Alexander Von Humboldt - Gutachten und Briefwechsel Zur Glasherstellung 1792-1797

Alexander von Humboldt took a major interest in glass manufacturing, including cobalt oxide glazed blue glass (smalt), glass buttons, and glass beads. He was especially curious about the discovery, extraction, and processing of special raw materials and the preparation of wood for the smelter. Understanding the glass manufacturing process was important to him. This book presents his work using transcribed archival documents.
