OK, for bisque in electric kiln I fire to cone 04 ( 1060 C for you foreigners
)
and it takes me commonly 30 hours!! but, I rarely have a crack. I rarely go over 110 degrees F /hr. Pretty slow huh?, but, it works for me.
In Gas kiln to cone 91/2ish ( about 1290C for you) it takes me about 20 hours total from lighting a match.
Let me explain, I load the kiln the day before and have it ready to go. On morning of firing I get up about 6-6:30 AM to let dogs out to pee and start my PILOT BURNER RING ONLY!. I go back to bed until about 8:30AM and then get up and start burners just a tiny bit. KIln is usually heated to about 180-200 degrees F. by then. I turn up gas a bit each hour until done. I do a hard reduction at 06 and 8 cones. I try not to go over about 250 degrees/hr with gas high fire but it takes closer watching/practiceTotal time to fire is usually tight around 20 hours, usually about 2AM when done! YAWN!!
Electric kiln high fire to about cone 6-61/2 ( about 1230 degrees C) takes about 24 hours for me using the computer control. Pretty easy. I rarely go over 120 degrees/hr. Much slower than EVERYONE fires!! But, rarely a problem.
On cool down I turn back on electric around 1,100 degrees F ( about 600 degrees C)for about a half hour when doing bisque or high fire. I don't do this with my gas kiln because it cools much slower through that range, and, I'm usually sleeping
.
This is how Dale does it!
Thats my story and I'm sticking to it!
