I back lit the marbles with lines and it turns out they weren't lines at all; in fact they weren't anything at all---they were totally clear glass, with no coloring at all. They sure looked like lines at first glance, but as I said, the process of back lighting them proved it was simply clear glass. So, my bad. Thanks for all who answered. jaymib

I'm a newbie and want to know what the black lines found on some marbles mean. I'm not talking about Vitro's "All Red" circling. I'm talking about the thin dark lines that look like permanent marker scrawl. Are these lines count as a black color when you are counting a marble's colors. I appreciate all asistance. Thank you. jaymib
