Botz Ceramic Glaze Turquoise Crackle 200ml. Turquoise, transparent, glossy crackle glaze, must be applied in one coat only since it tends to run strongly.  To prevent formation blisters, biscuit fire at 1000°C.  Can show blisters on some sorts of clay when applied on both sides/all around.

Crackles develop mostly after cooling in the kiln and this is reinforced in time, partially up to 1 week.  If crackles did not develop, the glaze can also be removed from the kiln at approx. 100 °C and quenched with cold water.  The crackle net is inked, e.g. with black China ink, multi-coloured acrylic paints, strong black tea or else.  With a slightly thicker coat on horizontal surfaces such as the inner surface of plates and bowls, interesting, darker turquoise scale crackles stars to form on some clays.

Consistent in firing range 1020°-1060° and forms cracks. Raku suitable and semi-transparent.
