Cork Clay 8 oz
Use as an armature for beads and other hollow objects. Burns out completely during firing. Non-toxic, safe for indoor firing. 8 oz package.
To burn out cork clay, use a 2 segment program. Segment 1: fast ramp to 800F, hold for 20 minutes. Segment 2: fast ramp to target temperature, hold for desired time.
This schedule allows the hot burning cork to incinerate before moving to sintering temperatures.
