Sahara Glazes
Cone
5. Sahara Glazes are compounded to match porcelain and
stoneware bodies. Matt and textured glazes suitable for
stoneware and transparent gloss glazes for translucent
porcelain are included in this series.
Sahara Glazes work well and produce interesting effects
when fired in reduction as well as in oxidation
(reduction firing not recommended for HF-26).
Sahara High Fire Glazes are ready-to-use. 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).
