I have an 1831 pamphlet from the "Library of Useful Knowledge" published by
Baldwin and Cradock in London entitled "On the Manufacture of Iron". On page 3
it has a picture of a "more simple form of constructing furnaces, which has
been resorted to in Wales, and which is called a cupola. It is in the form of a
large chimney, and from the boshes upwards is simply the length of a single
brick in thickness. It is held together by an iron hoop at every join."
Any idea when did cupola type foundry furnaces get introduced? Peter King seems
to feel it may have been after 1775 by Wilkinson.
