Asuka Toba's Lidded Single-Handed Donabe (Retail Price: ¥22,000 + tax) Used to cook rice about twice. This one contains petalite. It doesn't leak, and compared to those without petalite, the bottom of the pot turns black more evenly. The handle wrapping is originally glued to the handle, so you don't have to worry about it unraveling when washing. There is discoloration on the bottom of the pot that occurs when heated, and the characteristic crazing of earthenware. However, there are no cracks on the outside of the pot's bottom. *Considering the above, please consider this item only if you understand the artist's unique style and are familiar with Toba-san's heat-resistant ware.
