Why use Brazilian slate in the construction of billiard tables?
Slate is a metamorphic rock with very fine grains consisting mainly of quartz, white mica, chlorite, carbonate and iron oxide which are formed in low pressure and temperature. It was used in covering buildings because of its strength and durability. Thanks to the stability of its surface and its low moisture absorption, it is ideal for the design of pool tables. Slate is found in the U.S., Spain, Italy, China and Brazil.
