low fire clay molds

[Georgeann]

Your firing schedule is excessively conservative. I have made many molds from low fire clay and my schedule regardless of thickness follows….

Dry 1-2 weeks with plastic over (prevents cracking)

Dry on top of kiln overnight (during the firing of other items)

To cure or complete the mold my kiln firing is………

300 -1000 hold 30min

500-1500 hold 5min

off (let cool basically overnight)

then wash with kiln wash like any other mold.

Never had a problem and still use every mold I have made.
