This is an exceptional large polychrome jar by Blue Corn.  Blue Corn began by making black-on-black pottery but it is her polychrome potter for which she is the most famous.  This tall water jar is fully polished tan and then it is painted.  The black is a black clay and the red are additional clays.  The shoulder of the jar has a feather pattern and the neck has alternating geometric patterns in each section.  The lines are perfectly painted and match the shape of the jar.  The intricately painted neck is unique in her design and not something we have often seen yet it emphasizes the elongated neck.  The jar is in excellent condition with no chips, cracks, restoration or repair.  It is signed on the bottom in the clay, “Blue Corn”.
