Sea glass is physically and chemically weathered glass found on the beaches of our Long Island’s salt water. The weathering processes produce natural frosted glass.  Sea glass takes 20-30 years and sometimes as much as 50 years to acquire its characteristic shape and texture.

Sea glass begins its life as normal shards of broken glass that are then persistently tumbled and ground until the sharp edges are smoothed and rounded.

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.

Beach Glass comes from fresh water and in most cases has a less frosted appearance and does not require the same length of time to produce its natural frosted glass look.  Beware of the Artificially- produced glass, it does not originate from the sea and a true sea glass connoisseur will not consider this glass, as sea glass.





The color of sea glass is determined by its original source. Most sea glass comes from bottles, plates, windows, windshields, ceramics or sea pottery.


Kelly Green, Brown, and White (clear): These colors come from bottles used by companies that sold juices, beer, soft drinks, windshields, plates and glass windows.


Less common colors include: Amber sea glass is from whiskey, medicine, spirits and early bleach bottles….Golden Amber sea glass is mostly spirit bottles…Lime Green sea glass is usually from soda bottles from the 1960’s…Forest Green and Ice-or-Soft Blue sea glass is from soda bottles, medicine bottles, ink bottles and fruit jars from the late 19th and early 20th centuries.  These are much less common to find.
