This jar by Alice Cling has a water jar shape with a round shoulder and square neck. The sides of the neck has been squared off so that it is flat on the sides.  The jar is then traditionally fired to create the coloration.  Note how the fireclouds swirl around the jar creating areas of dark black to deep red.  The jar was covered in pine-pitch after the firing, a continuation of the traditional Navajo pottery when pitch was used to make the pottery waterproof.  The jar is signed on the bottom in the clay, “Alice Cling”.  Alice has won numerous awards for her pottery and been featured in books such as “Legacy of Generations.”
