The Yangshao potter's wheel theory is on p.388, but I've always heard that the Longshan were the first to use potter's wheels (China not having invented the wheel anyways).
EDIT: I found some more information on Rice's Pottery Analysis, Second Edition: A Sourcebook p.15
There is little evidence for the beginning of the use of the potter's wheel in China. It has been suggested that a low, thick-walled, dish-like vessel commonly found at Yangshao sites between 4800 and 3600 BC may actually have been used as a tournette, a slow or low-speed wheel (Zhou Zhen-xi 1985). The fast or true wheel was apparently used during the Zhou (Chou) period, roughly the first millennium BC (Hobson 1976:2).
Still welcoming more information though!
Couldn't find much more than you did except this article which looked at the technological aspects of a sample of Yangshao pottery and determined some of it had been "wheel thrown".
Whether that is a true potter's wheel or a foot wheel/dish (a tournette) like Rice suggests is an open question but I would bet on something like the latter.
For example, in this footage of Ethiopian potters (starting 4:30) as a pre-wheel method of throwing pottery. I've also seen variants that are essentially a plate balanced on a rock and turned with a foot. Either way, a tournette would produce pottery that looks similar to truly wheel-thrown pottery and perhaps what the article I linked to above is picking up on in some of the Yangshao pottery. This is especially compelling given that not all the pottery they examined had evidence of being wheel-thrown, since this is a common pattern in pottery produced with tournettes - only a subset of the pottery (usually based on form) is produced with the tournette and other forms are produced without.
