This is, as the title promises, a very good foundation for any artist interested doing traditional egg tempera painting, or for any art lover who wants to know more about the medium itself. It covers everything from mixing gesso accoording to traditional recipes, to framing and care of the finished work. For me, though, that's the least of it.
First, it's an incredible reference on the tools and techniques of water gilding. It limits itself to gilding as it works with tempera painting and frames, but is exhaustive within that scope. It discusses everything from the laying the bole ground to burnishing, then tinting the finish. Although this emphasizes traditional tools and materials, the author isn't afraid to use modern aids, like rubber cement masks. By the way, anyone who wants to use scrapers to smooth the gesso ground, as this author suggests, should consult a woodworker's guide for directions on sharpening the scraper. A little extra effort up front makes a world of difference in the scraper's performance.
Second, it's a fascinating historical document. Although the book was written in the early 20th century, most of its recipes go back to medieval times, maybe earlier. Therein lies a potential problem, though. Back then people were a bit less careful about pigments like lead white and mercury-based vermilion. Since egg tempera doesn't keep well in wet form, the artist must use many pigments in their hazardous dry form. The practitioner should review the safety of pigments and techniques very carefully before trying the directions in this book.
Still, it's interesting to read about the daily practice of art, including the artist's relationship to a pigment supplier, from a time so different from our own. The recipes, too, have an antiquated sound. I'm not sure I've ever seen sandarac, for example, let alone the range of colors all identified as "vermilion."
This isn't just history, though. It needs some adjustment for modern safety and materials, but it's a very practical guide to everything there is to know about the many techniques in tempera painting.
