In Topic: Firing Schedules

13 July 2014 - 11:53 PM

Here is my schedule to fire to Cone 5 1/2

 

Rate (F/hour)   Temperature(F)  Hold (min)

 

100                   220                     0

350                   2000                   0

150                   2127                   15

9999                 1900                    0

125                   1400                    0

 

Note that the value 9999 produces free temperature fall

 

This schedule was, mainly, based on Hesselberth's suggestions ("Glaze Firing to Cone 6"). However, I needed to play with the pick temperature because his 2185F produced Cone 7 instead of Cone 6 in my kiln.

 

For bisque I use the built in Cone Fire programs on Medium Speed.

Thank you everyone for trying to solve the mystery. :) I'm now convinced that there was a cheese cutter involved.

And thank you for all the links. Lisa Hammond's work is quite interesting indeed (maybe because symmetry, classic shapes and high gloss are not things that I find especially attractive most of the time).

And while we are at this, do you think the surfaces of those two vases were manually carved?

This has been my experience too: red iron oxide disappearing under a transparent Coyote glaze when fired to Cone 5-6 in oxidation.

Benzine,

 

I use the wide end of this type of bottle opener to gently pry the tiles: http://www.amazon.co...s=bottle opener Versa-Bat has access notches on two opposite sides of the tile bed to catch the tiles.

 

Let the youngsters work with Masonite tiles to get a feel of the system.
