-Umlomo wengilazi uqukethe ingilazi ye-borosilicate ephezulu enezindonga eziwugqinsi 3.3.Lena ingilazi yaselabhorethri eyaziwa ngokumelana namakhemikhali nezinga lokushisa.
-Ukunambitheka kuhlala kuhlanzekile futhi kungangcolisiwe ngenxa yengilazi yezinga eliphezulu yaselabhorethri.Ngakho ungakwazi ukushintsha kalula phakathi kwezinhlobo ezahlukene zikagwayi.
-Ingilazi yethu ye-borosilicate engu-3.3 (ingilazi yaselabhorethri ekwazi ukumelana nokushisa) ayimumbi iphunga, ukunambitheka noma ukushintsha kombala, impahla ibuye ibonakale ukumelana nokushisa futhi ingamelana nokuguquguquka okuqinile kwezinga lokushisa.Futhi iqinile futhi iqinile kakhulu.
-Umlomo wethu ulingana nawo wonke amapayipi abicah ajwayelekile anobubanzi obungaphakathi obufika ku-1.2 cm.
