Water Vapor In Kiln

04 October 2014 - 01:53 PM

I loaded my glazed pieces in my electric kiln when they were still pretty damp and may not have candled enough as I usually do in that situation to dry the glaze. I also suspect my electric kiln does not have enough (hardly any except 2 tiny holes drilled in top with vent on) air flow, and am wondering if the water vapor in the kiln could account for the slower firing the kiln experienced yesterday. It usually takes 9-10 hours, and I turned it off at 13 (going to cone 6) because I was surprised it wasn't off. The elements are not popping out of the tracks, etc. and the inside of the kiln looks to be in great condition. It was firing like a champ previously. Has anyone experienced an delay from glazes being too damp in the kiln? I'll unload tomorrow morning and am hoping not to find a mess. Urgh!

 


Your Favorite Pottery Videos?

I'd like to start assembling a list of good and inspiring pottery videos to show to my high school class, but there is an overwhelming amount of stuff on the internet. Which ones are your favorites?


Questions About Firing With Peep Out

05 September 2014 - 08:16 PM

I recently got a new (to me) kiln and find myself with a few niggling questions. It has a manual kiln-sitter shut off:

 

1) the kiln manual says to fire it with the top peep out. However, I have a down draft vent, and I am wondering if this would create too much airflow? If I do fire it with the peep out, should I close the peep for cooling after the kiln reaches temperature and shuts off?

 

2) my glazes were more glossy, and less matte, in my old kiln. I am thinking that the old one perhaps cooled more quickly because it was a smaller kiln with thinner bricks/ not so much insulation. If I glaze fire it with the top peep out and the vent on, might this help bring back some glossiness? Should I leave the peep out and vent on during all or part of the cooling? Or would this create problems because of too much airflow during cooling?

 

Thanks for any thoughts or feedback.....

 


Refiring Question

10 July 2014 - 06:13 AM

When refiring some plates with a regular glaze load the plates cracked (in half) while the rest of the load was fine. I suspect thermal shock. When refiring does one need to heat up much slower with ware that has been previously vitrified?

Course Clay Bodies

08 July 2014 - 06:13 AM

I always admire the course and chunky clay bodies I see used in work of potters I admire (usually online, and usually from other countries). My question is, if one wants to use clay like this, does one have to make it themselves? I am assuming so, since the look is so different from the even and processed clay I've bought here in the states. I fire to mid-range oxidation, and I know the work in the link below, for example, is high fire wood and salt/soda, but out of curiosity: how would one begin? Could one add very course grog to a clay body and get this kind of look? What else might one add?
