Sbruffo is a distinctive Murano Glass design, which features rough-surfaces and multiple colors layered on top of each other. Sbruffo objects are made by putting layers of blown colored glass on top of a glass core, then breaking them off until just a thin and rough colorful layer on top remains. This process is then repeated over and over, until many rough layers are put on top of each other, creating an impression of flowing glass. The rough edges are then polished off. Using multiple colors and unique forms, the masters make tumblers, glasses, vases, bowls, and sculptures with sbruffo designs, which are instantly recognizable as authentic Murano Glass. Only a few Murano Glass factories and workshops still create sbruffo art glass objects, and many interior design aficionados, collectors, and Murano Glass fans seek these objects of refined beauty and distinct Italian elegance.
