The Sahara glazes are available in pints and gallons (liquid), 1 lb. dry or a 25 lb. dry dipping glaze formula (3 colors) packaged in a 5 gallon bucket for easy mixing.

AMACO Sahara High Fire Glazes work well and produce interesting effects when fired in reduction as well as in oxidation (reduction firing not recommended for HF-26). We also suggest experimentation using Amaco Opalescent glazes or High Fire Texturizers in combination with High Fire Glazes.

In liquid form, AMACO Sahara High Fire Glazes are ready-to-use while dry powdered glazes are mixed with water. Although these glazes may be applied on bone dry greenware for single firing, it is easier to apply them on low fire bisque. HF-26 and HF-32 should be applied thicker than other glazes in this series. HF-36 should be fired to Cone 4 (2161°F, 1183°C) to obtain texture. For best results: if brushed they will need three coats. Then clay and glaze may be matured at the same time, at the recommended firing temperature of Cone 5 (2205°F, 1207°C).

A zinc-free, clear, transparent high fire glaze (HF-9) is also available. Because the presence of zinc in a glaze formula may change the appearance of certain colors (green, black, gray, etc.), a zinc-free clear is very important for application over underglaze decoration. When used under HF-9 Zinc-Free Clear, colors will fire true. Any variation in color intensity of the underglazes will then depend on the individual color stability at Cone 5. Firing range is from Cone 4 (2161°F, 1183°C) to Cone 6 (2269°F, 1243°C).
