Turquoise, transparent, glossy crackle glaze, must be applied in 1 coat only since it tends to run strongly. To prevent formation blisters, biscuit fire at 1000 °C. Some clays, in particular stoneware clays, are not suitable for this glaze even if biscuit fired at 1000 °C. 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 coffee.
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.
To achieve a coarser crackle: mix with 9342, e.g. 1 : 1
Firing range: 1020° – 1060° C
