What Is Sea Glass? This Former Trash Is Now Treasured By Collectors, Artists
What Is Sea Glass Also Called?
Sea glass is actually known by several names. It’s sometimes called mermaid’s tears, sea gems or beach glass, as well as some other names. While they can be synonyms, some collectors believe that sea glass and beach glass are separate things: They say sea glass is found in saltwater, and beach glass comes from freshwater.
According to a story from MarthaStewart.com, glass found in lakes and rivers is usually smoother and more translucent, while the shards found on ocean shores will have a signature frosting. The salt in the water contributes to the pH levels that give sea glass that frosty look. Additionally, MyModernMet writes that the frosting comes from additives used during glass production being dissolved by saltwater.
