Tate Modern conservator maintains Ai Weiwei's Sunflower Seeds installation in 2010

In 2010, a conservator at Tate Modern performed maintenance on Ai Weiwei's Sunflower Seeds installation in the Turbine Hall. The work consisted of millions of hand-painted porcelain seeds covering the floor. Paul Grover photographed the conservation activity for the Daily Telegraph. Artcritical published the image on December 23, 2011, as part of their online content. The installation was a major commission for the museum's Unilever Series. Ai Weiwei created the piece to explore mass production and individuality in contemporary China. Each porcelain seed was individually crafted by artisans in Jingdezhen. The Turbine Hall at Tate Modern hosted the installation from October 2010 to May 2011.
