Glass Of The Alchemists

"The present study illustrates how glass played an important role in ancient technical and alchemical literature, and how the chemical operations devised to improve glass making inspired by alchemists to better define the theoretical boundaries of their discipline and, more specifically, the concept of transmutation."--Book jacket.

Explores the origins and practices of early alchemy • Examines the oldest surviving alchemical texts, the original purpose of the “Royal Art,” and the first alchemists, showing how women dominated early alchemy • Looks at the historical setting for the first alchemists, with detailed accounts of their apparatus, recipes, chemical processes, and the ingredients they used • Reveals how changing the color of materials was more important in early alchemy than transmuting base metals into gold Investigating the origins of alchemy and the legend of the Philosopher’s Stone, Tobias Churton explores the oldest surviving alchemical texts, the original purpose of the “Royal Art,” and the first alchemists themselves. He reveals the theories and philosophies behind the art and how early apparatus and methods were employed by alchemists through the ages. Showing how women dominated early alchemy, Churton looks at the first known alchemist, the Jewess Maria the Prophetess, inventor of the bain marie, still in use worldwide today. He also looks at early alchemist Cleopatra (not the well-known Egyptian queen) and 3rd–4th century Egyptian female artisan Theosebeia, who had a guild of adepts working under her. He examines in depth the work of Zosimos of Panopolis and shows how Zosimos’s historic work inspired the medieval view of alchemy as an initiatory path whose stages follow the transmutation of base metals into gold. Exploring the latest research on early practices in Upper Egypt, the author discusses the political and industrial realities facing the first alchemists. He examines the late antique “Stockholm” and “Leiden” papyri, which offer detailed knowledge of the first known Greco-Egyptian chemical recipes for gold and silver dyes for metal and stone, and purple dyes for wool. He emphasizes how changing color in early alchemy was misinterpreted to imply transmutation of one metal into another. He reveals how the alchemical secrets for working with the “living statues” of the Egyptian temples was jealously guarded by the priesthood and how secrecy helped to reinforce beliefs that alchemical knowledge came from forbidden, celestial sources. He also investigates the mysterious relation between alchemy, spiritual gnosis, Hermeticism, and the Book of Enoch. Revealing the hidden legacy of the early alchemists, Churton shows how their secret workings provided a transmission line for ancient heretical doctrines to survive into the Renaissance and beyond.

In The Business of Alchemy, Pamela Smith explores the relationships among alchemy, the court, and commerce in order to illuminate the cultural history of the Holy Roman Empire in the sixteenth and seventeenth centuries. In showing how an overriding concern with religious salvation was transformed into a concentration on material increase and economic policies, Smith depicts the rise of modern science and early capitalism. In pursuing this narrative, she focuses on that ideal prey of the cultural historian, an intellectual of the second rank whose career and ideas typify those of a generation. Smith follows the career of Johann Joachim Becher (1635-1682) from university to court, his projects from New World colonies to an old-world Pansophic Panopticon, and his ideas from alchemy to economics. Teasing out the many meanings of alchemy for Becher and his contemporaries, she argues that it provided Becher with not only a direct key to power over nature but also a language by which he could convince his princely patrons that their power too must rest on liquid wealth. Agrarian society regarded merchants with suspicion as the nonproductive exploiters of others' labor; however, territorial princes turned to commerce for revenue as the cost of maintaining the state increased. Placing Becher’s career in its social and intellectual context, Smith shows how he attempted to help his patrons assimilate commercial values into noble court culture and to understand the production of surplus capital as natural and legitimate. With emphasis on the practices of natural philosophy and extensive use of archival materials, Smith brings alive the moment of cultural transformation in which science and the modern state emerged.

Gold Nanoparticles for Physics, Chemistry and Biology offers an overview of recent research into gold nanoparticles, covering their discovery, usage and contemporary practical applications. This Second Edition begins with a history of over 2000 years of the use of gold nanoparticles, with a review of the specific properties which make gold unique. Updated chapters include gold nanoparticle preparation methods, their plasmon resonance and thermo-optical properties, their catalytic properties and their future technological applications. New chapters have been included, and reveal the growing impact of plasmonics in research, with an introduction to quantum plasmonics, plasmon assisted catalysis and electro-photon conversion. The growing field of nanoparticles for health is also addressed with a study of gold nanoparticles as radiosensibiliser for radiotherapy, and of gold nanoparticle functionalisation. This new edition also considers the relevance of bimetallic nanoparticles for specific applications. World-class scientists provide the most up-to-date findings for an introduction to gold nanoparticles within the related areas of chemistry, biology, material science, optics and physics. It is perfectly suited to advanced level students and researchers looking to enhance their knowledge in the study of gold nanoparticles.
