Firing Schedules

My Present Firing Schedule:

Began use at: 10/20/2012:

200°F/hour to 220° hold 30 minutes
400°F/hour to 2100° no hold
100°F/hour to 2180° 60 min.
40°F/hour to 2140° 30 min.
300°F/hour to 1700° 60 min
50°F/hour to 1600°  - off
I slowed the cool-down at the top end and put in additional soak at 1700° toward the end to address some pin-holing some of my glazes were having. This opened up a new look in my SCM / Randy's Red combination. Lost the matte and gained a gloss (that seems inverse of rule of thumb). The gloss is more food friendly. And I gained additional color response.
Firing schedule until:

200°F/hour to 220° hold 30 minutes
400°F/hour to 2100° no hold
100°F/hour to 2180° 60 min.
100°F/hour to 1700° hold 60 min.
50°F/hour to 1500° hold 30 min then off

This yields some nice crystal growth. Some surfaces seem drier but I think that can be modulated with the amount of SCM I apply. We'll see. It seems like I'm getting some wonderful iron conversion to pyrite (reflective gold-colored crystals in the glaze).

I wasn't getting the rich colors by letting the kiln cool naturally to 1700° so I fired down at 400° per hour.

Firing Schedule until 2/18/12:

200°F/hour to 220° hold 30 minutes
400°F/hour to 2100° no hold
100°F/hour to 2180° 60 min.
400°F/hour to 1700° no hold
50°F/hour to 1600° 30 min then off

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.

Pete Pinnell firing schedule for Tomato Reds:
Ramp 1: 250° F per hour to 2000° no hold. 
Ramp 2: 100° F per hour to 2170° F (come 6). No hold
Ramp 3: 150° F per hour to 1900°. No hold. 
Ramp 4: 50° F per hour to designated soak temperature. 

Hold soak up to three hours

Switch off.

Wow, you did a great job on you profile page, Robert. Did you know that you can take the profile question, "What is your current involvement with electric fired ceramics?" and turn it into an extended autobiography? (or you can let your pots speak for themselves)

I found the SCM glaze formula! THanks, I will keep looking, I am figuring out this web site.

I am new to the site, remind me what SCM is and where I might find info (formula) for it and the other glazes you use, if you are willing to share. They are beautiful. Thanks. The beer steins are incredible.

Pleased to meet you!  Your work is beautiful.  I am an intermediate level potter and only have available to me cone 6 electric kiln and am craving the look of cone 10.  I love your glazes and just now I think I noticed that you usually use porcelain.  I do not but I joined this site to hopefully get tips on getting the look I want.  Still trying to find my way around the site!

Also, these glazes are well behaved except for the ash, they don't run.  Put the Petes on thickly, otherwise it's a pretty ugly brown.

I find that the Pete's is dry, but beautiful, especially if you use the SH firing schedule with a slow cool.  What color is your clay body?  It looks like you used the Pete's in the very center.  What is the blue color in the rim area?  Try layering the Petes with the Watercolor green and the strontium for light colors for some very wowie effects!

One door closes:

We were notified the property was being sold and we would have to be out Aprl 13.

After anguished panic we reasoned we would need to liquidate the studio. We just couldn't move the studio again. We are going to sell about 90% of the studio's inventory. Wheel, shelving, pug mill, chemicals, buckets, barrels, batts, molds and so on. Looking south for housing and studio space Rita took a look at AMOCA where we already have a presence in the Museum Gallery.
