Hi. Ivory vs bone is easy. Bone has tiny holes that you can see under magnification.
The "Hot wire" test is good for distinguishing between plastics and ivory though not all plastics will react clearly. Barring fakery, I would bet on ivory. Also, Ivory cracks as an almost natural occurrence, plastic does not except under stress. |
