1. Ubuhlalu bengilazi bobabili buthambile futhi benziwe kanzima ngezinto ezisezingeni eliphakeme, okungukuthi, bunamandla athile omshini, okuqukethwe kwe-sio2 kukhulu noma kulingana no-68%, ubulukhuni bungafinyelela ku-6-7 Mohs, futhi zivumelana nezimo ngokwanele ukuba zisetshenziswe ngokuphindaphindiwe. Akulula ukuphuka, idivayisi efafaziwe inomphumela ofanayo, futhi impilo yesevisi ingaphezu kwezikhathi ezi-3 ubude kunobuhlalu obujwayelekile bezingilazi.
2. Ukufana okuhle-izinga lokuzungeza likhulu noma lilingana no-80%, futhi usayizi wezinhlayiyana ufana. Ngemva kokufafaza, i-coefficient yokukhanya yedivayisi ye-sandblasting igcinwa iyunifomu, futhi akulula ukushiya ama-watermark.
3. Ubuhlalu bengilazi obucwebezelayo obungabuyiseleki njengokudutshulwa bunezinzuzo ezilandelayo ngaphezu kwanoma iziphi ezinye izinto eziqhumayo: Ngaphandle kwezinto eziabrasive zensimbi, zingahlala isikhathi eside kunanoma iyiphi enye imidiya. Zenziwe ngezinto ezingezona ze-alkaline soda lime glass. Ukuzinza okuhle kwamakhemikhali, ngeke kungcolise insimbi ecutshunguliwe, kungasheshisa ukuhlanza, kuyilapho kugcinwa ukunemba kokucubungula kwento yokuqala.
4. Ubushelelezi futhi obungenakho ukungcolaâukubukeka kuyizinhlayiya eziyindilinga ezingenakho ukungcola; ubuso bushelelezi futhi buba nesiphetho esihle
