Baked earth
Terra cotta is Italian for baked earth. It comes from the Latin terra cocta, cooked earth. The word names a kind of clay pottery fired at a fairly low heat, often around 1,000 degrees Celsius. During firing, iron oxides in the clay react with oxygen and turn it a reddish orange. That is the color this name stands for, even though real terracotta can also come out yellow, buff, pink or brown.
Pots, roofs and an army
People have shaped and fired this clay for thousands of years. The most famous example is the Terracotta Army of China's first emperor, Qin Shi Huang. Those thousands of clay soldiers were made more than 2,200 years ago.
