Scagliole (from the Italian Scaglia, "scale"), also called marble stucco, is a technique for producing columns, wall coatings, table inlays, sculptures and other architectural elements in stucco imitating marble, originally from Italy. It is a composite substance based on selenite, glue and natural pigments, imitating marble and other hard stones. The material can be veined with colors applied in the mass. It is polished with linseed oil for brightness, and waxed for protection. The combination of material and techniques offers a complex texture, and a richness of colors not available in natural veined marble. This technique, widely used in Italy since the 16th century, was intended to replace the costly use of colored marble. These lamps are a rare example of the use of scagliole for this type of object.
