The famous reference source H. R. Procter, The Principles of
Leather Manufacture, explores chemistry and the processes undertaken in the
manufacture of leather. Starting with a general overview relating to the
historical background and introduction concepts in leather manufacture, it
points to where the role of the living cell plays, the causative agents for
putrefaction, and also to antiseptics and disinfectants. It also covers the
chemical content of hides, the structure and growth of skin, and the
chemical processes by which it gets tanned - alum, chrome, and vegetable
tanning. The book also goes into the matter of physical chemistry of the
fibers of hides and water treatment in tanneries and methods for depilation,
deliming, and bating. The book is very valuable for any readers interested
in the chemical processes involved in leathering, giving both theoretical
knowledge and some practical insight into the tanning industry.
Lecture note on earth material:
Fundamentals of earth materials, strategic minerals, metals, and their
geochemical importance and significance Earth materials-Atoms and elements,
elements and their formation in the universe, cosmochemistry Chemical bonds
that characterize Earth materials with symmetry, lattices, point groups, and
space groups. It further discusses metamorphic petrology, which is rich in
dealing with the processes and transformations that occur in Earth's crust.
The resource is also important to students of geology, mineralogy, and other
related courses for it provides an overview of the material composition and
structure of the Earth.
