Ken-Hawaii Posted July 7, 2017 Report Posted July 7, 2017 http://www.ebay.com/itm/Sukashi-Tsuba-Flower-Japanese-Antique-Katana-Sword-Koshirae-Wakizashi-Tosogu-Edo-/292175047578 Has this tsuba been in a fire, or is its poor condition caused by water damage? How can one tell? Ken Quote
Bazza Posted July 7, 2017 Report Posted July 7, 2017 IMHO sheer neglect (edit out) in a Japanese forgotten place with humidity... BaZZa. Quote
ROKUJURO Posted July 8, 2017 Report Posted July 8, 2017 Ken,what we see is heavy corrosion, but this may well have been accelerated by a fire, I think. If we look at the SHINCHU, it is also damaged in places, but rust would not have affected it. The melting intervall of brass is roughly between 950 and 1.000°C, so a damage by fire is likely. Quote
Ken-Hawaii Posted July 8, 2017 Author Report Posted July 8, 2017 Thanks, Jean. Do you see signs of the shinchu melting? That's what I looked for, but it seemed that any brass damage was more related to excessive rust than to excessive heat. As BaZZa says, it could have easily sat in high humidity for centuries, but the rust sure looks deep for just that. I'm trying to get a handle on why the iron would almost disintegrate like this.

Akao Posted July 8, 2017 Report Posted July 8, 2017 I take advantage of this topic : why is there so many tsuba been in a fire ? It was an old restoration technique ? Thanks Quote

It was an old restoration technique ? Thanks As far as I know, there is not so many tsuba been in fire and it is not an old restoration technique. Traditional japaneses houses are in wood, so very sensitives to fire due to accidents, wars, ... Quote

But the damage of the brass is somewhat strange and not typical. An inlay piece might fall off as a whole, but it should not be damaged partly by rust, I think. On the other hand, Ford is the man to comment competently on this subject, Quote
Ken-Hawaii Posted July 9, 2017 Author Report Posted July 9, 2017 If a tsuba was immersed in saltwater for a century & then left sitting around, this is how I'd picture the result. Ken Quote
