Following manufacturer's instructions, create kiln wash using glass separator or kiln wash. Using a 1-inch brush, apply 3 - 4 layers of kiln wash to the mold, covering the entire depression. Allow the kiln wash to dry completely between layers and have the last layer be completely dry before using.
Pour frit into the depression in the mold, filling it to the top.
If the design has a "bump" in the mold for creating a hole in the fused design, be sure to leave the area clear.
Place the mold onto ceramic posts or a kiln shelf, inside the kiln. Set the controller for a full fusing.
The schedule used for the pieces shown is:
Ramp 1 - 900°F/hour to 1000°F. Hold for one minute.
Ramp 2 - FULL speed to 1480°F. Hold for 15 minutes.
Ramp 3 - FULL speed to 1100°F. No hold necessary.
Ramp 4 - 300°F/hour to 955°F. Hold for 15 minutes. Allow the kiln to cool to room temperature, or no higher than 100°F, before opening and removing the mold. Adjust the schedule based on your results.
