#12022 Seeing witness cones

Posted by Natas Setiabudhi on 08 January 2012 - 08:07 AM

Hi stuart
Ya it's common problem for the potters. Usually if the atmosphere not reduction the cone will be seen clear enough. I have simple way to solve that problem, just blow it. So you just closer the peephole and blow it for several times. But remember don't too close, your mouth will burnt. I will guarantee it will be succeed.
I usually put the small test piece glazed beside the cone to make sure glaze melted well. The piece have a small hole so you can draw it by iron. You will see directly the glazes are melted well.
Okay good luck!

#11730 temp for opening kiln?

Posted by Natas Setiabudhi on 03 January 2012 - 04:04 AM

Every kiln has uniqueness, you can't generalize it or any method about the kiln such as firing method, increasing temperature, etc. Even in same size of the kiln, potentially different for each other.
Usually the kind of clay determines thermal shock strength. Clay consists a lot of free quartz you must be patient for opening the kiln, but for earthenware you no need worry to much. Also the pot in slip casting technique is more stronger then other technique such as throwing or slabbing in thermal shock phenomena.
I usually open the kiln in step by step. First I open the spy hole. Than if fell warms in your hand, I open the door kiln just little bit. Every a half an hour I open just little bit too.
