Collection: Cobalt & Blue Antique Glass Bottles from NYC

Blue glass was a warning. In the 1800s and early 1900s, cobalt and deep blue bottles were standard for poisons, potent medicines, and anything that needed to be visually distinct from safer household contents, a color-coded system of danger that predated childproof caps by decades. The bottles in this collection were recovered from New York City beaches, where that same glass has been waiting in the sand for a century or more. Deep cobalt is the most sought-after color in antique bottle collecting: it has a jewel-toned intensity that catches and holds light differently than any other glass. Each piece is hand-selected for color depth and character.
