Speedball : Mid-Fire Glaze : 473ml : Green Tourmaline

Speedball Mid-Fire Glazes have been developed in partnership with ceramic artist Nancy Sowder. They are available in a range of 30 colours for creating decorative mottled and reduction-like effects for pottery and ceramic works, as well as for sealing the clay body to make it waterproof and food-safe.

The Speedball Mid-Fire Glazes can be used on their own, or layered with other colours to create interesting variations. They can be applied by pouring, brushing, or dipping. Once dry, the work can be fired at Cone 5/6. Results may vary based on individual application methods and firing techniques. It is recommended to create a test piece as a visual reference. For consistent results, cool all colours on a normal cooling cycle.

Green Tourmaline is a gloss glaze that manifests a balance of yellows, blues, purples, and greens creating a harmonious surface packed with depth. Benefiting from a thicker application, Green Tourmaline will continuously play a complex tune around any surface. When fired to Cone 5 this glaze brings out dynamic purple and blue tones. A good stir before application will help maximise colour variations throughout the finish.
