This book will show you the different processes of blacking guns.
THE HOT DIP PROCESS
A little over a decade ago there were very few gunsmiths who thought gun blacking so easy a job that they should go out of their way to solicit work of that type. Today, however, it would appear that all the advertising gunsmiths are only too glad to take on blacking work in any volume.
ADVANTAGES
To fully understand why the hot dip process has changed the gun blacking business so radically is to realize that 10 or more pistols can be blued by one man by the hot dip process. This can be done in less time than it takes too blue one pistol by the misnamed quick method rusting process.
