Akitsu Mumyoi Oxidation Firing: Tea Cups
Tea cups and free cups in Akitsu Mumyoi Oxidation Firing.
A cup is the last surface the tea touches before it reaches your mouth, so it affects the taste as well. Matching it to your teapot's clay lets the effects of the clay add up.
The clay is described on the Akitsu Mumyoi page, and the firing on the Akitsu Mumyoi Oxidation Firing page.
