So what do the Japanese potters put on their wood fire pots? At least part of the firing is in oxidation.


A part of any natural fuel kiln firing is in oxidation, even wood. A natural fuel firing may include a body reduction phases (typically early on, around cone 12 to 10 and a glaze reduction phase (typically at near the end of the firing). At the end of the firing, you close off the fuel ports and the damper . . . basically, preventing air to enter the kiln while it cools. At least that is my understanding.

They use red iron oxide, other oxides, etc. The challenge is finding glazes that work with the oxides. Red iron oxide, in addition to being a colorant, is also a flux that can cause an otherwise stiff, non-moving glaze to become runny. It is how the red iron oxide interacts with the glaze ingredients.

I've tried several of the Van Gilder recipes . . . including cream rust;  mostly use it as a liner.  Some of his glazes are from Mastering Cone 6 glazes (black/licorice).
