Press Opinions.
"This work is of the highest technical character, and gives not only a full and practical account of the raw materials and manufacture of glues, gelatines and similar substances, but gives many hints and information on the use of such substances in veneering, carpentry and many other purposes. Many tests are given for glue in different stages of the progress of its manufacture, and the commercial value of a commodity so much in general use is exemplified by statistics and figures. It is certainly a valuable treatise upon an article for which very little literature in any form has previously been obtainable."—Carpenter and Builder.
"Books on the art of glue making are more than usually scarce, and users of that article, as well as those who may be tempted to embark in the industry, should therefore welcome this book by Dr. Samuel Rideal, a Fellow of the Institute of Chemistry, and a leading authority. In this book he has collected the more important facts connected with the manufacture of glue and allied products, and stated the experience he has gained in examining various commercial samples during the past ten years.... Dr. Rideal's book must be regarded as a valuable contribution to other technical literature, which manufacturers, merchants and users may study with profit."—British Trade Journal.
"This volume is the latest addition to the excellent series of special technical works for manufacturers and professional and commercial men issued by the well-known publishers of The Oil and Colourman's Journal. The volume in every way fully maintains the high standard of excellence of the whole series, and deals with the subject of glue making and glue testing in a thoroughly exhaustive manner. Chapters are given on the constitution and properties, and raw material and manufacture, and of the uses of glue, and in this latter respect it will doubtless be information to many readers to learn to what extent glue enters into the manufacture of many commercial products not apparently associated with glue. Exhaustive chapters on the processes and methods of glue testing, and on its commercial aspects, complete this useful and most carefully prepared volume."—Carriage Builders' Journal
