Internal Glaze: Celadon B
C3 Celadon B/Jun's A+++++ Celadon (Cone 6 Reduction)
A Blue/Green Celadon, this glaze reacts strongly to the iron present in the clay body. White porcelains and stoneware with low iron content result in a strong blue. Higher iron porcelains produce a green or blue/green hue. For a nice bright blue, reduce iron to 1 percent. Pools in crevices and textured areas.

Without albany slip in the glaze, the rutile only turns blue/purple on a red clay body, streaking white in thicker areas. On a porcelain clay, it streaks titanium white. Runs and pools in crevices. Colour does not appear in reduction firing.
