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.
