I have excavated a late 18th century and possibly early 19th century
Pennsylvania German pottery site in southwestern Pennsylvania. Am
currently writing the site report. It was, unfortunately, a salvage
dig.    Represented on the site were basic utilitarian redware vessels,
glazed on the interior, a small amount of vessels with glazing on the
interior and exterior, a very small quantity of slip-decorated redware
and one experimental, decorative piece. No salt glazing is evidenced.
        I am seeking information on the types of glazes used, as well as their
sources. Lead would have been easily obtainable, but what really is red
lead? Could the potter have obtained white clay? Many pieces exhibit a
thin white coating, but no engraving or other applied decoration. I have
basic general knowledge of potting and glazing, and have consulted Edwin
Atlee Barber's book regarding Pennsylvania German potters, among others.
Additionally, I am seeking information about a hard-fired, thin, not
glazed, redware that I do not think was manufactured here. It may have
been of English origin. I have read where England did export basic
redware in this time period. It may have been made in eastern PA by an
English potter.
        I welcome all comments and input/direction.
