Not sure what you mean by "agitated," but it sounds somewhat like
black-glazed redware. This is the archaeological category for the type, not
the decorative type listed in pottery manufacturers' records. I have not
seen this category in temporal contexts later than the 1830s.

I have a pottery fragment from Virginia (late 1700s to end of 19C  
context). Earthenware, dark red paste. Glaze on one side is lustrous,  
other side is black and dark brown agitated. I'm pulling a blank, any  
suggestions?
Thanks
