Found a book in the library which would be of interest to
enamelists. “English Enamel Boxes: From the Eighteenth to the
Twentieth Centuries” by Susan Benjamin, Orbis Publishing,
London, first published in 1978, reprinted 1980, 1981, 1983. It
is now out of print, but I’d think your local library could find
a copy. Amazon.com has found me a copy for purchase. The
contents are history & techniques of enamelling, manufacturing
processes, a discussion of the various areas (Battersea, London,
Birmingham, etc.) where these were produced, and more. It makes
interesting reading for anyone obsessed with enamels. A rich
history with notes as to where one might find some of the "lost"
processes. I’m in a unique position of perhaps being able to
find some of the original texts here in England, so I may just
be off on a research adventure!
The ISBN is: 0 85613 038 9 in case that will help your search
for a copy to read.
I’m spending this week MOVING into our house here! Oh joy, tons
of boxes to open & a new “studio” to organize, so I can get back
