The standard (CSN 70 8001) was proposed and approved for classification, examination and marking of crystal household glasses. Methods for PbO, BaO, and ZnO determination, are critically examined and a procedure of electrolytic, gravimetric, and chromatographic separation as well as determination of the oxides given is proposed. Both methods are reciprocally compared, based on model experiment results and by repeated determination of PbO, BaO and ZnO in a special crystal glass.
