I have been thinking of asking this question for a long time, and have been reading about average and recommended humidity levels, but since my studio is in my apartment where i live, and we have radiators in every apartment in the building i find it very difficult to set humidity that is recommended...
During the spring, summer and even some parts of autumn the humidity is usualy about 40-55 % . I have read that these are actually solid, ok humidity levels.
But during the cold autumn days and during the whole winter, the city starts turning on the heating and the radiators begin working.
Temperature is usually set in whole building, so in every apartment is pretty much the same temperature, around 25°C .
Then the humidity levels drop up to 12-22 % .
I was really worried when i saw that the humidity drops up to 12%.
I wanted to ask, do you think that low humidity like this represents a big danger to paintings( oil, acrylic, egg tempera) and watercolors, gouache paintings, also drawings....?
If it does, how can i fix this problem..?
Or are these strict rules meant for very old artworks that need extra museum care..?
I try to do best for my artworks, and to take care of them as much as i can, but whenever i start worrying that much, i cant help but to think how many old artworks survived in old houses, old studios, in some military storages during wars, and back in ancient times when i believe artists didn't knew much, or maybe anything about humidity levels...?
Your answers are much appreciated!
