Some Criticisms on the Use of the Autoclave as a Method of Testing Glassware
JSGT 1922 V06 T289-T291
To make the autoclave test really trustworthy it is imperative by some means or other to determine the effects of the attack at different pressures and at comparatively short intervals of time, as by such means only is it possible to trace the progress of disintegration. The method requires a good deal more research, and if work on the lines indicated could be carried out the results so obtained would give more valuable information than is possible under the present arbitrary conditions.
