However, I am surprised he did not mention alkaline glazes, which are common in his neck of the woods...though mainly in the 19th c. and never (I think) on refined white wares. If you're not used to seeing these, they can appear to be salt-glazed. They can be produced at lower temperatures, I believe. >> The alkaline glazes we see here in SC are on stonewares. Under poor firing conditions they can be rough, but they lack the characteristic dimpling of salt glazed wares. Some varieties of clear alkaline/feldspathic glazes were used on industrial earthenwares in the 19th century, but those that we see here are definitely green. One might refer to Charles "Terry" Zug's "Turners and Burners" (UNC Press) for more info and some good color plates. John Burrison's "Brothers in Clay" (UGA Press) is also very good. By the way, when I referred to possible unglazed White SGSW I meant thinly glazed or unglazed sherds--which would only be a small part of the vessel overall.
