Nicolasa Naranjo was a daughter of potter Tomasita Tafoya Naranjo and a niece of Margaret Tafoya.  She created a wide variety of pieces over the years of her pottery career, including polychrome pieces as well as black-on-black pottery.  In the 1980s and ’90s, she was often helped by her daughter, Roberta Naranjo (1946-2001).  This bowl is triangular in shape when looking down from the top.  It is painted with a water serpent (avanyu) encircling the bowl.  There are plant designs along with small rounded cloud patterns by the base.  It was fired a dark black.  It is in excellent condition with no chips, cracks, restoration or repair.  It is signed on the bottom in the clay, “Nicolasa + Roberta”.
