Bricks dating back 5,000 to 7,000 years have been found in China’s Shaanzi Province, adding 1,000 to 2,000 years to China’s brick-making history.
“The five calcined bricks were unearthed from a site of the Yangshao Culture Period dating 5,000 to 7,000 years ago. Previously, the oldest known bricks in the country were more than 4,000 years old,” Shaanxi Provincial Institute of Archaeology researcher Yang Yachang said.
The bricks, including three red ones and two gray ones, all uncompleted, Yang said. The site under excavation is located at Liaoyuan Village of Baqiao District, and Huaxu Town, Lantian County of Xi’an, capital of Shaanxi Province.
Yangshao Culture is a Neolithic culture that flourished along the Yellow River, which runs across China from west to east. The culture was named after Yangshao, the name of the first village discovered of the culture, in 1921 in central China’s Henan Province.
Archaeologists used to believe the ceramics were applied to architecture in the Shang Dynasty (1600 B.C-1100 B.C.), which had been proved wrong by the new discovery, Yang said.
The smooth surface and rough surface of most well preserved red bricks are vertical to each other, and the rough surface was designed to be stuck to other materials, Yang said.
