Cortesia de Endicott
Composed of very fine mineral particles and formed through the weathering and erosion of rocks over long periods of time, clay has properties that make it useful for a wide range of applications. When wet, it becomes extremely malleable and plastic, and can be molded into different shapes. When dry, it is hard and rigid, and is widely used for construction and ceramics. Clay pavers are quite common for outdoor use due to their durability, resistance to weather and traffic, their natural hues and ease of installation.
