Botz Earthenware Glaze: Turquoise Crackle 9352

Size: 200ml brush-on liquid glaze.

Remove the glaze from the pot, stir and agitate the glaze in a larger container. Make sure all the material is mixed thoroughly. Whilst keeping the glaze moving, dip the brush and hold sideways, to keep the material evenly distributed, then apply using confident dabs, move the liquid around and work quickly and smoothly. 1 to 2 applications could be needed so allow to dry between coverings.

Stable between 1020°C to 1060°C (Cone 06 to Cone 04), but can be fired up to 1100ºC (Cone 03).

Apply sparingly, as it can run.

It can blister with an unsympathetic firing for some clay bodies.

Crazing develops after cooling in the kiln and this is reinforced in time, even up to a week after. If crazing does not develop, try removing wares from the kiln at approx 100 °C. Cracks can be highlighted with black China ink, acrylic paints or even strong black tea/coffee.

With a slightly thicker application the glaze pools on the inner surfaces of plates and bowls, making darker turquoise crackles.

Suitable for Raku.

Suitable for food bearing surfaces.
