Cone 06-05. Crackle glazes are formulated to produce a network of cracks on fired ware similar to crazing, giving it an old or antique look. These glazes can be used for an all over coverage or they can be applied over an underglaze. Because of the transparency of the crackle glazes, the underglaze design will show through.

To emphasize the crackle after firing, swab the lines with colored inks. Crackle glazes are recommended for decorative items only, as these glazes do not seal the surface of the ware as other glazes do. Apply three crosshatched coats of Crackle glazes over a mature Cone 04 (1971 degrees F, 1077 degrees C) bisque.
