Northstar Irrid is the least saturated of the transparent striking colors. When oxidized, it produces a silvery transparent metallic blue. When reduced, Northstar Irrid turns a light sea green color. Irrid can be worked hot and is another forgiving striking color. Try layering it over an opaque to yield new effects.
CAUTION: AVOID EXPOSURE TO GLASS DUST. ALWAYS USE A DUST MASK AND EXHAUST HOOD WHEN HANDLING FRIT AND POWDERS.
