- The cone pack exploded because
- I made the packs just a few hours before lighting the burners
- I didn't poke vents in the clay of the pack with a needle tool, to allow the water vapor to escape more easily; and
- I turned up the burners too quickly
- The burner fluffed out repeatedly because the thermocouple was failing. That's nobody's fault - thermocouples don't last forever - but usually I have extras around.
- I forgot to buy wood shavings and soda ash ahead of time
- And, as I was reminded when I unloaded, I forgot to do my basic kiln hygiene and knock the stalactites off the underside of the arch! These turn into ugly, lumpy grey-green drips in the firing, and I lost some pots on the top shelf to them.
All in all, though, I have to say I was incredibly lucky. The soda glass is evenly distributed, the colors are rich and clear, even the exploded cone pack didn't damage anything! Most importantly, the steins that I need for Watershed's Salad Days event came through beautifully. (Enough of them, anyway! One was lost in the bisque to a separating handle, and two got the aforementioned ugly soda drips on them. that still leaves more than I need!)
- 4 am - red heat, turned up burners
- ^012 falling at 7 am, turned up burners & pushed in damper
- G-D f*ckin burner went out about 4 times between ^012 & ^3
- ^6 falling at noonish - started adding soda mix
- Kiln stalled for over two hours at ^6. Stopped adding soda & put kiln in lightest possible reduction
- ^8 falling, resumed soda. Finished soda maybe an hour before the kiln went off
- Had only one cone pack, in the typical hot spot, so I laid ^11 down to make sure the cool spot got to ^10
