Posted 16 Jun 2013This is like having my own engineering consulting company.

blower at end of 6 foot flex tube.
Posted 16 Jun 2013I am using a skutt enviro vent system, I have had surprising results. I bought it to help vent, and hoped it would help balance the firing in my Skutt 1027, I have a dual Skutt pyrometer set up. Before the vent system I would have between 50 and 80 degrees from top to bottom after installing the vent it was 10 to 15 degrees. I was surprised I wasn't expecting much and I was measuring top to bottom, if I had measured from the middle to the bottom the difference wouldn't be so drastic. I'm not sure I would buy it just for balancing the temp since I do that manually towards the end of the firing. Denice
How many and what size holes to you drill in the bottom of your kiln when you attach the entire event?
I went through my junk pile and I think I can make myself one for about five dollars of stuff from the hardware store.

Thanks for pointing that out.
Posted 15 Jun 2013From summer of 2011 his schedule for glaze firing if he used bisqued not raw pots:
segment 1 - 200F/hr - 220 - hold 30 mins if you have raw cone packs in the firing
segment 2 - 400F/hr - 2100 - 0 hold
segment 3 - 100F/hr - 2170 - 30 to 60 min hold until ^6 falls, tweaking required
segment 4 - 9999F/hr - 1700 - 0 hold
segment 5 - 50F/hr - 1600 - 60 min hold
segment 6 - 50F/hr - 1500 - Off
He says that since kilns are calibrated differently and he doesn't use bisque pots that the above schedule would be some approximation of what he would use.
Here is a little more recent and slightly different version
Steven Hill 2/13/12:
Ramp 1: 200ºF/hour to 220ºF Hold 1 - 3 hours, depending on the dampness and or thickness of the work.
Ramp 2: 100ºF/hour to 500ºF No hold
Ramp 3: 400ºF to 500ºF/hour to 2100ºF No hold
Ramp 4: 100ºF/hour to 2160ºF-2190ºF 60 Minutes—this temperature is about cone 5, with an hour soak Cone 6 should fall. Not all kilns are
calibrated the same, some adjustment may be necessary.
Ramp 5: 9999ºF/hour to 1700ºF No hold
Ramp 6: 50ºF/hour to 1600ºF 45 - 60 minutes
Ramp 7: 50ºF/hour to 1500ºF No hold, kiln off.
Posted 13 Jun 2013Thanks for the input
Being a welder and a cheapo, I think I will make my own.
