River glass refers to pieces of glass that have been naturally smoothed and polished by the action of water in rivers or streams. Over time, the glass is tumbled by the current, which removes sharp edges and creates a frosted appearance. This process can take many years, resulting in unique shapes and colors. Often found along riverbanks, river glass is popular among collectors and artisans. It can be used in various crafts, such as jewelry making or decorative art. Many people enjoy searching for these treasures, as each piece tells a story of its journey through nature.
