Workshop Notes

Firing #13 notes

Michael Kline

Just shut off the gas valve to the soda kiln for the 13th time. This is a kiln I had hoped to fire last week before our Cousins in Clay  pottery show last weekend. But my best laid plans succumbed to the particular technical circumstances and the time reality continuum. But the pots are now fired and settling into their new ceramic formations.

I let the kiln cool very quickly to insure that I can unload them on Thursday afternoon. I did this by leaving the upper soda spray spy openings wide open, while sealing up the burner ports, letting the heat naturally and safely escape through the chimney and these open ports. 

Where I tried to make adjustments to move the heat to this top front area of the kiln. The pyrometric cones melt at specific temperatures over a certain amount of time. After an hour of trying, I only got incremental increase in temperature and had to call it. Maybe the heat was blocked by constricted stacking of the kiln. But it wasn't worth continuing and take the chance of overheating the rest of the kiln.

The successful pots from this kiln will be on display at the 13th annual Potters Market Invitational September 9th in Charlotte, NC. 

I look forward to seeing everyone there!
