text_A: Pottery making began in the 7th millennium BC. The earliest forms known, which were found at the Hassuna site, were hand formed from slabs, undecorated, low-fired pots with a primitive glaze made from reddish-brown clays, but it is unknown if even earlier, unglazed forms may have been lost to the elements. Within the next millennium, wares were decorated with elaborate painted designs and natural forms, incising and burnished.
text_B: From what can be learned from the passage, as it is written, is it possible that if earlier forms of pottery were to be discovered, they could be found with a less-advanced form of glazing?
YES.
