Glass mosaics are decorative artworks made by assembling small pieces of colored glass into a larger design. These pieces, known as tesserae, can vary in size, shape, and color, allowing for intricate patterns and images. Glass mosaics are often used in both indoor and outdoor settings, such as in churches, museums, and public spaces. The technique of creating glass mosaics dates back to ancient times, with examples found in Roman and Byzantine architecture. Today, artists continue to use this method to create stunning visual displays, combining traditional craftsmanship with modern design elements.
