Made with scarce red iron oxide which was produced from natural minerals. The kiln managed to get enough of this ingredient when it was found by chance during the demolition of an old warehouse. The red iron oxide was ground for 1000 days to get this beautiful color.

Due to the property of the clay, there maybe 1 - 2 pinholes on the surface.

Comes in a paper box.
Handcrafted in Gifu-pref., Japan at Zohogama kiln
