Book excerpt: Following a hit and run that injures his son, John Spector is shocked when the driver comes forward to confess the accident was planned and that John made the arrangements. Upset by the suggestion, he embarks on a quest that will take him through the bizarre underbelly of the city in search of the truth. Even when faced with demons bent on stopping him, haunted by dreams of a man he's never met or sidelined by concerns for his mental health, John remains unshakable. Only after his path leads to the philanthropist Charles Dapper does his determination waver, for this is when he must make an extraordinary self sacrifice to realize his goal or risk losing everything.

Download or read book Silver by Fire Silver by Mercury A Chemical History of Silver Refining in New Spain and Mexico 16th to 19th Centuries written by Saul Guerrero and published by BRILL. This book was released on 2017-09-11 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Silver by Fire, Silver by Mercury: A Chemical History of Silver Refining in New Spain and Mexico, 16th to 19th Centuries, Saul Guerrero combines historical research with geology and chemistry to refute the current prevailing narrative of a primitive effort dominated by mercury and its copious emissions to the air. Based on quantitative historical data, visual records and geochemical fundamentals, Guerrero analyses the chemical and economic reasons why two refining processes had to share production, creating along the way major innovations in the chemical recipes, milling equipment, mercury recycling practice, and industrial architecture and operations. Their main environmental impact was lead fume and the depletion of woodlands from smelting, and the transformation of mercury into calomel during the patio process.
