This tea cup was created by artist Masashi Tsunokake. Masashi Tsunokake is based in Tokoname, Japan. He has been producing hand made goods since 1992.  His wares are fired in one of the six ancient kilns (Bizen, Echizen, Seto, Shigaraki, Tamba) in Japan.

The black tea cup is called “Tetsuyu” which uses a high porosity clay and a volcanic ash finish with a rough surface.

3 oz (100ml) capacity.
