offcntrMad science report:
Hard as it was to wait, I didn't open up the saggar firing until the rest of the kiln was completely unloaded, Denise and I'd had a lunch break… and Shelly arrived to see how our experiment had come out.
Results were great fun--some lovely amber-colored flashing on the porcelain slug, with speckles where we'd dusted the copper. Also a brown, ashy glaze on the snail, bunny, and whistles that seems heaviest near the bottom, tapering to almost black on the top. We're speculating on the presence of soda and silica in budget charcoal briquettes, since we certainly didn't sprinkle in that much soda ash.
In any case, Shelly's excited to start making more things out of cone 10 porcelain, and I'm kinda tempted, myself. I've actually got a couple of bags, rock-hard, but if I start slaking them now, maybe by my January firing I'll have some more things to put in the box.
