I didn't dry the cone dinosaur out enough...so it blew up at about 450 C.
I take out a brick that is nearly four inches wide at the front of the bagwall by the side of the burner, so that the flue warms up and draws quicker. I forgot to replace it.
I've shut the damper down a bit extra to compensate for the latter, 1080 and still drawing ok.
For the former? I'm going by pyrometer and seat of pants! With the gas being late I couldn't abort the firing, as I need both firings through and out before Sunday night.
It seems to have almost reached that sticky point where it slows down for a while. I don't want to reduce fire it, as there are glazes in there that I need to be green not purple or pink!! I'm still learning, and wish I had a firing buddy. I read all about it and get confused!! Time to have a shared salt firing to learn more.
