Looking at your return address, are you putting us on?
Anyway, I believe one of the best books is the one by Margaret
Seeler entitled “The Art of Enameling”. I like it because of the
how to assemble portions.
Another available in soft-cover from Dover is “Cloisonne’
Enameling and Jewelry Making” by Felicia Liban and Louise
Then there is the Herbert Maryon classic “Metalwork and
Enameling” also from Dover. This is an outstanding book and my
favorite. Has some very interesting techniques.
There are many more good texts. Enjoy enameling.
