There should be more warnings about the possible effects of reflected sunlight, Krysia, especially during the sort of weather we're having at the moment. A few years ago, I noticed that there were one or two black spots burnt into the surface of a pine desk that is located by a window in my flat. I realized that they were caused by sunlight being concentrated through a glass paperweight on the desk. No great harm done, but in different circumstances, the results could have been much more serious.
