|From Italian terrazzo "terrace, balcony"
a faux-marble flooring or countertopping material, made up of small
chips of stone that are set hard in a binding material and then ground
over until completely level.
Marble-chip, cementitious terrazzo requires three layers of materials.
Terrazzo was originally invented by Venetian construction workers as a low cost flooring material using marble chips from upscale jobs. The workers would usually set them in clay to surface the patios around their living quarters. Consisting originally of marble chips, clay, and goat milk (as the sealer), production of terrazzo became much easier after the 1920s and the introduction of electric industrial grinders and other power equipment.
Today, most of the terrazzo installed is epoxy terrazzo

chips of marble, glass or other aggregates embedded in tinted cement,
ground smooth and polished to a silky sheen - may have been yet another
of mankind's accidental discoveries. In the 15th century, mosaic
artisans in northen Italy swept waste marble chips out onto their
terraces, terrazzi, and smoothed the surface simply by walking over it.
When workers learned to press the chips into a more permanent clay
base, then grind and polish them with heavy stones, terrazzo caught on.
Michelangelo used it in St. Peter's Basilica.
