I have recently done a little study of the high fire clay bodies from Continental Clay in Minneapolis. I made teabowls out of each of the clay bodies, and fired one in c. 10 reduction and one in soda (also c. 10 reduction). They are both glazed in a luster shino glaze which shows off the differences in the clay bodies beautifully. The c. 10 pots are glazed both inside and out with the shino glaze (left). The soda pots are glazed on the inside, and on the rim (right). There are 9 clays that I tested in total- so keep scrolling down… Enjoy!
