"The Determination of the Acidity of a Tan Liquor" is a specialized technical study focused on the chemical analysis processes essential to the leather tanning industry. Written by Ernest Little, this work addresses the critical need for precise measurement of acidity within tan liquors, a factor that directly impacts the quality and durability of the final leather product.
The text provides a detailed examination of various analytical methods used to establish the hydrogen ion concentration and total acidity of tanning solutions. It explores the chemical properties of vegetable tanning materials and the interactions that occur during the tanning process. By evaluating different titration techniques and indicators, the work seeks to provide leather chemists and industrial manufacturers with more reliable and standardized procedures for process control. This volume serves as an important historical reference for the development of industrial chemistry and its application to traditional manufacturing crafts, offering deep insights into the scientific rigor applied to the production of leather in the early twentieth century.
