The invention relates to a bottle body processing technology of a gas absorption bottle. The bottle body processing technology comprises: (1) placing a soft sodium alkali chemical glass material, quartz sand, boric acid and magnesium fluoride into a stirrer, and mixing uniformly; (2) pouring the mixture into a high temperature kiln, heating to a temperature of 1280 DEGC, firing for 3-5 h, coolingto a temperature of 680 DEGC at 6 DEG C/min, and carrying out thermal insulation; (3) adding chromium oxide, heating to a temperature of 1580 DEG C at 15 DEG C/min, and carrying out thermal insulationfor 2-4 h; (4) feeding the material obtained in the step (3) into a molding machine, preparing a bottle body according to a certain specification, and naturally cooling; and (5) spraying the bottle body. The finished product of the invention has characteristics of high transparency, heat resistance and long service life.
