More apprehension is lurking. Why? I realize I have four different clay bodies and glossy and matt glazes for the work I plan to fire tonight. What firing schedule should I use for this glaze fire?
The pieces in the two photos were fired Cone 5 with a 10 minute hold. I don't have those exact schedule right now since another potter fired them for me.
I'll split up the load into at least two, so I won't risk it all in one load. I want a slow cool down so the matt glazes will have a chance to develop. After reading and searching, I've come up with a couple of scenarios.
Schedule One
Seg-Rate-Temp-Hold
1 - 100 - 200 - 0
2 - 350 - 2000 - 0
3 - 150 - 2156 - 15
plug top peep
4 - 500 - 1900 - 0
5 - 125 - 1400 - 0
6 - freefall - 86 - open kiln
Schedule Two
Seg-Rate-Temp-Hold
1 - 60 - 212 - 60
2 - 200 - 1976 - 0
3 - 85 - 2156 - 15
plug top peep
4 - 275 - 1832 - 0
5 - 70 - 1400 - 0
6 - freefall - 86 - open kiln
What do you think? I'm leaning towards the second one, which is an adaption from Digital Fire. The first is my adaption from John and Ron's Mastering Cone 6 Glazes.
Any and all advice and reasons for your rationale are welcome. I'm aiming for cone 5.5 since a couple of the glazes are rated for Cone 5 and I don't want to over fire those. All the clays are rated for 5/6 and a few non functional pieces at Cone 8/10. Comments and suggestions are welcome.
