Question about marbles

[Immy]

I always see people finding marbles with their detectors. How do MDs "detect" them? They're just glass right?

I found one and it just happened to be in a scoop i brought up with some iron. I think its just luck!

I've eyeballed them on the surface before, after a good rain at old homesites.

I know i have found a bunch while digging bottles. I found this real nice bottle dump and had made a fast make shift sifter that while digging i would throw the dirt into. I found marbles,coin,tokens,small bottles,buttons etc
