The Science And Technology Of Gelatin PDF Download

Excerpt from The Chemistry and Technology of Gelatin and Glue The dearth of reliable information upon the manufacture, testing, analysis, and general applications of gelatin and glue is felt keenly among students and investigators who are desirous of acquainting themselves with the principles of this industry. The books that are upon our shelves have not kept up with the latest developments and improvements in the art, and much information that is found in the literature is astonishingly inaccurate. But of even greater importance is the failure of previous writers to meet the issue of the chemistry of gelatin and glue. An enormous amount of very important and suggestive work has appeared during the past decade in the scientific literature dealing either directly or indirectly with the chemistry of gelatin, and it is in the correlation and summarization of this material that the author feels his work is most completely justified. The attempt is made throughout the book to attack the subject from the point of view of the chemist rather than from that of the plant technologist, and it is primarily for the student and investigator, - the thinkers ahead, - that the book is written. There is no field of research that is more rich in highly interesting problems awaiting investigation than that of the protein colloids, of which gelatin and glue are the most conspicuous examples. We have but to point to the recent book by Wilder D. Bancroft on "Applied Colloid Chemistry," to cause a seemingly unending procession of such problems to rise before us and to beckon us on to master them. There is no dearth for study here. And it has been the constant aim of the present author to indicate lines upon which further investigation would be highly desirable. The advance in the principles of industrial research that has been made during the past ten years is a seven-league stride when compared with the meager progress previously attained. Industrialists have been slow to appreciate the value of chemical research, and to those among them who have had the vision to foster it, too much credit cannot be given.
