elaine clapper Posted November 2, 2015 Report Share Posted November 2, 2015 I have a question on "holding" time with an electric kiln. One of the glazes I use fires matte at cone 5 and glossy at cone 6. I would like something just slightly more cone 5. If I set the kiln for cone 5 and set it hold for an hour at the peak temperature, will I get a slight temperature increase? hold it for more? less?

Min Posted November 2, 2015 Report Share Posted November 2, 2015 Usually 45 - 60 mins soak at top temp to bring the next cone down. YMMV Link to comment Share on other sites More sharing options...
bciskepottery Posted November 2, 2015 Report Share Posted November 2, 2015 If you can, start with 15 or 20 minutes hold. If that is not what you want, add another 15 or 20 minutes on the next firing and repeat until you get the surface you want. Your surface may be more like 5 1/2. And you may have to adjust as your elements and thermocouple get older and less efficient. Link to comment Share on other sites More sharing options...
neilestrick Posted November 2, 2015 Report Share Posted November 2, 2015 I'd start with a 10 minute hold and increase in 10 minute increments as needed. Link to comment Share on other sites More sharing options...
David Woodin Posted November 3, 2015 Report Share Posted November 3, 2015 I have a question on "holding" time with an electric kiln.

If I set the kiln for cone 5 and set it hold for an hour at the peak temperature, will I get a slight temperature increase? hold it for more? less? An hour soak at a ramp of 108 deg F will bring down cone 6.(2230 F) A 17 min soak will bring down cone 5 1/2 (2201F) . So it would be better to try what Neil said and start off at 10 min soak at cone 5 ( 2176 F), which would be about 14 deg F higher than cone 5 down+14= (2201F).
