In people's eyes, ancient terrazzo is always labeled as "dirt ugly".
It is a product that mixes gravel, glass, quartz and other materials with cement binder, and then grinds and polishes.
In my memory, terrazzo is mostly used in schools, hospitals and other large buildings. Although it is convenient for construction, low cost and wear-resistant, it always gives people a very low feeling.
Since the 1990s, terrazzo has gradually withdrawn from the historical stage and been replaced by other more advantageous new materials, which has been silent for a long time.
