What Is Sea Glass?
Sea glass, also known as beach glass, is a smooth and rounded piece of glass that has been weathered and polished by the action of waves and sand. It is a popular collectible, and can be found on beaches all over the world. "Genuine sea glass" can be collected as a hobby and can be used to make jewelry.
Sea glass is distinguished by its smooth, rounded shapes, frosted surface texture, and unique color variations. The color of sea glass depends on the type of glass it was made from. Common colors include white, brown, green, and blue, while rarer colors like red, orange, and yellow are highly sought after by collectors.

How sea glass is made?
Sea glass begins as normal shards of broken glass that are then persistently tumbled and ground until the sharp edges are smoothed and rounded. In this process, the glass loses its slick surface but gains a frosted appearance over many years.
Naturally produced sea glass ("genuine sea glass") originates as pieces of glass from broken bottles, broken tableware, or even shipwrecks, which are rolled and tumbled in the ocean for years until all of their edges are rounded off, and the slickness of the glass has been worn to a frosted appearance.
Artificially produced sea glass (sometimes called "beach glass"), although superficially similar to sea glass, nevertheless has clear differences in appearance. Having not actually originated from the sea, most connoisseurs will not consider artificial "sea" glass to actually be genuine sea glass, but rather simply tumbled glass, where pieces of modern-day glass are tossed into a rock tumbler or dipped in acid to produce the desired finish. Artificially-produced, the glass is much less expensive and is used for making jewelry, but is often passed off as real sea glass.

When to look? The peak time to search is right before or after a low tide; during full-moon periods, when tides are stronger; or after a storm, when currents may have stirred up long-buried lumps.
