Quick Answer: Is Clay Made From Dirt

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Shale, formed largely from clay, is the most common sedimentary rock.
