Tips

Tips for Sparkle Black Engobe

  • To enhance the sparkle and improve texture, use your fingers to burnish/polish the surface of the ware before the last layer is dry. Polishing is not needed when used in combination.
  • Can be applied to wet clay, greenware or soft fired, cone 04 bisque.
  • Engobes are often used for a variety of decorative techniques, such as sgraffito and majolica.
  • Fires matte. Apply clear glaze (SW004) Zinc-Free Clear to intensify color or for use on dinnerware.
  • SW004 Zinc-Free Clear is recommended for a black finish. SW001 Stoneware Clear will change the color to a rich brown and affect the sparkle.
  • Engobes will impact glaze results when used as a base. Engobes are used to change the color of your clay color surface without cross contamination and easy clean up in your studio.
  • Can be used in oxidation or reduction firings. Results may vary.
  • The choice of clay body, thickness of application, firing process, and temperature will greatly affect the fired results. Always test your application on your clay body in your kiln environment.

Tips

Tips for Black Timber

  • Upon opening, crystals will be concentrated in the bottom of the bottle. Stir/shake thoroughly to incorporate before each use.
  • Crystals can create movement. Avoid having a heavy concentration of crystals near the bottom of your piece.
  • When storing a crystal glaze, you may consider storing upside down to make crystal more accessible.
  • Can be used in oxidation or reduction firings. Results may vary.
  • The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results. Always test in your kiln, on your clay body

Tips

Tips for Mint Speck

  • Mint Speck uses SW135 Wintergreen as the base glaze.
  • We recommend firing our matte glazes to cone 6 to produce a satin matte finish.
  • Upon opening, specks will be concentrated in the bottom of the bottle. Stir/shake thoroughly to incorporate before each use.
  • Can be used in oxidation or reduction firings. Results may vary.
  • The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results. Always test in your kiln, on your clay body.

Tips

Tips for Green Jasper

  • Green Jasper uses SW250 White Opal as the base glaze.
  • Upon opening, crystals will be concentrated in the bottom of the bottle. Stir/shake thoroughly to incorporate before each use.
  • Crystals can create movement. Avoid having a heavy concentration of crystals near the bottom of your piece.
  • When storing a crystal glaze, you may consider storing upside down to make crystal more accessible.
  • Can be used in oxidation or reduction firings. Results may vary.
  • The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results. Always test in your kiln, on your clay body.

Tips

Tips for Sage Gloss

  • Can be mixed with other Stoneware Gloss glazes (SW500 series) to produce additional stable and opaque colors.
  • Layer design work with other Stoneware Gloss series colors to create crisp images that won’t blur or require clear glaze.
  • The choice of clay body, thickness of application, firing process, and temperature will greatly affect the fired results. Always test your application on your clay body and in your kiln environment.
