Abstract: Encapsulation pigments comprising chromophoric particles embedded in glaze-stable casings are prepared by means of calcination from the appropriate initial products. High yields and strong color intensities are obtained if the chromophoric substance or its initial compounds are bound in and/or to a zeolite and are calcined in this form with the remaining constituents.

Abstract: There are described luminescent materials activated with lead upon excitation with long wave and short wave ultraviolet rays emit in the blue-green region, have long afterglow times, can be prepared from components which do not have high purity, are not susceptible to pulverizing, and are stable to the customary ceramic glazes. They consist of (or consist essentially of): 10 to 89.9 mole % zirconium oxide (ZrO2) 5 to 85 mole % boron oxide (B2O3) 5 to 85 mole % silicon dioxide (SiO2) 0.1 to 20 mole % lead oxide (PbO) 0 to 15 mole % sodium oxide (Na2O) 0 to 15 mole % potassium oxide (K2O) and 0 to 5 mole % aluminum oxide (Al2O3).
