Embodiment 1
[0031] (1) According to the mass fraction of 10% SiO 2 , 40% of B 2 o 3 , 6% Al 2 o 3 , 3.8% MgO, 15% Na 2 O, 10% K 2 O, 10% CaO, 5% ZnO, 0.2% Sb 2 o 3 Accurately weigh the raw materials and mix well. Raise the crucible to 900°C at a rate of 5°C / min in a high-temperature lifting furnace, add the raw materials mixed in proportion to the crucible, and keep warm for 3 hours to obtain a high-temperature glass liquid.
[0032] (2) After washing and drying the milky white cullet, crush and sieve, select glass cullets with a diameter of 30 mm and a thickness of 2-3 mm for later use. Lay a layer of ceramic fiber paper on the refractory board, and place a 30mm high baffle around it, and paste ceramic fiber paper on the inside of the baffle as a refractory mold, and then spread the cleaned and dried glass fragments in layers On the refractory mould, the height of the glass shards piled up is 6mm lower than the height of the baffle.

Embodiment 2
[0035] (1) According to the mass fraction of 20% SiO 2 , 40% of B 2 o 3 , 8% Al 2 o 3 , 4% MgO, 8% Na 2 O, 5% K 2 O, 2% CaO, 12.5% ZnO, 0.5% Sb 2 o 3 Accurately weigh the raw materials and mix well. Raise the crucible to 1000°C at a rate of 5°C / min in a high-temperature lifting furnace, add the raw materials mixed in proportion to the corundum crucible, and keep warm for 2.5 hours to obtain a high-temperature glass liquid.
[0036] (2) Wash and dry the emerald green cullet, crush and sieve it, and select glass cullets with a diameter of 40mm and a thickness of 3-5mm for subsequent use. Lay a layer of ceramic fiber paper on the refractory board, and place a 30mm high baffle around it, and paste ceramic fiber paper on the inside of the baffle as a refractory mold, and then spread the cleaned and dried glass fragments in layers On the refractory mould, the height of the glass shards piled up is 8mm lower than the height of the baffle.

Embodiment 3
[0039] (1) According to the mass fraction of 20% SiO 2 , 30% B 2 o 3 , 5% Al 2 o 3 , 2% MgO, 11.6% Na 2 O, 10% K 2 O, 6% CaO, 15% ZnO, 0.4% Sb 2 o 3 Accurately weigh the raw materials and mix well. Raise the crucible to 1100°C at a rate of 5°C / min in a high-temperature lifting furnace, add the raw materials mixed in proportion to the crucible, and keep warm for 3 hours to obtain a high-temperature glass liquid.
[0040] (2) Washing, drying, crushing and sieving the brown cullet, and selecting glass cullets with a diameter of 50mm and a thickness of 5-8mm for later use. Lay a layer of ceramic fiber paper on the mullite refractory board, and place a 30mm high baffle around it, and paste ceramic fiber paper on the inside of the baffle as a refractory mold, and then separate the cleaned and dried glass pieces The layers are tiled on the refractory mold, and the height of the glass shards is 12mm lower than the height of the baffle.
