Terracotta is a type of clay that is often used to create pottery, sculptures, and building materials. It is known for its reddish-brown color, which comes from the iron content in the clay. Terracotta can be easily molded when wet and hardens when fired in a kiln, making it a popular choice for artists and craftsmen. In addition to art, terracotta has historical significance, especially in ancient cultures. For example, the famous Terracotta Army in China consists of thousands of life-sized figures made from terracotta, created to accompany the first emperor, Qin Shi Huang, in the afterlife.
