The glue book

A practical manual explains the production, testing, selection, and application of animal-based adhesives. It outlines raw materials and the boiling and drying methods used in manufacture. The text details tests and grading techniques, from simple water-absorption or jelly assessments usable in the workshop to laboratory analyses. Hands-on glue-room guidance covers soaking, controlled melting temperatures, indirect heating, cleanliness, storage, and handling to reduce waste. The work concludes with recommendations on equipment and guidance for choosing glues for woodworking, veneering, bookbinding, leather goods, and waterproofing, emphasizing economy and effective practice.
