    I am pretty ignorant about chemistry, someone please explain why the
    dictionary says that ether is 1) C2-H5)2O, obtained by distillation
    of alcohol with sulfuric acid 2) any of various organic compounds
    characterized by an oxygen atom  attached to two carbon atoms and
    that Liddicoat says that separation of copal from amber can be done
    with ether, and I posted the chemical composition of acetone, which
    is close to the same composition as ether, and there seems to be a
    lack of understanding that there is a gemmological test that is
    correct until proven not to be so. 

    If you do not know what you are testing, and do not know how to
    separate plastic, amber, copal, or any substance, your method and
    conclusion does not mean anything.  

    I have done it. More than once. It means that if you do what I did
    with known stones of amber and known stones of copal, you get the
    same results I do, and it is in accordance with known gemmological
    testing. 

    I recently, before I made my last post, put three cabs of amber in
    acetone, and left them for 48 hours. They lost their polish, they
    got flexible. They did not dissolve. Not a little bit. 

    I am trying to help educate others based on posts of members that
    are trying to discern what something is, using my gemmology
    education, which I spent 6 months, 5 days a week, and 8 hours a day
    to acquire. 

    What I post is not assumption or speculation. It is fact. Facts
    don't change. 

    Gemmological testing is determining what something is not, exclusion
    of everything that indicates what it could not be, resulting is the
    only thing it could be. 

    Testing includes microscope, spectra, determining whether it is
    singly or doubly refractive, RI, specific gravity, uni or bi-axial,
    refractive liquids, internal characteristics, ect.
