Valarie Posted January 31, 2021 Report Share Posted January 31, 2021 I had to shut down my 05 glaze firing after only 2 hrs,due to a ventilation issue. Can I restart this glaze firing? How much damage did shutting the kiln down to soon have done ,to my pieces? Thanks any help would be appreciated. Link to comment Share on other sites More sharing options...
Bill Kielb Posted January 31, 2021 Report Share Posted January 31, 2021 No damage from shutting down, start it up. I doubt it got to a very high temperature. Tell us if you know but short of 1400 degrees for cone 05 I wouldn’t even be concerned. The majority of the work on a glaze fire is done in the last 200-250 degrees. Pretty much everything before it is “reversible” if you will. What was the reason for the ventilation issue? If wax burn off then it should end 800-900 degrees. If paper, etc.... in sculpture work, it should ignite about 400 degrees and can be fairly Smokey. You will likely need ventilation after the restart.

Valarie Posted January 31, 2021 Author Report Share Posted January 31, 2021 Thanks, the temp was 726 ,I had lowered the temp ,becsuse I thought it was ramping up to quickly.I have a Duncan ES820-2 kiln.It is older but I have done 2 bisque firings and one 05 glaze firing with no issue.The only differences this time is I had a heavily packed kiln with 2 and half shelves .So there were 2 pots close to the lid top.It is also very windy outside and we have 500cfm vent system blowing out from the basement and another smaller exhaust as well in an open window .We thought the wind was possibley pushing the fumes back into the basement.
