Dental glaze composition which was matured at lower 200 ↿F than transition temp. of false tooth's enamel (1400-1600↿F), having 10±4 average particle size and 9-12 × 10-6 /≦̸C thermal expansion coefficient, was developed. Thus, the dental glaze was composed of SiO2 45-52 %, B2O3 15-20 %, Al2O3 10-15 %, K2O 3.5-7.5 %, Na2O 12-17 %, CaO 0-1 %, ZnO 0-1 % and F 1-3 %.
