Sunflower Seeds

Ai Weiwei's Sunflower Seeds is an artwork of staggering scale and meticulous craftsmanship. One hundred million individually handmade porcelain sunflower seeds carpeted 1,000 square metres of the Tate Modern's Turbine Hall to a depth of 10 centimetres, weighing a total of 150 tonnes. Each tiny seed underwent a 30-step process, hand-painted and fired at 1,300 degrees Celsius by over 1,600 artisans in Jingdezhen over two and a half years.
