When you find a piece of sea glass on the beach, do you ever wonder where it came from? In my mind, I always create a story around the glass - was it part of a pirate’s shipwreck or a bottle of wine shared by lovers on the beach? The mystery is part of the allure…
Let’s talk about teal sea glass, sometimes called turquoise. Have you ever had the luck of finding a piece this color? This shade of sea glass is one of the rarest. Only one in 4,000-6,000 pieces of sea glass that beachcombers find are teal.
This color of glass was produced in small batches before the 1950s, and has been in production for over 3,000 years. In order to make this glass, makers had to accurately blend the right proportions of cobalt, iron, and chromium to get its color. It was so hard to produce a consistent color from batch to batch that it wasn’t widely produced. Hence why it’s so rare to find a piece of this sea glass.
Originally, teal glass was mostly glass seltzer and mineral water bottles, wine bottles, ink and baking soda bottles, glass insulators and early hot sauce bottles. The older the glass is, the more bubbles you’ll see inside of it. If you hold your sea glass up to the light, you can easily see if it has bubbles.
Since the blend of ingredients was so delicate, the different shades of teal sea glass range a lot. When you compare the different pieces of turquoise sea glass, it’s easy to see the slight differences in shade. This sea glass color is rare, but easy to spot on the beach when combing. And when you do find it, celebrate! Because it’s truly like finding a piece of treasure.
