This is an early jar by Nathan Youngblood. The jar is coil-built and the surface is fully polished. The jar has a low shoulder and a fluted or “raindrop” rim.  I wrote in the book, “Born of Fire”:

“Beyond the cultural importance imbued in the shape of the vessel, the legends of Santa Clara Pueblo inspired Sara Fina, and were incorporated into her pottery. On the shoulder of her water jars, a second raised section or “double shoulder” created a “rainbow band,” representing a prayer to prevent the water from evaporating from the jar. She often pinched the clay on the rims of her jars, calling this a “rain drop rim”—the significance was to keep the water sweet and drinkable.”  Charles S. King  Born of Fire

Even the top of the rim is fully polished!  The jar was fired a glassy black.  It is signed on the bottom with his name and his Tewa hallmark meaning “Deer Path”.  The jar is in excellent condition with no chips, cracks, restoration, or repair.
