Interest in color science has grown with the increasing number of colored products which are manufactured and with the increasing awareness on the part of industry of the role that color plays in the marketplace. But along with this awareness has come the realization that producing colored materials presents many frustrating problems and that the solutions lie outside of the knowledge of most technically trained people-color science is not taught at most universities. So there has been a great need for an elementary book which considered the science of color from the point of view of the needs of the industrial worker. This book goes a long way toward filling this need. Elementary aspects of color science are presented clearly and concisely, making it particularly valuable for beginners. The recent advances in the applications of color technology in industry that have come about with the advent of computers is summarized. But perhaps the most valuable aspect of the book is the consideration given the practical problems associated with the manufacture of colored products. The basic principles of color and colorimetry are presented in the first two chapters. The third chapter deals with color measurement and tolerances and specifications. The next three chapters are a discussion of the problems of selecting colorants and of formulating and nianufacturing them into a finished material. Here the authors consider many aspects of the processed coloration not found in other books on color. The techniques of using computers in formulation and control, the factors limiting the gamut of colors available such as colorant performance and Cost, the sources of information helpful in colorant selection, and the Circle NO. 14 on Readers’ Service Card VOL. 5 9

practical difficulties and costliness of making exact color matches are examples. Chapter Seven consists of an annotated bibliography of major references which is invaluable to the beginner. The authors have not included many of the aspects of color science which have been treated in other books about color-the reader will not find any discussion about color vision theories, anomalous color vision, color vision or discrimination tests, or of the affective attributes of color. The authors do point out the complexity of the visual process, and particularly stress the importance of adaptation, referring the reader to other sources for more detailed treatment of the subject. They point out the importance of aspects of appearance other than color on the total color response, but do not take up this problem in this book. The book is short-144 pages of actual text-and is profusely illustrated with diagrams and pictures, marginal notes and addenda (such as Peanuts cartoons), which illuminate the subject brightly. The style is informal and the tone is conversational and very readable. It is well indexed. The book’s one fault comes from oversimplification of certain concepts which results in some confusion, but this stems from the authors’ laudable desire for conciseness, and is, in the total picture, minor. The book should find wide audience among laboratory and production people as well as in management where color problems are of concern. Ruth M. Johnston

Coating fertilizer pellets so they are free.flowing in the bag makes a better product. but it‘s no easy trick. The secret is in the design of flights to thoroughly mix and blend the coating agent (clay, diatomaceous earth, Fuller’s earth, etc.). If you look closely, you can see how the serrations in the bottom of the flights allow the coating agent to also fall through the flights for better mixing-blending in this Rotary Blender.
