Planter: Tiered Green Soda

This piece was thrown and trimmed to highlight the architectural curves.  It was covered in multiple sprayed layers of glaze then soda fired.

Each soda fired piece is one-of-a-kind as atmospheric firings are unpredictable and can yield stunning results.  Soda firing takes an enormous amount of time, energy, labor and resources and is usually a community effort.  In the soda firing process, soda ash (sodium carbonate) is added to the kiln at cone 9 (2300°) and the sodium vapor combines with silica in clay to form sodium-silicate glaze.  The sodium vapor also interacts with the slips and glazes to create amazing, unpredictable results that shift around the piece.
