I also noted that the kiln is firing a bit cooler this time, so that's another reason to speed up the ramps and temps.
The old schedule was:
Ramp Temp To Temp Hold Time
1 50 200 2 hrs (2.00)
2 80 350 2 hrs (1-6) depending on dampness and pack
3 90 1200 0.00 kiln will go until timp reached
4 250 1944
New Schedule will be:
1 50 250 2 hrs
2 80 500 1-6 hrs
3 90 1200 0.00 (until temp is reached)
4 250 1944 0.00
*I have to put this in to be sure I hit that start button to begin the firing--can't tell you how many times I didn't do this and couldn't figure out why the kiln wasn't firing. heh
Kilns are always evolving. I have noticed that this kiln is beginning to fire a tad cooler, so I can up the ramps and, if it fires again to 05, I will increase the target temps to compensate.
This is why it is really great to keep good notes about each firing--this was a loose pack kiln this time--so I know that if I fire a load that is really full and tight, I should up the final temperature to make sure the ware gets bisqued well.
It can be critical when it comes to a glaze firing because of those glazes you know only work well at certain temperatures.
With all the variables that come into play with clay work, it's a wonder we even pull it off sometimes!!
