First Firing of the Kiln
The purpose of the first firing is to put a protective oxide layer on the elements and thermocouple.
The first firing is done without ware in the kiln that might give off fumes that contaminate the elements.
This first firing should have shelves and witness cones. The witness cones should be on the middle of the
shelf nearest the center of the kiln. The programmed cone number should match the cones provided with
the kiln. Our example calls for a cone 04 firing but if your kiln is supplied with different cones, substitute
that cone number in the programming.
The first firing should be done according to the kiln manufacture’s specifications if they are different from
these instructions.
