I read about Ivorine in the last MMDigest 981222.  Is it an
artificial ivory?

If it is, and it is no longer produced, this is an address where
you can order artificial ivory of a good quality, available in rods,
sheets and discs, non toxic also :

The documentation I have is from 5 years ago.  Telephone numbers may
have changed a bit.
