Terracotta is a type of clay that is fired at a low temperature, resulting in a durable and porous material. It is often used for pottery, sculptures, and building materials. The reddish-brown color of terracotta comes from the iron content in the clay, which gives it a warm, earthy appearance. This versatile material has been used for thousands of years in various cultures around the world. Notable examples include the Terracotta Army in China and Mediterranean pottery. Terracotta can also be found in roof tiles, flower pots, and decorative items, making it a popular choice for both functional and artistic purposes.
