Methods of differentiation between the ivory and bone:
First: the detection of the advantages of real ivory Real ivory
features some features that make it different from the bones, as it is known for its density and weight, so can be tested by the hand and feel the weight of the weight of the hand, where If a person feels the strength and strength of the ivory, it is more likely to be an original piece of ivory, but sometimes the bones are too heavy to be compared to other pieces made of ivory.
The fingers can be passed on the ivory to feel the touch and reveal it.

The original ivory has a bright and beautiful appearance, but it has a thin yellow layer. It's surface over the years where it will be noticed the presence of some dark spots on the surface of the piece.
You should also look at the cross lines on the piece, where lines should appear parallel to the length of the piece, and there should also be other orthogonal lines on the first lines, to appear as a letter V and call these lines the name of "lines Schreger", and from Can be observed on ivory ivy and mammoth, as well as the presence of bone marrow or minor scratches if found, it is evidence that it is a piece of bone .
Second: Hot Pin Testing
This test can be done to detect the fact that the pin is heated by passing it on a candle flame or lightening it. Make sure it is well shot and the pin can be replaced with a metal piece. The best option to do this test, the pin is placed in a specific spot of the piece of ivory and then that spot is sniffed.
If the denture is real, it will not smell any new, but if it is made from the bones it will smell a light smell similar to the smell of burning hair, nor does this experience any harm to the original ivory because it has the strength and strength and can resist heat, but if The piece was made of plastic and will show a longitudinal spindle that will damage this piece.
