Beachcombing may not appeal to surfers or sun worshippers who frequent the beach. But for those who like to see what treasures the ocean deposits on land, hunting for a sea glass beach in Maine can bring you great success.

These colorful collectibles are actually historical in nature, having spent many years in seawater depths. So finding a piece of sea glass can be quite satisfying.

Let’s look a little closer at sea glass and help you discover where to look for these gems.

What Is a Sea Glass Beach? 

An ocean beach where pieces of water-worn glass roll up on the sand is considered a sea glass beach. The glass usually comes from broken bottles that end up in the sea.

They’ve been tossed around for years, making their edges rounded and smooth. To qualify as “sea glass,” the glass must be in salt water.

Here, the ocean has not only physically changed the glass, but the salt has chemically changed it. Glass found in freshwater lakes is just considered “beach glass,” as there is no chemical alteration.

Is There a Sea Glass Beach in Maine? 

There are several beaches in Maine that consistently offer up sea glass. The Atlantic Ocean currents bring pieces of sea glass to shore after they have been tumbling for years.

Their edges become soft and rounded, and the original shiny, transparent glass has been chemically changed to a translucent luster. This makes the sea glass appealing to jewelry artists and collectors.
