One of the clay classes is firing the wood kiln. They spent about two days loading, then started the firing yesterday. At dinner there were rumors of s'mores at the wood kiln, so of course I had to investigate. And I can hereby report that the rumors were indeed correct. They even had little wooden skewers for roasting the marshmallows (which you could then throw away in the fire box).
The kiln was at 500 degrees when I stopped by, which is apparently mostly past the point where pots explode due to moisture content, but the kiln will get up to 2400 degrees before all is said and done. For the first 500 degrees, they increased the temperature 50 degrees per hour, but as of 7pm last night they were going to increase the rate to 100 degrees per hour. I don't know if they've changed the rate since then. But I know the firing will be continuing for a while yet. And the cooling will take even longer.
