The manufacture of earth colours : $b With thirty-one illustrations

"The Manufacture of Earth Colours" by Dr. Josef Bersch is a scientific exploration into the world of natural pigments sourced directly from the earth, originally revised from a version by Prof. Dr. Wilhelm Bersch. It examines the characteristics, sources, and uses of these pigments, pointing out their importance in both art and industry due to their long-lasting nature and affordability. The book starts by explaining the purpose of the work and recognizes the challenges of depending on limited natural resources, while setting the stage for a classification of the pigments into categories and discussing how they are processed, thereby providing a background for the following chapters that focus on specific types of earth pigments and their preparation methods.
