Lampworking technique of glass-making, which dates back to ancient Egypt, was revived by Murano glass artisans around the fourteenth century. This technique is based on heating up a blob of glass under a small flame from a lamp or a torch until it reaches malleable state, then blowing and using simple tools or just hands to create various forms and designs. Lampworking allows the artisan's creativity to blossom, as copper sparkles, various minerals, and pieces of glass cane are fused together in this process to create rich colors and imaginative patterns that are always unique. Murano Glass masters often use lampworking method to create small jewelry, such as pendants, earrings, or rings, as well as keychains, barrettes, pillboxes, and figurines.
