here's a tip if you're just starting out or if you've gotten lazy about your firing.  Keep a log of how long it should take you to fire your average load.  If it usually takes you 9.5 hours to bisque under normal circumstances and the kiln's been running for 13, something's wrong.  Maybe the little cone that sits in your kiln sitter has melted and stuck to the sensing rod so that the kiln keeps firing to cone 7, leaving you wondering if you should try to glaze the now-vitrified pots or not.  I unloaded my kiln (including one shelf that warped, so maybe -probably- the kiln got closer to cone 10 - that's 2300 degrees, folks.  I usually only fire to cone 6, which is in the 21-2200 range.  this load should have shut itself off at 1800.), test-glazed a few pieces, and went back to bed.  Yes, I called it a day and slept until school got out. 

I've noodled around for some tips and tricks on getting the glaze to stick and I'm willing to try them, but the problem is that once clay has vitrified- meaning that it is as hard as it can get and the pores in the clay are closed- the water in the glaze doesn't absorb back into the clay.  Usually you dip or brush wet glaze onto a piece and all of the water is sucked into the clay.  When the clay is vitrified, the glaze- and water- just sits on the top of the piece. 

Yes, I still feel pretty peevish about the entire thing.  So my plan of action is to test a few pieces and run the kiln again tonight to see if the kiln sitter will work or if I will need to fix it- which would be a handy thing to learn to do.  It's always something, isn't it?  And I'm going to put a log up next to the kiln so that I'll know how long each firing should take and watch it more carefully. 

Yes.  My pieces from Atlanta were in this load.  I lost one of them- the color that I'd used turned completely black.  Not pretty.  The other ones seem to be ok.  So this setback, trip-up, whatever is a learning experience.  I'm going to stop being so irritated by it and pick myself back up and carry on. 

I'll be back.
