clay
This word evokes a tactile sense of malleability and transformation. It suggests a material that is receptive to an external will, allowing a creator to impose a specific form upon a raw, earthy substance. This makes it a frequent symbol for human potential or the act of creation in art and mythology. In a practical sense, the term carries a heavy, dense connotation. Whether referring to the mud in a backyard or the medium in a studio, it implies a substance that clings, resists easy movement, and requires significant effort or heat to permanently change its state.
Uncountable when referring to the material as a bulk substance used for pottery. Countable when referring to specific types or deposits of different colored clays found in nature.
