Variation of the particle size of the precipitated titanium dioxide with its change in concentration was indicated by reflectance data and substantiated by electron micrographs of these precipitated crystals. Possible correlation of the data with the precipitation laws of von Weimarn is discussed. Two methods were used for obtaining particle‐size data: the first was by the study of shadowed replicas of etched enamel disk surfaces, and the second and more important, by the study of TiO 2 crystals removed from an enamel by selective solution with hydrofluoric acid.
