Enameling Principles and Practice

I bought this book to learn about the topic in general, and was well pleased with the information it imparted. When I take my first enameling class in a month or so, I will have enough of a foundation that I won't be too lost. The book is from the 50's and it shows; it had a more scholarly tone to it, which was fine. One complaint is that the images used to illustrate principles were so badly reproduced that they are absolutely useless. Since this isn't a step-by-step instruction book that isn't necessarily deadly, but it would have been nice to see images in detail.
