Thread: Ivory vs Bone vs fake Ivory under Black light examples needed

Well, full disclosure, I'm part of one of Germany's most successful geocaching owner groups. We specialise in abandoned military installations, so our UV lamps are a bit on the bright side. I tried four of them, and, well, photographing the results wasn't fun. The results are, mildly put, poor. But I can assure you that if you hit ivory with a UV lamp, nothing happens. Well, the ivory develops a light greenish yellow shine, but that's that. If you see ivory, you'll know it's ivory, trust me. Bone is a completely different material. For good measure, I took pictures of ivory, celluloid, wood, and errrr... whatever that pink stuff is. I took the lamp with the highest amount of white light in order to be able to take any pictures, but even the "pure" UV lights didn't return any repeatable effects, ie this test is useless.
