Kathy Butterly’s work is notably undefinable, and that is its strength. The artist’s current exhibition of 24 new ceramics at James Cohan Gallery in Chelsea, which closes on October 20th, exemplifies how Butterly’s forms constantly fluctuate. Butterly’s materials--clay and glaze--are never used in a systematic or repetitious manner, which allows chance and experimentation with molding and the layering of glazes to guide the ceramics into being.
