A mottled mid green, grainy, paler where it thins.

$36

Suggested retail price. In-store prices and availability may vary by location.

Spectrum's 900 series is a low fire glaze with the look of stoneware, and the colours can be layered over one another for more effects. The surface is satin, and it breaks to some degree. Three coats on white bisque give the full colour. Spectrum rates the series cone 06 to 04, 1015 to 1060°C, with cone 05 the recommended firing. Do not use it on the same piece as a 700 series glaze, because the two expand at different rates and the combination can crack. Lead-free. Spectrum does not rate it non-toxic in the liquid state.
