacular workmanship and blending of utilitarian craft and mineral resources in ancient Perú."--Publisher's description.
The Encyclopaedia fills a gap in both the history of science and in cultural stud ies. Reference works on other cultures tend either to omit science completely or pay little attention to it, and those on the history of science almost always start with the Greeks, with perhaps a mention of the Islamic world as a trans lator of Greek scientific works. The purpose of the Encyclopaedia is to bring together knowledge of many disparate fields in one place and to legitimize the study of other cultures' science. Our aim is not to claim the superiority of other cultures, but to engage in a mutual exchange of ideas. The Western aca demic divisions of science, technology, and medicine have been united in the Encyclopaedia because in ancient cultures these disciplines were connected. This work contributes to redressing the balance in the number of reference works devoted to the study of Western science, and encourages awareness of cultural diversity. The Encyclopaedia is the first compilation of this sort, and it is testimony both to the earlier Eurocentric view of academia as well as to the widened vision of today. There is nothing that crosses disciplinary and geographic boundaries, dealing with both scientific and philosophical issues, to the extent that this work does. xi PERSONAL NOTE FROM THE EDITOR Many years ago I taught African history at a secondary school in Central Africa.
Gives you a thorough, yet easy-to-understand introduction to the principles of composition control, gas evolution in melts and inclusion-forming reactions, as well as the basic concepts of crystal growth and solidification that aids you with interpretation of structures. This volume discusses casting, molding and coremaking practices in a series of articles that describe the basic steps and equipment associated with each process, along with their advantages, limitations, and applications. Each article is preceded by a review of the manufacture, design and selection of patterns. Book jacket.
