    black light question

    Can anyone tell me what you are looking for when you put your marbles under a black light?

    Re: black light question

    Sometimes the glass used in making the marble might have some type of fluorescence to it. Some even had uranium in them until they outlawed it in glass. If you use a blacklight over the marbles (in a somewhat darkened room), you'll find that some of the marbles (or parts of them) 'glow' yellow or green (or maybe another color). I couldn't find a picture taken of blacklighted marble - maybe someone has one they can post to show what it looks like with and without?

    Well I put the marbles under a blacklight and there were several that had the fluorescent glow to them and a few really had a bright glow. There were alot of ones with purple in them to that you can not see without the blacklight. So does that mean they are older ones?

    Hi Gang;
    Here are some examples of marbles that "glow" under black light.

    Thank You all for the help and the picture. Now if I can figure out how to make my pictures smaller so I can send them as an attachment I will send more pictures. It's a new camera. lillav

    Just take your pics with the size set to smallest and quality the highest and they should be fine for posting. Peace,Galen
