SOME SIMPLE, PRACTICAL TESTS FOR GLUE USERS
To perform the tests described requires a degree of experience and an equipment beyond the reach of the ordinary buyer and user of glue.

These tests could not be used as a basis for grading glue scientifically, but they are exceedingly valuable in determining its purity and its adaptability to the work in hand.
