Elements of Ceramics. By F.H. Norton, Addison - Wesley Publishing Company, Reading, Massachusetts 2nd edition, 1974, 312 pp.

Ceramics are materials that strongly affect many aspects of our life. The author clearly states these points through 23 chapters of the second edition of his book 'Elements of Ceramics'. The book is wrote for undergraduate students and it is particularly aware of the evolu- tion of the ceramic industry in the United States. An evolution that twenty years ago - the period relevant the first edition of this book - was not possible to foresee.

The author's purpose of covering and dating as thoroughly as space permitted new products and processes as well as the traditional ones, is the limit and the value of the book. Too many aspects of rather appealing but sometime extensive problems have received low attention; however what it has been lost in depth it has been gained in extension, and for the user that first approaches such uge field this kind of 'ceramic panorama' can be really useful.

In principle all students in Metallurgy and Materials have to
