Making method of super thick and large glass

The invention discloses a making method of super thick and large glass. The glass comprises, by weight, 70-80 parts of silica sands, 20-25 parts of sodium carbonate, 0.2-1 part of mirabilite, 5-10 parts of dolomite, 10-15 parts of limestone and 0.1-1 part of alumina powder. The making method of the glass comprises the steps of 1) burdening, 2) melting, 3) molding, and 4) annealing. The super thick and large glass with good light transmittance and high strength is obtained through improving the raw materials and the technology of the glass. 本发明公开了种超厚超大玻璃的制造方法，其特征在于，所述的玻璃按重量份包括以下组分：硅砂：70-80份；纯碱：20-25份；芒硝：0.2-1份；白云石：5-10份；石灰石：10-15份；氧化铝粉：0.1-1份；该玻璃的制造方法包括以下步骤：1)配料；2)熔化；3)成型；4)退火。本发明通过对玻璃的原料和工艺进行改进，得到透光率好、强度高的超厚超大玻璃。
