This is a classic fully polished open bowl by Margaret Tafoya. The bowl is coil-built, stone polished, and traditionally fired black.  The bowl is from the 1960s and it is fully polished on the inside and outside. The bottom is matte.  It was fired a dark black coloration.  It is signed on the bottom in the clay, “Margaret”  It is in good condition with no chips, cracks, restoration or repair but some slight surface scratched on the inside of the bowl.  I priced it based on condition.
