Nuka is the Japanese term for rice bran and more importantly for my clay interests Nuka also refers to a creamy milky white glaze traditionally made with ash from rice bran. While a student at Clemson University, I saw work that had been glazed with a Nuka glaze. I really liked the look of the glaze. This is not a glaze that I formulated, but one I found after looking through old magazines and searching online. This glaze isn’t made with rice bran ash and has been formulated with the raw materials that you can get at a ceramic supply store.
Recipe for the Nuka glaze by weight:
Custer Feldspar 73.0%
Wood Ash 8.0%
Nephelene syenite 10.0%
Tin Oxide 1.0%
