PURPOSE: To obtain a glaze capable of emitting light at night for many hours, harmless to human body, having improved weather resistance, heat resistance, corrosion resistance, stain resistance and resistance to change with time, comprising non-lead frit, an inorganic fluorescent substance and a luminous material and a binder and to provide a glazed product.

CONSTITUTION: This glaze, for example, is obtained by blending 100 pts.wt. of non-lead frit comprising 20-40 pts.wt. of SiO2, 26 pts.wt. of B2O3, 6 pts.wt. of K2O, 5 pts.wt. of ZrO3, 5 pts.wt. of BaO, 5 pts.wt. of Zr2O, 3 pts.wt. of Al2O3, 3 pts.wt. of Na2O and 2 pts.wt. of La2O3 not containing Pb and Cb with 3-50 pts.wt. of an inorganic fluorescent substance and a luminous material and 3-60 pts.wt. of a binder for liquefying the non-lead frit. The glaze is applied in a picture pattern to a product to be glazed at a normal temperature and baked at 560-800°C to give the objective glazed product.
