Hello all,
Nathan Scott recently posted a thread about a yari he had restored. It got me thinking about some projects I've been meaning to work on. I've had this tsuba in my collection for about 20 years and i have always liked it. The biggest problem with it though is that some well meaning knucklehead thought it would be better spray painted gold. Not such a good plan.
Dr. Richard Stein helped me identify the tsuba as Onin style, so named after the Onin era (re: Onin War) during the Muromachi period. The style of tsuba was popular for about 50 years before the Onin era and for another hundred or so after the Onin era but the style really came into its own during that era so that is why it is named that.
My first task was to remove the gold spray paint. I used some acetone and an old toothbrush to really work it off. I then had to deal with some red rust (not that much really) and some old nasty crud. We're looking at about 500 years of build up so it was gross but not too bad. When removing this old red rust and debris you need something hard enough to get it off the iron plate but soft enough that it won't damage the old patina. Ivory, antler, bamboo and some woods are popular materials to make scrapers. I went with bamboo because I have access to a lot of chopsticks ^_^
Anyway with some time and love I got the worst of it off. I then took to rubbing it with a piece of old tee shirt until it started to get a little bit of the luster back. After getting a lot of the old paint and crud off I found that the brass was more polished than I had thought (I could never tell what was polished and what was paint previously). My next task will be to get a nice golden brown patina on the brass.
Years ago I had read an old time collector mention that one of the best ways to patina old soft metals like brass and copper was to leave it in the bathroom near the toilet and shower for several weeks (a mix of the gases from the toilet and the dampness from the shower helps the metal patina... gross I know). I had an old tiger menuki made of shakudo; the tiger's stripes were made of gold. Someone in the past thought that it was too dull and shined it right up. Not a good idea. So I placed it in the bathroom and left it there for a couple months. When I went back for it the shakudo had turned a rich redish/purpleish black and the golden stripes were very clear. I think this might help me get the effect I want out of this tsuba.
Sadly there is a little bit of brass missing from the omote side near the top. Also at one point the brass wire had a rope pattern cut into it. Age has worn away most of the rope pattern. It can still be seen in a few places though.
Anyway here is the progress I've made so far. Feedback is welcome!
Best regards,
Chris
