Kiwi underglaze offers flexibilty to be applied in a number of ways, including:

• Application on to bisqueware, followed by a coat of clear glaze, then glaze fired.
• Application to greenware and then bisque fired at cone 06 (1000°C / 1800°F) prior to an application of clear glaze.
• Application to bisqueware followed by a second optional bisque firing at cone 06 (1000°C / 1800°F) to "harden on" the colour prior to glazing.

After firing, the colour intensifies and becomes glossy. When left unglazed and fired to around cone 06 (1000°C / 1800°F) or more, the colours assume a velvet matte appearance. This is a good surface for sculptural forms and as a decorating effect where glazing is not essential.

Colour should be applied as thinly as possible, in layers, to achieve the desired effect. If water has been lost a little more may be added but be careful not to dilute colour power. Application gives a translucent effect with 1 coat, semi opaque with 2 coats and opaque with 3 coats. Colour is brightest when clear glazed and fired to cone 4 or 5 (approximately 1180°C / 2150°F), but full glaze firing range is cone 04 to cone 9 (approximately 1050-1260°C / 1920-2300°F).

Safety: toxic material or hazardous as airborne dust, and/or as powder and/or in liquid suspension. Work will be foodsafe after glazing and firing.

Working Notes

• Mix your underglaze thoroughly before using it. Underglazes can settle over time, so it's important to mix them well to ensure consistent results.
• Use a clean brush or sponge to apply the underglaze. Contamination from previous colours or particles can affect the final outcome.
• Apply the underglaze in thin layers to avoid cracking or flaking. Thick layers are more prone to these issues.
• Allow the underglaze to dry completely before applying additional layers or a clear glaze.
• Use underglazes to create detailed designs and patterns. They are especially useful for fine details that are difficult to achieve with regular glazes.
• Use masking tape or wax resist to create sharp lines and edges.
• Experiment with different techniques, such as sgraffito (scratching away layers of underglaze) or stamping to create unique designs.
• Use stencils or stamps to create consistent patterns. Create gradients by blending different shades of underglaze.
• Keep in mind that underglazes will appear different after firing, so always do test firings before starting a large project.
• Use a clear glaze over underglaze to protect the design and make it more vibrant.
• Apply the clear glaze in thin layers to avoid cloudiness or bubbles.
• Be careful not to overfire the underglaze, as this can cause it to lose its colour.
• Mix underglazes with water to create a watercolour effect.
• Use a spray bottle to apply underglaze for a misty, atmospheric effect.
• Most importantly, have fun and experiment with different techniques and designs!
