The Handbook of Soap Manufacture

A clear‑cut guide to the world of soap making, this handbook blends a concise history of the craft with the latest practices of early‑20th‑century factories. It shows how a humble household product became a cornerstone of British industry, tracing its origins from ancient Gaulish mixtures to the modern, chemically informed processes that dominate today’s production lines.

The text balances scientific detail and practical instruction, assuming only a basic familiarity with chemistry while still serving the needs of seasoned works’ chemists. Readers will find thorough explanations of raw‑material selection, saponification reactions, temperature controls, and the dual measurement systems (Centigrade/Fahrenheit, Baumé/Twaddell) still used on the shop floor. Richly illustrated diagrams walk the listener through each stage of manufacture, making the complex chemistry of fatty acids and metallic bases accessible to anyone curious about how everyday soap is created.
