1. Ukungunda okuqengqelekayo: Indlela eqhelekileyo yokuqengqeleka kokungunda kukucofa umgubo weglasi kwimethi yeglasi. Phambi kokuba kuqengqeleke umbhobho wentsimbi yomthungo othe tye, imathi yeglasi ibotshelelwe phakathi kwentsimbi kunye nombindi wokungunda, ukwenza ipadi yeglasi embindini. Ngaphantsi komphumo wokungqubuzana, umphumo wokuthomalalisa udlalwa ngokufanelekileyo, kwaye imilo yeglasi eyenziweyo ihambelana nesimo se-inlet cone ye-mold rolling kunye nokuphela kwentsimbi.

2. Igubu eliqengqelekayo kunye ne-mandrel: Ukwakhiwa kweglasi esetyenziselwa ukusetyenziswa ngokugudileyo kwegubu eliqengqelekayo kunye ne-mandrel ngumgubo, kunye namasuntswana amancinci kunye nokuthamba okuphezulu, kwaye emva koko ifakwe kumngxuma ongaphakathi kunye nomphandle wangaphandle wentsimbi. Kwakhona, kunokwenzeka ukugubungela ilaphu leglasi kwindawo yangaphandle yezinto zetsimbi kunye nomoya wengubo yeglasi kwintonga engundoqo.

3. Ukususwa kwefilimu yeglasi kumphezulu wangaphandle weumbhobho wentsimbi: Ekubeni i-agent ye-glass smoothing isetyenziswe xa iguqa, ifilimu yeglasi encinci iya kugcinwa ngaphakathi nangaphandle kombhobho wensimbi. Le filimu ifana neglasi eqhelekileyo, ilukhuni kwaye inzima. I-Crisp, echaphazela imveliso emva kokusetyenziswa, ngoko kufuneka isuswe. Kukho iindlela zoomatshini kunye neekhemikhali zokususa. Indlela yomatshini ingasetyenziselwa ukuchama, ukupholisa amanzi kunye nokwelula kunye nokolula. Ukuba sisebenzisa iindlela zeekhemikhali ukususa ifilimu yeglasi, sonke siyazi ukuba iimpawu zeekhemikhali zeglasi zizinzile ngokufanelekileyo. Ngoko ke, ukuba sisebenzisa imichiza, sisebenzisa iiasidi ezinamandla okanye ulwelo oluqinileyo lwealkaline. Nangona kunjalo, umonakalo wendlela ye-pickling kukuba i-corrosive kakhulu kwimibhobho yensimbi eyahlukeneyo yezinto eziluhlaza, ezinokubangela ukuba umphezulu wombhobho wentsimbi uvuthwe, ngakumbi kwi-carbon steel. Akunandleko kwaye akufanelekanga ukukhetha ukukha yedwa. Ke namhlanje, indlela yokususa iasidi kunye nealkali isetyenziswa kakhulu.
