Colour Case Hardening of Firearms--Principles and Practices

This is the first book intended to introduce both the theory and the basic practices that are used to case harden and colour select firearm parts. It will be of value to artisans making or restoring fine firearms, to collectors of fine firearms, or to those who are interested in having a fine firearm restored to its original appearance. Chapters are laid out in the actual sequence used to case colour parts. Additional chapters cover alternative finishing principles, such as patina application, products used to protect coloured parts and on the subject of charcoal blueing.
