I've checked out Robin Hopper's videos on form and proportion from the library before, and was happy to see much of the same material expanded upon in this book.
This book covers all kinds of kitchenware, plates, mugs, bowls, goblets, butter dishes, pitchers, teapots. He also covers proportions and esthetics of form, along with praticalities like center of gravity, weight, and making things 'fit' the human body for use.
He also has a broad definition of 'funtional' pottery that isn't just dinner service, but includes decorative ware that serves as objects of beauty and contemplation.
