Clay
(i) A soil separate consisting of particles <0. 002 mm in equivalent diameter. See also soil separates. (ii) A textural class. See also soil texture. (iii) (In reference to clay mineralogy) A naturally occurring material composed primarily of fine-grained minerals, which is generally plastic at appropriate water contents and will harden when dried or fired. Although clay usually contains phyllosilicates, it may contain other materials that impart plasticity and harden when dried or fired. Associated phases in clay may include materials that do not impart plasticity and organic matter.
