Duncan Color Burst Crystal Chips Sloped Technique

The sloped design of these bowls help the crystals slide and produce dramatic and unpredictable results! Each one will be its own unique piece of art!

  1. For each of the pieces, follow the general instructions, altering each for the fired color and Color Burst Chips as listed.
  2. Wipe ware with damp sponge to remove bisque dust.
  3. Using either the Fan Glaze brush or the No. 6 Round as needed, apply two flowing coats of the designated glaze to the bowl, allowing the glaze to dry thoroughly between coats.
  4. Place an amount of the Color Burst Crystals on a plate or in a bowl, pour out a small amount of glaze onto the foam plate or foil and mix in an amount of the crystal chips. Using the No. 6 Round, load the glaze with crystals on the brush and apply to the lip and down the inside edge of the bowl, moving the crystals around for the desired placement. A heavier concentration of crystals will cause more color intensity and movement from the crystals, a lighter or more spaced amount of crystals will create a more dotted pattern of crystal bursts, and larger crystal chunks will create a larger color burst and flow, as a small crystal will create a tiny color spot. Let dry thoroughly.
  5. Stilt and fire to cone 06.
