Yuppers- it's interesting that in the kiln you can directly see the effect of burning wet wood. At certain points I put it in there on purpose because the water creates a reducing atmosphere which is good for certain glazes. The kiln is very responsive, and in less than a minute the temp change is visible on a pyrometer I stuck through the roof. The kiln will be in a steadyish climb- throw in fresh wood- it may stop or fall a bit.
