I am fascinated with sea glass. It started when I began making jewelry. My walks on the beach turned into a mission to find sea glass, or rather, inventory for my small jewelry business. But it’s not all about inventory anymore. On the beach at Pine Knoll Shores I found part of a Pepsi-Cola bottle. (The picture speaks for itself.) Last year on Hatteras Island I found a rare piece that I believe was once part of an old Clorox bottle. Hatteras seems to be the place for rare and interesting finds. This year I found a piece of cobalt blue glass – the color is rare in itself which also made it easier to spot. The piece has four legible letters: RE, MD. And so I researched it. I learned the letters are actually part of “Baltimore, MD” and the glass originated as a Bromo-Seltzer bottle from the Emerson Drug Company, Baltimore, MD. The year of this piece is questionable, but after looking at pictures of Bromo-Seltzer bottles on various websites, and considering the condition of the glass, my best guess is that this piece is circa 1940 to 1950.
