A Text-book of Tanning / A treatise on the conversion of skins into leather, both practical and theoretical.

A practical and theoretical handbook presents the anatomical and chemical structure of hides, the nature and analysis of tannins, and the selection and use of commercial tanning materials and water. It outlines laboratory methods useful in the tannery and gives stepwise manufacturing procedures for preparing, unhairing, tanning, and finishing sole and upper leathers, with detailed treatment in tan-houses and drying-sheds. Later sections describe dressing and currying methods, processes for enamelled, morocco, Russia, chamois, mineral-tanned, calf and glove-kid leathers, and guidance on tannery construction and maintenance. The volume closes with trade statistics and a practical bibliography.
