Zvinhu zvegirazi zvinonyanya silicon dioxide.Magirazi akajairika icalcium silicon girazi.Izvo zviri nani ndeye borosilica yakakwirira, iyo inonzi inonzi hard glass.
Ordinary wide-mouth glass is calcium silicon glass.Kuti ndikuyeuchidze, izvo zvinotungamira zvatinowanzo kunetseka nezvazvo zviri pano.Nekuda kweiyo yakachipa calcium silicon girazi, mutengo wekugadzira wakaderera, yepakati lead yemukati haigone kushanda.nguva imwe.
Mamwe magirazi epamusoro-soro ane borosilica yakakwirira.Iyo yakakwirira borosilicon inenge isingabudiriri, uye mhizha inonyanya kuoma, saka inodhura zvikuru.
