Duncan Crystal Glazes

    Duncan Crystal Glazes are nontoxic gloss glazes that contain glaze crystals that melt and flow during the firing. Each of the Crystal Glazes are different, some glazes contain crystals of just one color, while others contain several different colored crystals. While these glazes are nontoxic and suitable for the classroom, the glazes should never be considered dinnerware safe as crazing may develop due to the presence of the glaze crystal.  Available in 42 total colors split into several groups including the Original Crystal Glazes and the Earth and Sky Crystal Glaze Series.

    All Duncan Crystal Glazes are available in 4 oz sample sizes and most are available in 16 oz (pint) bottles. Dogwood Ceramic Supply stocks all available sizes and colors.

Crystals™ Glazes

Duncan Glaze Crystals 

Crystals™ Glazes

    Duncan Crystal™ Glazes consist of a base glaze, that usually matches an Envision™ Glaze in color, with various colored crystals added.  When fired these crystals produce unique results every time.  As shown on the vase above, Crystal Glazes can move during the firing.  The amount of movement depends upon the size of the individual crystal, the slope of the piece, as well as the firing temperature.

    All Duncan Crystal™ Glazes are rated nontoxic, however only CR 905 Blueberries is considered dinnerware safe. The other Crystal™ Glazes are not considered dinnerware safe as the crystals in the glaze may cause crazing (fine spider-web cracks in the glaze surface), which also means that Crystal™ Glazes are not recommended for the interior of a vessel that may contain water.  On the interior of a vase it is recommended that the matching or complimentary Envision™ Glaze is used to maintain waterproof food safety.

    Crystal™ Glazes are a very versatile decorative glaze.  Duncan Crystal™ Glazes may be used in conjunction with other Crystal™ Glazes, or in combination with satin or other gloss glazes.

Basic Instructions:

1. Stir product thoroughly to suspend the crystals that may have settled at the bottom of the jar.  Note: Mixing instructions depend upon the crystal size, refer to the jar label for complete instructions.

2. Apply 3 flowing coats to shelf cone 04 bisque.  Keep larger crystals sparse on the sides near the bottom of the piece to prevent the crystals from flowing off the piece and onto the kiln furniture.  Keep all crystals off the bottom of the ware, or edges of boxes to prevent an uneven bottom.

3. Stilt and fire to shelf cone 06.  Allow slightly more space between pieces in the kiln as some bubbling of the crystals may occur during the firing.

Project Hints:

    Duncan's Crystal Glazes are wonderful for children and classroom.  Adults may desire to move beyond the color choices made by Duncan and experiment with Spectrum's Glaze Crystals to achieve a virtually unlimited color combinations.
