The Melting of Glass, Part II. General Discussion at the Manchester Meeting

JSGT_1922_V06_T147_T156

The first discussion on this subject was not only keen but also brought to light many points needing investigation. At least one of the particular matters at issue has actually been taken up as a subject for research since the meeting occurred. This alone would make worth while the continuation of such discussions. Supplementary discussion of the subject proved no less valuable in furnishing a searching test of our knowledge. Several of the questions showed, not only how little we know, but even surprised some glass-makers. Reference may be made particularly in this matter to the question of the standing-off of glasses which to all appearances are already plain.
