Hi

Found this piece on a beach in Nahant,MA.

The blue color was the first thing I noticed when hunting.

Took home and after a soak and scrub the coating remained.

Have no idea what it could be, never seen glass like this on local beaches.

Any ideas? Thanks!

 Colonial Period Glass?
by: Siobhan O'Donnell

The first thing I noticed about your shard was the deep green (and some blue) color to it.

The second thing I noticed was the quality and grain of the glass itself. Judging by the color, and the fact that it is not one color, but a combination of two that was probably not on purpose, and the quality and wear of the Glass, I believe that you may have found a piece of colonial glass.

The area you found it also solidifies my stand. Massachusetts was one of the first colonies to begin attempting to make glass. The only problem was that they could not make glass the same way they had in Europe. They had to test local ingredients, such as sand, to find the right recipe to make acceptable glass. So they had to experiment around with the types of sands and other such things, leading to the dark green, impure glass often found along the east coast.

You can do some more research to find out more about it.

 Mineral deposits
by: David & Lin @ OdysseySeaGlass

We have found some pieces of beach glass that look very similar.

Those pieces were very old and were on a sandy beach on the Chesapeake Bay at the mouth of a trickle of a stream.

The lack of much wave action, we feel, left them in that area of the beach and the glass became coated with mineral deposits from the spring feeding the little stream.

Sunlight then reacted with the minerals to produce almost a rainbow sheen on the dark glass.

That is our guess, anyway. :)

 I have a similar piece.
by: Selkie's Sea Glass

I have a smaller piece that is a dark green like this, with a patch of blue on the corner.

My feeling is that it could be carnival glass, or simply a piece of art glass.

Happy sea glassing!
