Why are some sea glass colors common and some rare?


Some sea or beach glass colors are common and easily found, while other colors are extremely rare. Why? Read on to find out!



A brief look at the history of sea glass explains this.
Glass was first made possibly as early as 1730 BC in Asia.

Glass is made from silica (historically in the form of sand) and alkali or soda ash (sodium carbonate), which can be extracted from the ashes of many plants. These two ingredients were melted together to form early glass.

This process, which makes soda-lime glass, is still the basic process used in making glass today.

When was colored glass first used?

Until the 12th century, colored or stained glass was not widely used.

To make colored glass, first a small or large amount of a natural coloring agent (such as metallic or other impurities) was finely ground and then melted with the glass. Many of these coloring agents still exist today.
What makes the different colors?

Clear (white), as we know, is made with soda-lime. To produce colors the following minerals alone or combined with other minerals produce the following colors glass:

COLOR PRIMARY MINERAL
Bluish-green (beer and wine bottles) Iron
Amber, yellow, and near black Sulphur
Amethyst and purple Manganese
Red and pink Selenium
Blue Cobalt
White (opaque) Tin
Turquoise Copper oxide
Dark red (opaque) Pure metallic copper
Blue, violet, purple, and black Nickel
Ruby and cranberry Metallic gold
Fourescent yellow, green, and red Uranium
Orange-red to yellow Silver



As you can see, some of the beautiful colors involve not only much more costly ingredients, but the process involved also may cost significantly more to produce deep vibrant colors and so has generally only been used for limited production.

Naturally, these are the most vibrant sea glass colors and also the most sought after by collectors for their sea glass collections and sea glass jewelry.
