Tina Diaz is a daughter of Mary Cain and a sister of noted potters Joy, Linda and Billy Cain.  She makes very few pieces of pottery each year and this is one of the intricately carved black pieces.  The jar is very thin walled and fully carved.  The design is a series of two old style dragonflies.  They are separated by a cloud design and a line representing rain carved into the neck.  The neck is slipped with mica.  The carved areas of the jar are either stone polished or matte with a mica slip.  Note how her designs are very fluid from top to bottom.  As well, the background area which is matte is “rounded”, which adds another dimension to her pottery!  The jar is signed on the bottom in the clay.
