Add AMACO® Gum Solution to glazes to improve their brushability and slow their drying time which results in a more even and consistent application. Old, thick glazes can be brought back to their original creamy consistency by thinning the glaze with water first, then adding about a tablespoon of AMACO® Gum Solution, or as much as needed to obtain good brushability without drag. AMACO® Gum Solution will prevent glazes from drying fast and cracking. After using AMACO® Underglaze Pencils and Crayons, carefully spray or brush a diluted coat of Gum Solution all over the surface to seal the underglaze. Let it dry, then brush on a clear glaze. The Gum Solution seal will prevent the colors from smearing while brushing on the glaze.
