Ingilazi ephezulu ye-borosilicate inezinzuzo eziningi ezibalulekile. I-Coefffion yayo ephakeme kakhulu ivumela ingilazi ukuthi iqhubeke isizinzile noma ezindaweni ezinokungafani okushisa kakhulu. Isibonelo, ingilazi ngeke iphule noma igcwaliswa ngokushesha ngamanzi ashisayo ngemuva kokukhishwa efrijini. Lolu hlobo lomkhiqizo wengilazi lungakwazi ukubhekana kalula namazinga okushisa asukela ku--20 degrees kuya kuma-degree ayi-130. Noma ngabe kuyingilazi eyodwa noma i-microwave ye-microwave, ingasetshenziswa ngqo ngaphandle kokukhathazeka ngokuphuka.
Ngaphezu kwalokho, ukumelana kwamanzi kanye nokuphikiswa kwe-acid kwe-borosilung glass ephakeme kufinyelela ezingeni 1, ukumelana kwe-alkali kuyizinga, futhi okuqukethwe yizakhi eziyingozi kungaphansi kwe-0,1%, okwenza kube yisinqumo esihle samanzi okuphuza aphephile. Yize iningi lezingilazi ezivinjelwe ukushisa zisetshenziswa kabanzi emakethe zithi zenziwe nge-borosilile ephezulu, ikhwalithi yangempela ingahluka, futhi abathengi badinga ukuqaphela lapho bekhetha.
