HOW TO SELECT PREPARE AND USE GLUE
A SHORT, PRACTICAL DISCUSSION OF MATTERS IMPORTANT TO EVERY GLUE USER
J. A. TAGGART, TOLEDO, O.
The purpose of this manual is to provide a practical guide for glue users, to help in eliminating waste and improving the quality of product.
That there is an enormous waste due to improper preparation and use of glue is well known to all who are in touch with the subject.
Some authorities estimate that 70% of the glue used in the United States is improperly handled. The actual waste is said to be in excess of 25% of the amount of glue used; to say nothing of the loss due to imperfect condition of the completed work.
The writer knows from actual experience that many glue users are ignorant of the proper methods to be employed; and that many others are careless, or indifferent.
The handling of glue is a subject on which much new light has been shed in recent years. There is no longer any reason why the glue user should not know the correct methods to follow.
