    Blue Bowl is it gold or something else?

    I have a bunch of super small shiney specks in the bottom of my blue bowl after all the sands are gone. Could they be anything other than gold? The cons were 100 mesh a loaded with pyrite or something simular. How do I know for sure if it's gold. Is flour gold too small for metal detectors?

    its probly gold! as far as most detectors go, yep they wont pick it up. but maybe a Falcon 10 or a Falcon 20 will pickit up.

    Thanks for your reply. This 100 mesh stuff seems to take forever but I think the blue bowl might be the best bet. Not sure if it is worth the time. Going to try building a chalk board miller table next for my super fines. Good Luck

    Could it be something else? I occasionally find shiney black and gray bits. Any way to tell if its platinum or silver without serious analysis?
    thanks-

    How effective is your slate (chalkboard?) Miller table at getting all your fines & super fines.

    In a clean pan, throw in some of the black & gray bits along with some similarly shaped/sized fine gold and and see how they move in relation to each other.

    Platinum is heavier than gold, but not much heavier, but silver is only half as heavy and the weight of alloys depends upon composition.
    Sometimes gold is not yellow and the silver bits could be alloys.

    I get a lot of very fine silver/grey heavies which are far heavier than hematite and while I think a good portion of it is lead, I've been keeping them in a jar to send off for a melt if and when I ever get curious enough.

    Have you tried melting it yourself? Lead melts easily, silver is a bit more difficult and platinum is very difficult.
