Banko Yaki : Tea Cups
Tea cups and free cups in Banko ware.
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 and firing are described on the Banko Clay Reduction by Masaki Tachi page.
