1. Raw khoom crushing: crushing silica xuab zeb (sandstone), soda tshauv, feldspar, dolomite, limestone thiab mirabilite rau hauv hmoov.
2. Qhov hnyav: hnyav ib yam ntawm cov hmoov sib txawv raws li daim ntawv teev npe batching.
3. Sib tov: sib tov thiab do cov hmoov nplej uas hnyav rau hauv kev sib tov.
4. Melting: pub cov batch rau hauv lub khob rauv thiab yaj mus rau hauv cov kua iav ntawm 1700 degree.
5. Kev sib sau ua ke: cov kua iav raug xa mus rau tin da dej (float method), lub tshuab nqus tsev tiaj tus (daim phiaj txoj kev), Calender (txoj kev calendering, ntxiv cov hlau hlau yog hlau iav) thiab tsim rau hauv iav ca.
6. Annealing: xa cov khoom iav tsim rau lub qhov cub annealing rau annealing, sib npaug ntawm kev ntxhov siab thiab tiv thaiv nws tus kheej tawg thiab nws tus kheej tawg.
