DETERMINATION OF THE ALKALIS IN VITREOUS ENAMEL 1
View through CrossRef
ABSTRACT
Sodium and potassium comprise from 5 to 25%, of the total composition of vitreous enamels. The other 75% is comprised of a wider variety of other elements than is found usually in materials which are analyzed for their alkali content. No less than twentyfive oxides are used commonly in enamel glass, and often fifteen of these are in a single enamel.
The task of removing all interfering elements from the alkalis is an analytical problem of more than ordinary difficulty. The process is necessarily long and tedious. It calls for the most exact attention to detail and the most careful manipulation.
This article tells of attempts to use the usual methods for determination of alkalis in vitreous enamel, and also the procedures found to be most useful and accurate for all classes of enamels.
