A better clay surface is made up not just of clay, but of a mixture of clay, sand, and silt; the mixture can be screened and blended to optimize its performance. When first introduced, this clay/sand/silt mixture represented a vast improvement over the older solid clay surface used on playing fields and tracks, although it still tends to form ruts and can become slick when wet. This mixture is the most popular clay topping in use today.
