Original Message:   Re: So-called "African Amber"
The combination of the specific gravity test (brine) and the static electricity test should be sufficient to identify amber except for the rare piece of copal which might pass both tests. Why is the hot needle test necessary?

Isn't the static electricity test valid for jet as well?
