Underglazes come in three types:

  • Opaque, the mayco Fundamentals are nontoxic clay and water based opaque underglazes. These opaque colors are to be used when areas of solid-color coverage are desired.
  • Translucent the EZ Strokes. Think of the EZ's as water colors. Their translucent quality makes them suitable for use with a number of decorating techniques including airbrushing, antiquing and brushstrokes. 
  • Underglaze colors designed primarily for decorating bisque the Mayco Stroke n coats have a glossy sheen when fired. One, two, or three coats may be applied.
  • Astro Gems™ are an underglaze-based textural glaze that contains tiny crystals.

Use these glazes to create intricate, detailed designs and butt up to one another without colors moving. When used in a majolica process, Stroke & Coat® will not move nor blend with the colors beneath. Stroke & Coat® colors are intermixable, allowing artists to create custom shades. Thin with water or media to create a “wash” or watercolor style of design. Because the liquid color is consistent with the fired color, artists will have no trouble visualizing finished results as they create.

  • 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.
