The Beautiful Shades of Blue Sea Glass

Blue sea glass is one of the most popular colors among sea glass collectors and enthusiasts. Blue is found in different shades like soft blue, aqua, cornflower blue, cobalt blue, and turquoise. Several jewelers and crafters use blue sea glass for their projects. Blue sea glass contrasts nicely next to other sea glass in different colors, and it also happens to look like the colors of the oceans.

Finding Blue Sea Glass is Rare

Much of the blue sea glass people find comes from bottles between the 1880s to the 1950s.

Almost all of the blue sea glass shards I’ve found along California’s coast are small–about the size of baby peas.

Most soft blue sea glass comes from soda bottles, beer bottles, and fruit jars. They could also come from windows, windshields, and other flat glass.

Cornflower blue sea glass is a little lighter than cobalt blue sea glass. It was used for Phillips’ Milk of  Magnesia bottles and decorative glass. Cornflower blue is much rarer than cobalt blue.

If you find a piece of turquoise sea glass, consider yourself lucky. It’s extremely rare. Some even consider it more rare than red sea glass. Most turquoise sea glass come from vases, decorative bottles, flasks, art glass, and seltzer bottles.
