AMACO CTL 49 Azurite
AMACO Crystaltex Glazes consist of a base glaze color with the addition of one or more complementary crystals. The crystals create bursts of color which contrast and blend with the base glaze, resulting in a spontaneous range of color. Multi-color effects can be subtle or bold. For application by dipping or pouring, thorough stirring of the glaze is necessary since the crystals settle to the bottom of the jar. A more controlled decorative effect can be obtained by brushing. Dip the brush in the glaze at the top of the jar and apply two or more coats. Lift the crystals from the bottom of the jar with the brush and place where desired.
Crystals fan out on flat horizontal surfaces and run on vertical pieces. To spray the Crystaltex glazes, spray a good coat of glaze without the crystals, place the crystals by hand where you want them, then spray another thin coat over that. Best results are obtained at Cone 05 (1911°F, 1044°C). CTL-3, CTL-31, and CTL-41 have a matte finish with glossy crystals when fired. The rest of the series is either glossy or a textured gloss/matte finish. All crystals fire to a gloss finish.
