Physical properties

Hardness varies (6-7 for quartz/granite chips, 3-4 for marble); Multi-colored clasts; Dull to polished luster; Heterogeneous texture with visible aggregate and binder.

Formation & geological history

Modern man-made material created by mixing marble, quartz, granite, or glass chips into a cementitious or polymeric binder. Originates from 15th-century Venetian construction techniques.

Uses & applications

Used primarily for flooring, wall cladding, and countertops in residential and commercial architecture due to durability and aesthetics.

Geological facts

Terrazzo was originally invented by Venetian mosaic workers as a way to use up scrap marble chips from high-end projects. It is considered one of the earliest forms of sustainable construction recycling.

Field identification & locations

Identify by the presence of angular rock fragments embedded in a solid matrix (often concrete). Often found in government buildings, schools, and mid-century modern homes.
