7am 100oC gas up, weather is still, overcast and damp
9am 310oC gas still on, damp wood, damp kiln, did not do a warm through yesterday, kiln steaming - low fat pots?
10am 480oC gas off, hard work to keep this fire going. Am I tired? not really enjoying this
11am 616oC south west breeze. Now the fire is more beguiling, it becomes a reason in itself to continue. The kiln has ceased steaming
1pm 878oC using large slab wood, strong s.w. breeze
1.30 1004oC reducing for a good half hour
3pm 1088oC first soda in. Cold s.w. wind blowing into fire mouth,
3.30pm closed the big doors for shelter
4pm 1088oC then at 4.05 up to 1126oC
5.30 1165oC Andrew stopped by, just to check that the flames were intentional
6.30 1200oC cone 7 bending
7pm 1203oC cone 8 bending, 7 down
7.45 1187oC cone 9 beginning, cone 8 down
8.15 1220oC cone 9 down, last big stoke, start clamming up the kiln, a few slivers of wood added during this.
I didn't make a note of when I put the fire mouth door on, probably around 1000oC to assist the reduction. It made a big difference to the comfort of my knees which would be scalded without the door. It was along hard firing this one, the longest so far at 15 hours, damp wood, cold south westerly wind all having an effect. The rain held off. I thought that the wind in this direction would speed it up as it blows directly at the fire mouth, my perception is the opposite. Will have to try it again with drier wood.
|happy kiln = happy potter,|
will post some results next.
I think this blog is getting repetitive, not enough crises with this kiln. By the look of the interior it will need a rebuild before the chimney wall slumps.
Meanwhile I have been planning an anagama firing at Higham Hall in Cumbria for November.
