This is an unsigned Ohkay Owinge (San Juan) jar is from the 1920’s.  It has a round body and a slightly turned out neck.  In the late 1800’s, San Juan was known for it’s distinctive red and tan pottery.  The top half was polished with a red clay slip, while the lower half was “wet polished” or just polished with water.  That left the bottom half of the jar the natural color of the clay. The pieces were then traditionally fired out doors, which resulted in the fireclouds.  This jar has dark black areas from the firing, in complement to the red and tan of the polished surface.  It is in very good condition with no chips, cracks, restoration or repair.  There is some wear and a slight lean to the bowl, but nothing unexpected for its age.
