Traditional Damascus rust brown finish
One of the jobs we get to do from time to time is a Traditional rust brown finish on Damascus barrels.
This is the old method of bringing a deep and pleasing brown finish to the barrels which showcases the pattern welded detail of the barrel construction.
The process is very labour intensive and takes some considerable time to complete, often dictated by the type and quality of the iron and steel combination of the barrels being treated. The whole process from start to finish needs to be kept on top of, otherwise it's back to square one.
This is a job from the old methods of gun making, and is rarely undertaken because of the costs involved, but is so much more durable than the chemical processes which have replaced them.
