More Doubt and Uncertainty

I'm in the middle of the second firing in the gas kiln - about an hour into the crystalising period,trying to hold the kiln steady at 1040 for the next half-hour or so,knowing that I may already have blown it by allowing a little reduction to creep in [but maybe it wasn't that much] on the way up to the top temp [but I can't get anything like a decent kiln speed without what looks like a tiny reduction [a faint small orange flame licking out of the spy-hole,though no sign of a flame at the chimney]. So I'm proceeding regardless,and tomorrow all will be revealed.
