ELEMENTS OF GLASS AND GLASS MAKING. A TREATISE DESIGNED FOR THE PRACTICAL GLASSMAKER, -PLAIN AND COLORED. INCLUDING AN APPENDIX CONTAINING USEFUL SUBJECT. BY BENJAMIN F. BISER. CHEMICALLY REVISED BY J. A. KOCH, PHAR. D. PUBLISHED BY GLASS AND POTTERY PUBLISHING COMPANY, PUBLISHERS' STATEMENT. Though much of a fragmentary nature has been written of the making of glass and its history, no attempt has heretofore been made to bring under one cover information which will be of practical worth to those engaged in the manufacture of glass. The purpose of the present volume is to present the essentials of the art in a form of the greatest practical utility. The subject is much too large for the scope of any one book, but it has been the aim to include in this book the essential details, and to constitute a store of authorative information from which the expert and the beginner alike can draw with profit. The book is designed to be eminently practical. Its author is a practical glassmaker, and for years has been an active factory manager. He is a recognized writer on glass matters and has drawn from the practical experiences of a lifetime in the preparation of this book. In preparing the hundreds of recipes contained herein, the author has selected the best of the standard formulas from all quarters, whose worth has been proven by actual practice, and to these he has added his valuable private collection. That the work shall be an authority, all the chemical portion of the manuscript and recipes have been carefully revised by Dr. J. A. Koch, Dean of the College of Pharmacy, of the Western University of Pennsylvania, and the discoverer of several valuable formulas now in use in the glass trade. Dr. Koch in the past few years has several times been commissioned by the most prominent glass firms in this country to go abroad and investigate certain phases 393279 |
