Layered Green Crystalline Glaze with Warm Clay Break-Throughs
Green Calcite Studio Line Crystalline Glaze develops layered pale blue-green to grey-green crystal formations around warm areas of exposed clay. The fired sample shows overlapping crystalline growth with darker centres and edging in places, creating an organic mineral appearance where cool green tones contrast clearly with the warmer clay beneath.
Choose Green Calcite when you want both crystalline growth and clay break-throughs to contribute to the finished surface rather than producing a uniform glaze colour. Crystal size, colour and distribution can change with glaze thickness, clay body and firing conditions, so use the fired sample as a guide and test your application and firing schedule before using the glaze on important work.
- Known to flow during firing, so keep heavier application away from the base and allow for glaze movement.
- A standard Cone 6 firing at around 1220°C can develop crystal formations with a soak.
- Extended or stepped cooling can encourage larger or more complex crystal growth.
