Glass buoys are floating devices made from glass, often used in maritime activities. They serve various purposes, such as marking fishing areas, navigation routes, or hazards in the water. Their bright colors and reflective surfaces make them easily visible to boats and ships. Historically, glass buoys were crafted by skilled artisans and were often hand-blown. Today, while many buoys are made from plastic or other materials, glass buoys remain popular among collectors and are sometimes used in decorative applications. They are often associated with fishing, nautical decor, and coastal art.
