Chinese artist Ai Weiwei's "sunflower seeds" - a work made up of 10 tonnes of porcelain seed replicas - has been bought by Tate Modern.
The London gallery has acquired around eight million of the 100 million porcelain reproductions.
They make up just under one tenth of the original work, commissioned for the Tate's 2010's Unilever Series.
It saw 100 million seeds spread over the floor of the gallery's vast Turbine Hall.
Shortly afterwards it was cordoned off over health and safety fears because of ceramic dust. The gallery initially had plans for visitors to be able to walk on the seeds.
The work was on display at Tate Modern from June 2011 to February 2012.
Each porcelain seed had been individually handcrafted by skilled artisans in the city of Jingdezhen, which is famed for its production of Chinese Imperial porcelain.
The work has been purchased for an undisclosed figure with assistance from the Tate International Council, the Art Fund, and private donations.
It's thought the remaining seeds will go back to the artist.
