Cone 6: Galaxy is a semi-transparent charcoal colored gloss glaze that contains a three-tone white, orange, and blue crystal. As the crystal melts, a brilliant bloom of white, orange, and blue appears. The glaze is reminiscent of a star being born. Cone 10: Crystals and base showcase more blue hues. Crystals melt. TIP: SW-209 Charcoal is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-209 Charcoal with a third coat of SW-156 Galaxy.
