I'm trying out a new way to test for authentic tortoise shell and was looking for some more help! With the current help from Thaeris I know that tortoise shell and translucent horn (fux horn tortoise shell) both glow under black Light. I'm hoping use this information as method to distinguish between authentic and fux tortoise shell (celluloid, acrylic, and other vintage plastics). Horn and tortoise shell I have already tested ( with the help of Thaeris!!) as well the the fux tortoise shell from maze craft supply but I'm having trouble sourcing the Vintage stuff if you have and are willing to shine a blacklight on some of your vintage fux tortoise shell I would love to hear your results!!


Current results are

Tortoise shell- glows
Fux horn tortoise shell- glows
Any translucent horn- glows
Black horn- no glow
Maze craft supply fux tortoise shell- no glow

This thread should be more help to the people who are new to tortoise shell!
