Twilight Sky ^6Twilight Sky is a complex inky blue glaze reminiscent of the night sky. Small silver crystals float on a variegated blue green glossy background punctuated by islands of light blue crystals that are holographic in the right lighting. Looks great on all our cone 6 clays, though will have the most vibrancy on light clays. On Brown Bear, it takes on an almost metallic matte finish that could be especially nice as a sculptural surface or a contrast glaze
