Watson Smith’s The Chemistry of Hat Manufacturing gathers lectures delivered before the Hat Manufacturers’ Association, explaining the scientific principles behind the felting and finishing of hats. The book treats the chemistry of fur, wool, dyes, and the processes that turned raw materials into the felt hats of the Victorian era.
A technical work aimed at manufacturers and students of the trade, it documents an industry at the meeting point of craft and emerging industrial science. Smith’s lectures preserve detailed knowledge of materials and methods now largely forgotten.
