Abstract : There is no method of analysis that is specific for calcium carbonate in paint pigments and all quantitative methods are relatively tedious and time-consuming. A simple, volumetric technique is described in which the carbonate is titrated with normal acid after reaction with lithium fluoride. There is no interference from any of the other paint pigments, except the chromates. (Author)
