It is made from a coarse clay, coil built, and thin walled. It is not scraped to thin it, but it shows indentations of a support mould. Possibly a woven basket that supported the underside when forming the pot. The theory is that the clay was beated thin with paddles when it was leathery hardened.
The piece provenances from Marvin Sadik, recently deceased, who was an important collector and private dealer in Maine, and was formerly the director of several museums including the National Portrait Gallery.
