Everyone thinks marbles are so very rare. Here is a handful of some of the sea glass marbles I have found in the last several years. I wish I had pictures of all the marbles I have found walking the beach, I have actually found over 20. I've found them to be more common than red sea glass. And orange sea glass, I have yet to find any in all the years I have beach combed.
There are many reasons why marbles end up in the waters. They are not only a child's toy!
They were used by painters to help mix paints, similar to the theory when you shake a paint can today...
Marbles were also used to ballast a ship crossing the seas.. the ship crashes and sinks and so do all the marbles and they make their way on the beaches.
In England they used marbles as a bottle stoppers back in the 1800's.
Marbles were more than just child's play back in the day, now they are a piece of history washing up on the beaches!
