Cone 6 Oxidation Results Group 5

Cone 6 Oxidation Results Group 5

Thus far I have batched over 120+ different glazes in 300 gram batches, the formulas for which have been found from publicly available sources. After firing these tests in an electric kiln to Cone 6, I have photographed each and am making them available to potters with the accompanying formulas.

One difference with this Group 5 is that I have introduced a cooling cycle to the firing. The cycle is as follows and the firing is accompanied by a Cone 6 witness cone. After 12 consecutive firings, the witness cones are identical from firing to firing.

The firing cycle:

Rate	Temp	Hold Time
rA1= 360	F1 = 900	0
rA2= 300	F2 = 1800	0
rA3 =200	F3 = 2016	0
rA4 = 108	F4 = 2197	0.3
rA5 = Full	F5 =1800	0
rA6 =150	F6 = 1300	0
rA7 = 0000

To summarize, I fire at a rate of 360/hr to 900 degrees F, then at 300 degrees/ hr to 1800 degrees F, 200 degrees/hr until 2016 degrees F is reached, then 108 degrees/hour to 2197 at which time I hold it at that temperature for 30 minutes.

The kiln is shut off until a temperature of 1800 degrees F is reached and then turned on to slow the rate of cooling to 150 degrees/hr until 1300 degrees F is reached. At this point the kiln is turned off and cools naturally.

I use a Vulcan kiln controller attached to a Paragon QA11 test kiln. The combination of new elements in the Paragon and new thermocouple and controller has produced consistent heat work from one firing to the next.
