(Italian: “thousand flowers”). In glassmaking, a technique that produces complex decorative patterns. The technique begins with production of a glass cane with multicolored patterns viewable only from the cut ends of the cane. The cane is heated and pulled until thin, then cooled and cut into discs. The discs can then be re-heated and fused together in a mold. Web resource here.
