In every kiln firing, there is usually one piece that comes out better than you dreamed. Some people call them "Racers".
Here's my racer.
This thing has been setting around on a shelf waiting to be fired for a long time. It's big. There hasn't been a firing that allowed a free shelf, so this piece got put off and putt off.
But this guy made it into the OVERFIRE kiln. Yikes. All these glazes are supposed to be good up to cone 6. I don't know how hot the last kiln got because the thermocouple malfunctioned. The chances of duplication? almost nil.
It did blister a bit, but no explosions or craters.
I just love it. It's a keeper.
