Clay is a fine-grained natural sediment that is formed from the weathering of rocks and minerals. It is composed of hydrated aluminum silicates, and it is plastic when wet and hardens when fired. Clay has been used for pottery for thousands of years, and it is still one of the most popular materials for making pottery today.
