This is for a Cone-Art 2818D kiln with an exhaust fan on at start of firing.

Use this for the best possible results for transparent glazes and glossy glazes where you do not want any crystallization.

If the kiln is full, lengthen the first step hold time to drive out all residual or remaining water from body and glaze (depending on the ventilation in your kiln). This schedule assumes that a good bisque has been done.

If Cone 6 has fallen too much drop the temperature for ramps 2 & 3 10 degrees F.

If cone 6 still does not completely fall (e.g. you fire heavy loads), increase the hold time in Step 3 by 5 minute increments.
