The first emperor of China, Qin Shihuang, completed a huge number of projects during his rule. Between 221 and 210 B.C., he started the building of the Great Wall. The emperor also ordered the building of a huge army of life-sized terracotta soldiers. These, he hoped, would protect his tomb (坟墓) after his death.

Lost in Time

The soldiers in Xi’an’s terracotta museum are today light brown, but they weren’t always. They began as an army of red, blue, yellow, green, white and purple. Sadly, most of the colors did not last to the present day. After being exposed (暴露) to air during digging, the coating under the paint began to fall off. The paint disappeared in a short time, taking away the important pieces of history.

New Technology

Now new technology is starting to show the army’s true colors. Archaeologists (考古学家) have recently discovered an area with more than a hundred soldiers. Many of these still have their painted features (特色), including black hair, pink faces and black or brown eyes. Chinese and German researchers have developed a chemical liquid (液体) to help save the soldiers’ colors. After finding a soldier or another art piece, archaeologists put the liquid on it. They then cover it in plastic.

Back to Life

Archaeologists are also finding colors in the dirt (涂层) around the soldiers. It’s important not to do anything with the dirt, so the colors won’t be lost. “We are treating the dirt as an art piece,” says Rong Bo, the museum’s leader. “The next challenge,” says Rong Bo, “is to find a way to use the colors onto the army again. Once that happens, artists can bring Emperor Qin’s army back to its full, bright colors.”
