A beautiful, highly decorative glaze that creates a rich, volcanic texture in the firing. Works beautifully on high-fired stoneware and porcelain.
In comparison to the “white lava” this has more blue/grey hues as well as the surface is actually rough to touch (the white lava is silky to touch, so this one suitable for more decorative work).
Firing Range
1200–1260°C (≈ 2192–2300°F) For the look seen in my work, I recommend firing to 1260°C (≈ 2300°F).
This glaze is lead- and cadmium-free, however the highly textured surface is not recommended for functional food-contact areas unless used as a decorative edge, as seen in my pottery.
Sold in Powder Form Only
Mixing Guidelines
Important: You must mix the entire dry bag at once. Because the glaze is blended by hand, the ingredients are not uniform in small scoops. Mixing only part of the bag will produce uneven results.
Application
Apply a thick layer for the characteristic sculptural, cratered texture.
This lava glaze will create a volcanic surface on your piece. We recommend experimenting with:
• thickness of application • number of coats • firing cycles & temperatures
Always protect your kiln shelves well. As with all specialty glazes, testing is essential — results vary with application, temperature, clay body, and firing schedule.
• Do not ingest. • Wear gloves when mixing and applying. • Avoid glaze dust — never sweep dry material. • Clean spills or dried residue with a wet cloth only. • Keep away from eyes; if contact occurs, rinse thoroughly with water. • Ensure good ventilation during firing.
