Crystaltex glazes produce exciting, unpredictable multicolor effects. Ready-to-use, liquid glazes feature one basic color mottled with a variety of contrasting colors. Crystals create bursts of color which contrast and blend with the base glaze, resulting in a spontaneous range of color. Controlled effects can be achieved by brushing or placing crystals where desired. Crystals fan out on horizontal surfaces and run on vertical surfaces. Fire to Cone 06-05; best results are obtained when fired to Cone 05. Must be applied on mature Cone 04 bisque. Contains no lead or cadmium. Melon is food safe when fired to recommended temperatures. Pint jar. AP Seal, non-toxic.
