    To put your kiln in reduction: Generally, start the reduction cycle when the witness cone before your target cone begins to tip. For example, with a cone pack with cones four, five, and six (the target cone being cone five), you will want to start reduction when cone 4 starts to tip. You want to build up some pressure in the kiln.

    Manganese is usually introduced into glazes as manganese carbonate. Black manganese dioxide is more often used in slips and clay bodies, where its coarseness yields spots and splotches. Manganese, when compared to cobalt or copper, is a fairly weak colorant. It is toxic; handle with caution, using all safety precautions.
