 So I believe the most reliable way to identify ivory is by examining its structure under a magnifying glass.

 I was thinking about some different materials, you are quite correct.  Call it a brain cramp.
I did recently scrape some material and torched the bits and it did smell like a visit to the dentist.  That was on a painted ray handle.
