Pottery by Cole

5” x 3.75”

Soda-firing is the process in which sodium oxide (soda) is introduced into the hot kiln. Once inside, it will vaporize and interact with the red hot surfaces of the work leaving beautiful flashes of color and glaze. As the sodium vapor flows through and around the glowing hot pottery, it binds to the silica molecules on their surfaces to create a glassy glaze which tapers into gradients of color called flashing. Since the soda fuses to the surfaces of the work in this way, it blurs the line between pot and glaze/surface; they become one.
