The Principles of Leather Manufacture

"The Principles of Leather Manufacture" by H. R. Procter is a book that looks at how leather is made, from old-fashioned ways to modern science. It connects hands-on tanning with the science of chemistry, for both scientists and leather workers. The book starts with the very first leather making, when people used animal skins for clothes. The author explains how old methods, like using animal fats on skins, became better over time. These methods grew into the processes we use today with plant materials and salts. The author also mentions big improvements in the industry and points to ancient writings, promising to show the chemistry that changes animal hides into strong leather.
