The Effects of Magnesia on the Resistance of Glass to Corroding Agents and......

JSGT 1922 V06 T101-T107

The increasing tendency to introduce magnesia as one of the alkaline-earth bases in glass batches makes it of particular interest to assemble as much detailed evidence as possible of its effect on glass. Glasses as widely apart as common bottle glass, electric bulbs, and chemical glassware have all in recent years been made with a considerable proportion of magnesia present, in company, in most cases, with a rather larger amount of lime. The question has been raised from time to time, especially concerning chemical glassware, as to whether lime or magnesia gives the better defence to corroding agents. An attempt is made in this paper to answer the question, and to set out results which may be of general importance besides.
