Empilweni yansuku zonke, izinkomishi zengilazi ze-borosilicate zivame ukusetshenziselwa ukwenza itiye nekhofi ngenxa yokubonakala kwazo okuphezulu kanye nokuzinza okuhle kwamakhemikhali. Ukushisa kwazo okuphezulu kokumelana kuyinkinga enkulu kubasebenzisi. Izinga lokushisa eliphakeme elisheshayo inkomishi yengilazi ye-borosilicate engakwazi ukumelana nayo cishe ingu-150℃, kuyilapho izinga lokushisa-elide lokusebenzisa eliphephile lingaphansi kuka-120℃. Lesi sici sisukela ekubunjweni kwayo okuyingqayizivele kanye nenqubo yokukhiqiza.
Ukumelana nezinga lokushisa kwengilazi ye-borosilicate kunqunywa ukwakheka kwayo kwamakhemikhali. Isebenzisa i-silicon dioxide njengento esetshenziswayo eyinhloko, ene-10%-15% ye-boron anhydride engeziwe njenge-flux. Uma kuqhathaniswa ne-soda evamile-ingilazi ye-lime, ukungezwa kwe-boron kuvuselela ukwakheka kwamangqamuzana engilazi, kudala ukwakheka kwenethiwekhi okuzinzile. Lesi sakhiwo asinciphisi nje kuphela i-coefficient yengilazi yokwanda okushisayo, sithuthukisa kakhulu ukuzinza kwayo kokushisa, kodwa futhi sithuthukisa ukumelana kwayo nokushisa okuphezulu, okusivumela ukuba sigcine ukuqina kwesimo saso phezu kwebanga lokushisa elibanzi futhi kuvimbele ukuphuka ngenxa yezinguquko ezingazelelwe zokushisa noma ukuchayeka isikhathi eside emazingeni okushisa aphezulu.
Kubalulekile ukucacisa ukuthi izinga lokushisa eliphakeme elingu-150℃akuwona umkhawulo ophelele; ukumelana nokushisa kwangempela kuthinteka izici ezihlukahlukene. Okokuqala, inqubo yokukhiqiza ibalulekile. Ingilazi-yekhwalithi ephezulu ye-borosilicate idlula{4}}izinga lokushisa eliphezulu, idedele ngokugcwele ingcindezi yangaphakathi futhi ilethe ukumelana kwayo nezinga lokushisa eduze nenani lethiyori. Ngokuphambene nalokho, imikhiqizo ekhiqizwa kabi ingase ibe nemifantu efihlekile, okwenza kube lula ukuphuka emazingeni okushisa aphezulu. Okwesibili, izinga lokushisa libalulekile. Nakuba ingilazi ye-borosilicate inokumelana nokushaqeka okuhle kokushisayo, ukuchayeka ngokushesha emazingeni okushisa angaphezu kuka-150℃(njengokuthela emanzini abilayo) kusengawenza aphahlazeke ngenxa yomehluko owedlulele wasendaweni, ikakhulukazi kumamodeli{9}}abiyelwe ngezindonga.
Ekusetshenzisweni kwansuku zonke, izindlela ezifanele zibalulekile ukunciphisa izingozi. Kunconywa ukushisa inkomishi ngamanzi amancane afudumele ngaphambi kokwengeza amanzi abilayo ukuze ugweme ukushintsha okungazelelwe kwezinga lokushisa. Ungabeki inkomishi engenalutho ngokuqondile elangabi elivuliwe noma{2}}idivayisi yokushisisa izinga lokushisa eliphezulu. Ngisho nezinkomishi{4}ezikwazi ukumelana nokushisa zingahlushwa ukushisa okweqile kwendawo kanye nokulimala kwesakhiwo sengilazi uma iyekwa yomile isikhathi eside. Ngaphezu kwalokho, ezinkomishini zengilazi ze-borosilicate ezinezibambo, izindandatho zokuvala, noma ezinye izisetshenziswa, izinto zalezi zinsiza kungenzeka zingakwazi ukumelana nokushisa{6}}. Izinga lokushisa eliphelele lokusetshenziswa kufanele linqunywe ngokusekelwe ekubekezeleleni kwalezi zinsiza, ngokuvamile akumele lidlule i-100 degree.
Uma kuqhathaniswa nengilazi evamile, ingilazi ephezulu ye-borosilicate inenzuzo enkulu-ekumelana nezinga lokushisa eliphezulu. I-soda evamile-ingilazi ye-lime ingakwazi ukumelana namazinga okushisa afinyelela cishe ku-80℃futhi inokumelana nokushaqeka okushisayo, kuyilapho ingilazi ye-borosilicate ephezulu ingamelana nezinga lokushisa elisheshayo elingu-150℃futhi inokumelana nokushaqeka okuhle kwe-thermal, okuyenza ifanelekele izimo eziningi zesiphuzo esishisayo sansuku zonke. Ngesikhathi esifanayo, ukuzinza kwayo kwamakhemikhali okuhle kakhulu kusho ukuthi ngeke kukhiphe izinto eziyingozi emazingeni okushisa aphezulu, kuqinisekiswe ukuphepha okukhulu, okuyisizathu esibalulekile sokusetshenziswa kwayo kabanzi embonini yeziqukathi zokudla.
