Working for Scale
You've Never Seen Marble Like This
Scagliola, the venerable art of engraving intricate designs on slate or marble, is alive and well. Scagliola comes from the mineral selenite, a variety of gypsum that in its natural state appears in the form of thin plates or scales (thus the name scagliola, from the Italian word scaglia or scale).
After the mineral is cooked and ground to a fine powder, it is mixed with pigments of colored earth and glues to form a thick paste. The colored paste is applied into designs carved in slabs of marble or slate.
For elaborate decorative motifs, subtle gradations of color are added in diluted scagliola applied by hand with a fine paintbrush. Lastly, the slab is polished with polishing stones, wax, and lacquer.
Scagliola’s complex twists and veins go deep into the stone, providing a durable surface which is far more permanent than faux surfaces that are painted to resemble marble.
In the late 19th and the early 20th centuries, scagliola was also very popular in the United States. Artificial marble furnishings at that time were created chiefly by itinerant plasterers, men who kept the details of their fabrication process a secret. After the 1920s, however, techniques of fabrication were forgotten. Scagliola virtually disappeared from American architecture.
Today, the use of artificial marble has again revived. This resurgent interest is the result of four factors: a new appreciation of marble-like finishes, a dissatisfaction with the limitations that real marble places on design, the unavailability of traditional colors and types of marble, and the rising costs of quarrying.
Scagliola is inherently beautiful and can duplicate the appearance of any type of marble, and it can be molded into any shape. Decorative, three-dimensional motifs impossible to produce in marble can be fabricated in scagliola. Because the artificial stone is less expensive than its marble original, it is a particularly attractive option for interior design and decoration.
The premier practitioners of the art are the Bianchi family of Florence. Among their clients are the likes of the Agnellis, Prince Michael of Kent and ZaZa Gabor. But you too can have your own little piece of Bianchi scagliola—prices start below $500. Make an appointment to drop by the workshop or showroom if you’re planning to be in Florence, or view their catalogue online.
