A glass mosaic is an art form that involves creating images or patterns by assembling small pieces of colored glass. These pieces, known as tesserae, can vary in size, shape, and color, allowing artists to produce intricate designs. Glass mosaics are often used in decorative applications, such as murals, tabletops, and architectural features. The technique dates back to ancient civilizations, including the Romans and Greeks, who used glass mosaics to adorn public spaces and private homes. Today, artists continue to explore this medium, combining traditional methods with modern techniques to create stunning visual works that can be found in galleries and public installations.
