View source for Nuka glazing

'''Nuka glazing''' is a ceramic glazing technique that uses ash derived from rice husks as a primary component of the glaze. The glaze typically produces soft, milky white surfaces with subtle variations in tone and texture.

The term ''nuka'' (Japanese: 糠) refers to rice bran or rice husks, which have historically been used as a source of ash in ceramic glaze preparation. When rice husks are burned, the resulting ash contains silica and other minerals that can form a glassy surface when fired at high temperatures.

In the preparation of nuka glazes, the ash is usually washed, sieved, and mixed with other materials before being applied to pottery. The glaze is often used on stoneware vessels and may produce creamy white, pale gray, or slightly translucent surfaces depending on the composition and firing conditions.

Nuka glazing has been widely used in Japanese ceramics and is particularly associated with [[Karatsu ware]]. The soft, natural appearance of the glaze is often appreciated in ceramics related to tea culture.

Variations in ash composition, clay body, and kiln atmosphere can produce subtle differences in the final surface, giving each piece individual character.
