One way is with a hot pin, this will tell you if it is plastic. A pin hot enough to burn pushed on a discrete place of an item in question when applied will soon tell you if it's plastic from the smell of the smoke. This will not differentiate it from bone. This can be done as ivory has a distinct very fine grain (as with woods). Bone however does not and often has small holes left where blood vessels were, whereas ivory has no blood vessels through it. It can still be difficult where niether of these distinctions are apparent and is difficult to demonstrate without pictorial examples to show.

Plastic and resins are usually smoother than real ivory. Looking at bone under magnification you will see a lot of pitting something that real ivory will not have. The hot pin test can help you determine the difference between plastic, synthetic, bone and ivory. Its best to perform this test on the bottom of the object that is not visible as it may cause damage to plastic objects. Heat a needle until it is extremely hot than touch the needle against the object you are testing. A hot needle can not penetrate real ivory like it will a plastic or resin. When you touch bone with a hot needle smell the area that you touched. It should have a very unique smell like burning hair. When you touch ivory with a hot needle you will smell something more like a burning teeth dentist office type smell. Passing this test is a pretty good indication that you have real ivory.
very hot
No it does not.
IQ booster survey pin number?
hot wire

The READY pin is used to synchronize memory, and is applicable to every memory operation. The TEST pin is used to synchronize external logic and is specific to the WAIT instruction.
In North America the neutral pin is used to complete the circuit. One pin is "hot", one pin is neutral and the last pin is ground.
You solder ground to pin 1, hot/plus to pin 2, cold/minus to pin 3
