Astro Gems

Astro Gems

Astro Gems™ are an underglaze-based textural glaze that contains tiny crystals.

GENERAL USE

Stir and shake for 5-6 seconds before use – you’ll want to make sure the crystals are evenly dispersed in the glaze before applying. Apply 3 smooth, even coats to properly fired shelf cone 04 bisque using a soft brush, such as a CB-604 #4 Soft Fan Brush. Try to get the brush fully saturated (loaded) and apply alternate coats in a perpendicular direction to the previous coat (helps to evenly distribute the crystals on your surface). Fire to shelf cone 06.

AS-510 White Opal Astro Gem can be tinted using Mayco Underglazes. You may find success mixing stains – always conduct small tests before using on a wider scale. Mayco recommends using the darkest color of the Fundamentals Underglaze as the white will lighten.
