Kometatsukun (2005)

Kometatsukun are thorium-containing ceramic disks that were developed by Yoshimasa Watanabe, President of Only-One Co. Ltd. of Japan. They are said to have numerous applications. For example, not only do they kill bacteria and eliminate water odors, they also improve the taste of rice, sake, wine, green tea.  When brewing tea, the water should be boiled with a disk immersed in it before being poured into the teapot. When preparing rice, the disk can simply be placed on top as the rice is cooked.
