Sea glass can be thought of as a well traveled piece of history. The hard substances
that you find have spent a considerable amount of time floating in the ocean. It has been tumbling along the sand and water for so long that that the glass, slate or what have you, has been polished by the sand grains.
Usually the brightly colored pieces are collected quickly by beachcombers. If you spend time investigating the wrack line you will surely discover some more subtle pieces – if you are lucky you will find some with faded descriptions of their original containers.
