I have a question about the dark staining that occurs on my wooden spectacle frames where they rub constantly with my skin around the ears and nose. Can anyone tell me what is causing this? And could it be reproduced artificially?
I think you can see what I'm talking about in the photo. (Excuse poor image quality).
I make the glasses, and one of the difficulties is finding a good way to stain them - dark frames suite many people best but the woods from around here are mostly light. If I could only make them go dark like they do from rubbing with skin. But all over. That would be perfect. Anyone think it could be done?
