Orange Lustre, 1/2 oz. Lusters have a thin reflective surface that creates a prism of color. Lusters give a wide variety of effects and the final colors and tones are somewhat unpredictable, affected by the firing temperature, oxygen environment in the kiln, and the other pieces firing in the same kiln. For best results, use a clean dedicated brush, allow to completely dry and then fire at 019-018, making sure you fire in a kiln rich with fresh air. Lusters can be applied over painted surfaces and can be painted over after application. After firing, a brilliant alluring color results, often changing with the viewing angle. Can be thinned with Luster Essence if necessary. California residents see Prop 65 Warnings
