A Note on a Powder Method of Comparing the Solubilities of Glasses

JSGT 1936 V20 T416-T417

The powder is carefully prepared so as to ensure uniformity of grain size. Comparisons of solubility are made by taking standard quantities of glass and water and adding a standard quantity of a mixture of three indicators. The pH values of the solutions are taken by matching with standard buffer solutions.
