Humidity And Condensation Question

[Bencld]

Hello all. 

 

Just a quick question. 

 

Under what conditions would condensation form on a sword ? ie. moving from a cold room to a warm room, actual atmospheric humidity etc. I always have my blades lightly oiled with machine oil. What else can I do to mitigate the risks ? 

 

Thanks in advance.

It would have to be a really cool room moving to a warm humid one. If naked for viewing always clean and oil if necessary before replacing. They aren't that fragile, Japan in places at times is like being in a Turkish bath and these lasted hundreds of years with some TLC. John

Living in a high % humidity location, I found that even kept in a vault in a secure area, the swords were at risk, over the years; even with the best intentions and oiling.

 

My solution and success, was DampRid, which is easily available at Home Depo,  Loews, etc. You will be amazed at the moisture the container draws from the air.

Hi, it has something to do with the Dew Point.

Not sure if this is valid for metal surfaces but shouldn't it be possible to make a chart showing the dangerous min. temperatur of a blade at various room temperatures and relative humidities...?
