Yes, black sea glass is considered rare, ranking as the fifth most rare sea glass color.
While commonly referred to as "black glass," this unique form of sea glass is not truly black. When held up to the light, black sea glass reveals its actual color, which is a very dark olive green. Its perceived blackness is due to the deep saturation of its original color, making it appear opaque.
The Rarity of Black Sea Glass
The scarcity of black sea glass contributes to its appeal among collectors. Its ranking as the fifth most rare color means it is less commonly found compared to more prevalent colors like clear, brown, or green. This rarity stems from its historical usage and the specific timeframes during which it was produced.
Historical Context of Black Glass
Black glass, or the very dark olive green glass, has a long history, dating back as far as the 1700s. It was widely utilized for practical purposes, primarily for beer and liquor bottles, due to its ability to protect contents from sunlight. This common usage continued up until approximately 1870.
The production of these dark bottles declined significantly after 1870, making genuine black sea glass from this era particularly valuable and increasingly hard to find. The limited period of its widespread production, combined with the natural processes required for glass to transform into smooth, frosted sea glass, explains its rarity today.
