Brick

= = __BRICK__

 A brick is a block of ceramic material. The oldest discovered bricks, originally made from shaped mud and dating to before 7500 B.C. for building may be made from clay, Sahle, soft slate, calcium silicate, concrete, or shaped from quarried stone. However, true bricks are ceramic, and therefore created by the action of heat and cooling.

**__USE__** Bricks are used for building and pavament. In the USA, brick pavement was found incapable of withstanding heavy traffic, but it is coming back into use as a method of traffic calming or as a decorative surface in pedestrian precincts. Colombian architect Rogelio Salmona was noted for his extensive use of red brick in his buildings and for using natural shapes like spirals, radial geometry and curves in his designs. Most buildings in Colombia are made of brick, given the abundance of clay in equatorial countries like this one.
