preservation of japanese armor

During my last 2 trips to Japan, I saw several sets of armor that I saw decades ago in Europe. Despite the fact that many Japanese people believe that their works can only be stored in their own country, I found to my surprise that many of those pieces were seriously damaged during their stay in Japan. Either the lacing was completely mortified by exposure to light, or the ironwork was rusted through a maladjusted humidity.

I try to do anything possible for a good preservation, not only for myself but also for future owners of my collection.

Personally, I keep everything in a totally dark room, with only LED lighting. The humidity is always between 50 and 60%.

All tips are wellcome!

Luc,

I have my armor in a glass case, the glass is UV filtering and I have LEDs in the case, they are only on when I want to view it in detail. The case buffers the armor from rapid weather changes, heat or cold, and helps maintain the humidity. I keep the case at 45-55% in the summer, and it is not easy...

In the winter I run a humidifier in the same room as the armor as the humidity will drop to 18-25% in the room with the gas heat I have. The humidifier will increase the room to 40% max, so the armor case will drop to 40% in the winter.

I live in a stone house.

I keep the armour in a dark room with no sunlight or heating.
