The invention discloses a cyan borosilicate lead-free low-alumina glaze, its preparation, application in the field of architectural decoration, and a corresponding relationship between different colorant contents and L * , a * and b * values in CIE color space. Color prediction/design methods for mathematical models. The cyan borosilicate lead-free low-alumina glass is obtained by mixing the basic ingredients and the colorant uniformly, heating, casting and annealing. The basic batch is composed of the following raw materials by mass percentage: 65.0%-75.0% SiO 2 , 6.0%-12.0% B 2 O 3 , 5.5%-7.0% Na 2 O, 2.0%-4.0% BaO, 2.0%-5.5% CaO, 0-2.5% SrO, 1.0%-1.5% K 2 O, 1.0%-2.5% ZnO, 1.0%-2.0% Al 2 O 3 , 2.0%-5.5% MgO, 0.05%-0.15% Li 2 O, 0.05%-0.2% TiO 2 , 0-0.15% Fe 2 O 3 . The colorants are 0.3%-1.3% CeO 2 and 0.004%-0.008% Co 2 O 3 based on the total mass of the base batch as 100%. |
