Kiln-opening this morning
Donna Sutherland and I emptied the kiln this morning. This was a pretty good firing, given that it was mostly a clean-the-bisque-off-the-shelves load. And given that when I shut down yesterday afternoon, I neglected to close the damper after a last few minutes of oxidation. Three hours later I remembered the damper, but by that time the temperature had dropped from 2300F to about 800F. Crash-cooling at its finest and least intentional.
As a consequence - I think - most of the usual carbon-trapping I get with one of my favorite Shino glazes was not there. Fortunately, I'd sprinkled wood ash on a number of those pots, so that the surfaces - though quieter than usual - actually have some nice, subtle things going on.
The other concern of having a bunch of Dan Finnegan demonstration pots in there turned out not to be a concern at all. Dan's pots look just fine - temmoku on a number of them, a few glass runs, one or two with copper red, a nice ash celadon on a tall vase, and even some delicate webs of carbon-trapping on a fine mug. All of these pots will help the Cape Cod Potters raise a bit of money for the CCP education fund. Thank you for that, Daniel.
I'll attach one photo of some of Dan's pots here and later today or tomorrow put up some of my own.
