Murrine is a decorative glass technique that involves creating intricate patterns by layering colored glass rods. These rods are heated and then stretched, resulting in a cross-section that reveals the design. The process allows for a variety of shapes and colors, making each piece unique. Once the rods are prepared, they can be sliced into thin sections and used in various glasswork applications, such as glass beads, paperweights, or jewelry. The beauty of murrine lies in its ability to showcase detailed images and patterns, making it a popular choice among glass artists and collectors.
