text_A: Pottery making began in the 7th millennium BC. The earliest forms of pottery have been found at the Hassuna site and were pots formed by hand from slabs of reddish-brown clay that were low-fired and lacking in glazing or decoration. Within the next millennium, wares were decorated with elaborate painted designs and natural forms, incising and burnished.
text_B: Does the passage imply that even the earliest uses of pottery had some sort of aesthetic or even food-related purpose that would necessitate some kind of sealant around the fired clay?
NO.
