Howdy Sisters and Brothers,
In the sunnier months, im sure most of us become frenetic with activity. None is more true than my family trying to make the most of the summer. In my offline reading while camping i recall a thread questioning bronze and its ability to resist corrosion. Should one be worried about humidity and water bottle cutting with your bronze. Given the exposure of a bronze sword to the elements should one be worried about lowered performance.
Subject: bronze shorty from yonder classifieds. (Thanks to fattylumpkin )
Method: unscientific, neglect, no controls
Details:
I occasionally take swats at bottles with various members of my arsenal. I can be good (katana, saber) or bat things around (katana, saber). Mostly I use my production katana. After one particularly good session i went to put the blades back and left one on the outdoor rack.
It so happens that i didnt notice because its a bronze shorty and she blended right in with the wood of the deck.
Fig 0.0 The subject, a bronze short sword
Camping came about and for 2 weeks during the worst rain and wind Ontario could offer there it sat absorbing it all. Stalwart against the passage of time as any nullentropy case could offer; the patina it had naturally developed must be retarding the effects of wind and weather.
Fig 0.1 blade only
Upon inspspection, there wasnt a spot of verdigris or corrosion of any type. Undaunted, the blade went back on the rack for 2 more weeks. Below are shots of what happened.
Fig 0.2 slight haze
A slight haze had begun to develop near the makers engraving. Its a light haze but does not rub off nor wash off with water.
Fig 0.3 single spot
A single spot of what i might characterize as verdisgris appeared and grew after a month in the elements.
Fig 0.4 Compared to 2 years in the Canadian elements.
The bronze sheet-jug used for this experiment came from a local foundary so i know the composition and 'artist' and its lived in the same elements as the bronze shorty but its been there for 2 years.
So, it appears that once the natural patination begins with the bronze or is forced (mmm yes, bronze can be forced black:gunblue will do it. Ammonia fume baths will force a patina and colours, so will soysauce, salt and water misting etc so environment maters) it will resist developing corrosion (in my geographic area at least) for at least a month before anything visible springs forth. If youre carrying a bronze khopesh or shortsword or axe/tool etc, youre going to look after it in the field.
I can see no issue with standard cut and clean practice. If you want to force a bronze patination, check out youtube. Look especially for cat pee patina
Cheers!
