I just got a call from someone who wanted to know if there was a test the perform on ivory that determines if it is real or not. If there is (which I imagine the is) will someone please enlighten me? thanks, Britney Britney Hager Collections Manager Dallas Museum of Natural History 3535 Grand Ave Dallas TX 75210 (214)421-3466 Ext. 205 bhager at dmnhnet.org
