Application:
- Apply 3 even, solid coats to properly
fired shelf cone 04 bisque using any soft fan or oval mop glaze
brush. Fire to shelf cone 06. To accentuate the crackle pattern,
antique the fired piece with a non-fired acrylic stain or mineral
spirit stain.
- Simply apply a coat of the desired
color to the fired piece and wipe off with a soft cloth. The color
will fill in the cracks and make the crackle pattern stand out.
Firing: Fire to shelf cone 06,
allowing pieces ample room in the kiln for air circulation during
firing. These glazes can also be high fired up to shelf cone 6 with
various color shifts.
Notes:
- Sometimes the crackle pattern will
develop when the kiln is cool enough to open. Other pieces may need
to sit out of the kiln for a period of time before the crackle
pattern develops.
- Remove pieces from the kiln with a
coffee filter or clean rag placed over your hand. The oils on the
skin can fill the cracks and prevent the antiquing colors from doing
so.
- Classic Crackles are non-toxic but are
not recommended for food surfaces. Bacteria could become trapped in
the exposed bisque between the cracks, making it unsanitary.
- Crackle glazes place stress on the ware
during firing. To prevent containers from splitting or cracking
apart, make sure to use a non-toxic glaze to coat the remainder of
the inside of the piece (such as Series 2000) to further reduce
stress.
- Use Stroke & Coats or One Strokes
to create designs under Crackles. Create the design on fired 04
bisque, using only 1-2 coats or the crackle will not properly
develop. Allow to dry and apply 3 coats of Crackles. Allow to dry
and fire to cone 06.
- When using One Strokes, apply design on
greenware and fire to 04. Then apply 3 coats of Crackles, allow to
dry and fire to cone 06.
