Soda Kiln Firing






















Here is some of the process of loading and firing the soda kiln. The kiln that I fire the most is small, so that I can turn over the work fast and respond to glaze and firing applications. This was a good firing for the most part. Some glazes didn't do what I expected, but maybe if I wait awhile, I'll come around.
The picture of me stacking the door shows the scale of this particular kiln. I have a larger soda that takes two days to glaze and load, plus a reduction kiln.
The last picture is of me squirting in the baking soda that is dissolved in water. The soda solution interacts with the silica in the clay and turns it to glass. The soda also helps create flashing and flame patterns.
