An Examination of some Current Views on the Detection of Strain in Glass.

JSGT_1923_V07_T020_T024

IN reading carefully through the recent literature dealing with the allied questions of the detection of strain in glassware, and of the annealing of strained glass, a number of statements have been met with which need either qualification or correction. In most of these cases no figures or evidence are given to support the statements, and one is compelled to conclude that in some cases generalisations have been drawn from insufficient data. In order to set on a more sure basis the methods for the detection of strain and its removal
from glass, some of these statements need examination.
