Dear WO'N: Interesting. Never heard it before. But also there are other
very important things about porcelain. Tt cannot be made from ordinary
clays.It requires special starting materials chief of which is Kaolin,
and it is highly vitrified, leaving no porosity, and
having the strength to be made so thin as to be translucent.

And, tut,tut! A cowrie shell looks like a vulva. The vagina is out of sight.
