the specific process of forming the octahedral holes on the primer in the third step is as follows: in the process of applying the primer to the green bricks, an octahedral drill bit is arranged at the bottom of an upper die, a lower die fixes the green brick layer, glazing is carried out on the surface of the green brick layer, the primer layer is dried at a certain temperature, and then the combination of the green brick layer and the primer layer is separated from the upper die, so that octahedral holes are formed on the primer;
the first step further comprises the step of polishing the obtained dry gold star glass particles after the crushing and screening step;
the bottoms of the octahedral holes are arranged in a cone shape, the bottoms of the golden star glass dry particles extend into the octahedral holes, and the openings of the octahedral holes are arranged to be narrow at the bottom and wide at the top;
the chemical mass composition of the golden star glass dry particles in the first step is as follows: siO2: 50-70%, al2O3: 0.1-10%, K2O:0.1 to 5 percent of Na2O:0.1 to 10 percent of CaO: 5-25% of MgO: 0.1-10%, cr2O3: 0-8%, 30-2% of Co2O, fe2O3: 0-8%, mnO2: 0-3%, P2O5: 0-5%, total impurity not more than 2%; or the mass composition of the raw materials is as follows: 20-40 parts of quartz sand and potassium sodium feldspar: 15-50 parts of calcite: 10-30 parts of dolomite, 1-20 parts of aluminum oxide: 0 to 5 parts of coloring agent containing at least one of Cr2O3, co2O3, fe2O3 and MnO2 in 1 to 10 parts;
the specific preparation method of the golden star glass dry particles in the first step comprises the following steps: after uniformly mixing the raw materials of the golden star glass, melting the raw materials into glass in a glass melting kiln at 1350-1600 ℃, directly flowing glass liquid into water to quench the glass liquid into a frit, and drying, crushing and screening the frit into 20-150 meshes to form golden star glass dry particles;
the specific steps of conveying to a roller kiln for firing in the sixth step are as follows:
(1) The green bricks coated with the ground glaze and the gold star glass dry particles are sent into a drying kiln for drying, and the temperature in the drying kiln is 100-110 ℃;
(2) Preheating in a preheating furnace at the preheating temperature of 400-450 ℃ for 20min;
(3) Then sintering in kiln at 1190-1210 deg.c for 70-75min, and polishing.
