The second chapter, "Methods of Kiln Construction", is edited and revised. small revisions make the text clearer. An entire section on fiber construction has been added. This section goes into various systems for anchoring the ceramic fibers into place and for placing the fiber at corners, doors, and other difficult spots. Fred Olsen discusses the many difficulties with the present fiber products, concluding that, at present, insula- tion firebrick is best for cone 10 (1300°C) Kilns. Nonetheless, this added section on fiber construction gives up-to-date information on how to use these new materials. It serves an important service to potters who will be using fiber materials. It is part of the reason why the second edition of THE KILN BOOK will become and remain a standard reference For the potter's library.

The chapter “Principles of Kiln Design’ is improved by minor revisions and is expanded. For the potter who plans to build a kiln in a hot desert elevation over 3800 feet (Okanagan potters, take note), the small added section "High Altitude Adjustments” could save many times the price of the book.

The middle chapters deal with the principal types of kilms — crossdraft, down- draft and updraft. For each type historic examples and working modern examples are discussed and illustrated.

Throughout the second edition, the illustrations are explained in captions as well as in the text. The illustration captions were lacking in the first edition. Adding them makes the explanations easier to follow, particularly in the chapters on specific kiln designs. The final chapter deals with electric Kilns. The author's main interest seems to be cone 10 fuel fired kilns and most of the book deals with them. The electric kiln chapter gives much useful information both of a technical and of a general sort.
