(2010) Opening in October 2010 at the Tate Museum in London, Ai displayed 100 million handmade and painted porcelain sunflower seeds. The work as installed was called "1-125,000,000" and subsequent installations have been titled "Sunflower Seeds". The initial installation had the seeds spread across the floor of the Turbine Hall in a thin 10 cm layer. The seeds weigh about 10 metric tonnes and were made by artisans over two and a half years by 1,600 Jingdezhen artisans in a city where porcelain had been made for Chinese rulers and court for over one thousand years. Made by the traditional method for which the city is known, a thirty-stage process was employed. The sculpture refers to chairman Mao's rule and the Chinese Communist Party. The mass of tiny seeds represents that, together, the people of China can stand up and overthrow the Chinese Communist Party. The seeds also refer to China's current mass automated production based on Western style the consumerist culture. The sculpture challenges the "Made in China" mantra, memorialising labour-intensive traditional methods of craft objects.
