Of course, that UV light might also be harmful to the paintings. TANSTAAFL, after all.
Well maybe but if I'm not mistaken most of the paintings were done with charcoal, crushed berry juices, even with colored mud/clay, chalk could've been used for the white. So am thinking that UV wouldn't cause them to fade... not unless it's on 10-12 hours a day like a painting out in the sun...
Good question ... wondered if they have thought about that. Or would a disinfectant (like lysol) would kill the fungus and still leave the paintings intact...
