The invention relates to a manufacturing technique for forming ultrawhite patterned glass, relating to the glass forming manufacturing technique field. The manufacturing technique comprises mixing, forming, annealing and detection cutting. The manufacturing technique is as follows: deferrization is performed on selected compositions; and raw materials after deferrization are mixed by weight portion: 59 to 64 portions of silica sand, 0.5 to 2.5 portions of aluminum hydroxide, 17 to 22 portions of sodium carbonate, 0.2 to 1 portion of anhydrous sodium sulfate, 0.3 to 2 portions of sodium nitrate, 13 to 18 portions of calcium carbonate and 0 to 0.5 portion of antimony trioxide. Under the condition of forming, the temperature of a rolling operation part is between 900 and 1100 DEG C, the rolling speed is between 145 and 220 meters per hour; the annealing temperature is between 60 and 590 DEG C, and the annealing time is between 0.1 and 0.3 hour. By application of the technique, the glass with high transmittance, low iron content, ideal flatness and good impact resistant effect is produced.
