Ruben Rodriguez learned to make pottery from his younger brother, Manuel. Manuel learned by watching and working with Juan Quezada. Ruben seems to specialize in black on black jars using ancient Paquimé designs. He also seems to like making geometric shaped openings in his pots.
Ruben learned how to get that beautiful stone polish from Gerardo Cota. That polish makes his reduction-fired blackware gorgeous. Some of his shapes are reminiscent of water jars produced by Nampeyo of Hano. He sometimes polishes a pot five times to get the black mirror finish he prefers to paint on. Then he adds designs in which everything is highly geometric and all his angles end at precise points. Many of his jars have square or rectangular openings cut into them.
