Happy Mistake ???
Twas Tues evening and the glazing was all done, including the 32 glaze test tiles (16 glazes x 2 types of clay). On went the fire (I use an electric kiln and fire to cone 6 which is around 1223 degrees C for those who want to know). All was progressing well later in the evening. At 7 AM Weds morning, I toddled down to the studio to shut off the vent fan and was surprised to find the kiln still running! My normal fire including the cool down segment of the program takes roughly 12 hours. Not only was it still running, it was still up around cone 6! Arghhhhh! - in checking further, I realized that when I set the 'Hold Time' (time needed at top temp to soak the glaze) to 20 minutes, I had accidentally keyed in 20 HOURS!!!! I quickly stop the kiln, reprogram the ramp down schedule, cross my fingers and hope for, as per my daughter's description, a happy mistake!
