A highly decorative and sculptural glaze that creates a rich, volcanic texture during firing.
Designed for high-fired stoneware and porcelain, this glaze develops a dynamic, cratered surface full of movement and depth. For an especially pronounced effect, apply the glaze 3–4 times thicker than a normal glaze application. The thicker layer encourages more bubbles and creates the characteristic volcanic surface.
The glaze is best applied as a thick, creamy consistency that can also be dabbed on with a brush, rather than brushed on as a conventional thin glaze.
Pictured on porcelain, where it is shown alongside FROSTY Green, and on black stoneware layered with IVORY. The tile shows the glaze over white stoneware.
1200–1280°C (Cone 6–9)
Pictured samples are fired to 1260°C (Cone 8, ≈ 2300°F).
At around 1260°C, the surface becomes beautifully balanced: the bubbles soften and melt just enough to create a smooth, almost silky texture without sharpness.
At the lower range (1230–1250°C / ≈2250–2280°F), the result is drier and more textured.
Fired beyond 1270°C (≈2320°F), the glaze becomes more fluid and the bubbles may melt further.
See my online courses for detailed firing and application guidance.
This glaze is lead- and cadmium-free. However, because of its highly textured surface, it is not recommended for functional food-contact areas. We recommend using it as a decorative glaze or on non-food-contact surfaces.
IMPORTANT:
You MUST mix the entire dry bag at once.
Because this glaze is blended by hand, the ingredients are not uniform in small scoops. Mixing only part of the bag can produce uneven results.
For this glaze, use approximately 0.7:1 water-to-powder ratio to achieve a thick, creamy consistency suitable for dabbing or building up the surface.
100 g powder → 70 ml water
500 g powder → 350 ml water
2500 g powder → 1750 ml water
Mix thoroughly and sieve once before use.
