Hi all,
I have a second hand Hanwei Shinto Katana that I have obtained in the last month or so. Because the sword is second hand there is a fair amount of spots where due to handling the brown patina has been rubbed off the fittings. This is effecting the tsuba, fuchi and kashira.
I am familiar with gun blue but I am unsure as to what product I could use to re-patinate these fittings. Any suggestions?
Thanks!

Over at MyArmoury is an article on aging and browning. The OP used ammonia. Place the object in a fuming box of some kind, a Tupperware box comes to mind, with ammonia on the bottom and the objects placed on supports so they do not contact the liquid. The fumes will do the work. Depending on temperature in about 2 - 3 days the objects will have a nice brown patina. The longer the darker. Clean off the blue green oxides with hot water, soap and a soft brush, dry in an oven on 100 degrees, cool and wax. This works well on copper and bronze fittings. For rust brown on iron use a mix of vinager with some water in a spray flacon. Place the object on some support in a tub of water to create a moist environment. Spray the object lightly, so the liquid does not run off. Do this for a couple of days and the iron will rust. When dark enough clean off lose rust and wax or coat. You can also dunk the object in ,,Eau de William''. That was the way scabbards were done in the old days. With ,,Eau du Regiment''. The best and toughest finish there is. See sbg-sword-forum.forums.net/thread/46663/french-m1822-light-cavalry-artillery for an example. What ever you do, clean the object very well before any process and do not touch with fingers. Cheers.

Before starting make sure that all oil/grease are removed and afterwards do not handle with bare hands. Also if working with acids such as vinegar (acetic acid) washing with a buffer solution such as baking soda afterwards will stop any further action which may result in red rust.

Is that birchwood brown a liquid or gel? I am looking for a gel as I cannot get the kashira off without partially dissembling the ito. I may do that in time anyways as the tsuka is a bit too long.
