The Hilda Hellström dishes may not be safe to use, but they are definitely a powerful narrative of the unfortunate events that befell Japan last year.
Hellström journeyed to Fukushima into the nuclear disaster site to visit the last person known to be living there, Naoto Matsumura. Turned away by extended family home away from the site, Matsumura stayed to take care of his animals. Together they took soil three inches under the surface of his rice farm. The radiation read as 2,500 becquerel/kilogram, which is safe enough to be around. Back in the U.K., she moulded them into rough plates, bowls and vases, which she states she probably wouldn't eat from.
As more of an art collection than meant to serve their function, these pieces would make great dinner conversation.
