Kwipakethe yentengiso, ukwenziwa ngokwezifiso kwekhaya, kunye nentengiso enegama, iingqayi zeglasi ezinemigca zibe lukhetho oluphezulu kwiimveliso ezininzi kunye nabantu ngabanye ngenxa yobume bazo obukhethekileyo kunye nokuthungwa. Uyilo olulungiselelweyo alukwazi ukuhlangabezana neemfuno ezithile kuphela kodwa lukwadlulisela nobuntu bohlobo. Nangona kunjalo, ukwenziwa kweglasi yeglasi ngokwezifiso kubandakanya izinto ezininzi ezinjengobugcisa, izixhobo kunye neenkcukacha. Ukuba imiba ephambili ayihoywa, iingxaki ezifana nemveliso egqityiweyo ingafikeleli kulindelo okanye ukusilela ukusebenza zinokwenzeka lula.
Okokuqala, ukucacisa ngokucacileyo iimfuno zokwenza ngokwezifiso kunye nemeko yokusetyenziswa ekujoliswe kuyo kubalulekile. Ngaphambi kokwenza ngokwezifiso, injongo yeengqayi zeglasi kufuneka icaciswe ngokucacileyo: kukugcinwa kokutya, ukupakishwa kwezithambiso, ukuhombisa ikhaya, okanye njengesipho? Iimeko ezohlukeneyo zineemfuno ezahlukileyo kakhulu: ukutya -usetyenziso lwebakala kufuneka lubambelele ngokungqongqo kwimigangatho yeglasi yoqhagamshelwano lokutya ukuqinisekisa ukuba akukho zinto ziyingozi ziphumayo; ukwenza isipho ngokwezifiso kufuna ingqalelo kwiinkcukacha zenkangeleko kunye nokuthungwa, ngoyilo olunemigca kunye nobungakanani bobungakanani obuhambelana nethoni yesipho. Kwangaxeshanye, ubungakanani, iinkcukacha (ububanzi, ubude, umthamo), kunye nokuba izincedisi ezifana neziciko kunye neelebhile ziyafuneka kufuneka zichazwe ngokucacileyo ukuphepha ukuguqulwa okuphindaphindiweyo ngenxa yeemfuno ezingaqondakaliyo, ixesha elikhulayo kunye neendleko.
Okwesibini, ukhetho lwezinto eziphathekayo lungundoqo wokwenza ngokwezifiso, ukugqiba ngokuthe ngqo umgangatho wemveliso kunye nokhuseleko. Kwiingqayi zeglasi ezinemigca, iglasi ephezulu yeborosilicate yeyona nto ikhethwayo, njengoko iyakwazi ubushushu-iyakwazi ukumelana nobushushu, iyakwazi ukubola{2}}iyaxhathisa, icace kakhulu, kwaye ayiqhekeki lula, iyenza ilungele ukusetyenziswa ixesha elide{3}. Lumkela abavelisi abasebenzisa iglasi eqhelekileyo njengebambela; Iglasi eqhelekileyo inokukhanya okuphantsi kunye nokuqina okulambathayo, okukhokelela ngokulula kwimigca emfiliba kunye nokuqhekeka kwejagi. Ngaphaya koko, ukuba ingqayi yenzelwe iimeko zobushushu obuphezulu-(ezifana namanzi ashushu okanye ukufudumeza i-microwave), umenzi kufuneka aziswe ngokucacileyo ukuba akhethe imathiriyeli yeglasi enyangwe ngeenkqubo zokumelana nobushushu obuphezulu{7}ukunqanda iingozi zokhuseleko ngexesha lokusetyenziswa.
Uyilo lwemigca kunye neenkcukacha zobugcisa ngumphefumlo wokwenza ngokwezifiso, ofuna ukulingana phakathi kobuhle kunye nokusebenza. Isimbo (imigca ethe tye, imigca ediagonal, imigca ejikajikayo), ubukhulu, kunye nesithuba semigca engqukuva kufuneka siyilwe ngokuqiqileyo kunye nokumila kwejagi ukuphepha imigca exineneyo ngokugqithisileyo ebangela ukuba ingqayi ibonakale inamafu, okanye imigca egqagqene kakhulu echaphazela imbonakalo. Ngelo xesha, ingqalelo kufuneka ihlawulwe ukuhambelana kwemivimbo. Xa ulungiselela iimveliso zebhetshi, iisampulu kufuneka zicelwe kumvelisi ukuze kuqinisekiswe ukuba indlela yomgca kunye nobukhulu bengqayi nganye yeglasi iyafana, ngaphandle kokulungelelaniswa, ukwaphuka, okanye ezinye iziphene. Ngaphaya koko, ukusetyenzwa kwemigca kwahlulwe ngokwemigca yangaphakathi nangaphandle. Imivimbo yangaphakathi kulula ukuyicoca kwaye iyancipha ukuqokelelwa kokungcola, ngelixa imivimbo yangaphandle inempembelelo ebonakalayo enamandla; inkqubo efanelekileyo inokukhethwa ngokusekelwe kusetyenziso olujoliswe kuyo.
Ngaphaya koko, ukuchaneka komda kunye nokusebenza kokutywinwa kubalulekile. Kwiingqayi zeglasi ze-conical, ukuchaneka kobubanzi, ukuphakama, kunye ne-taper kuchaphazela ngokuthe ngqo ukulungelelaniswa kwesiciko kunye ne-aesthetics jikelele. Ukutenxa ngokugqithisileyo kwe-dimensional kunokuthintela isiciko ekutywinweni ngokufanelekileyo, kube nefuthe ekusebenzeni kogcino. Xa uhlengahlengisa, uluhlu lonyamezelo lwedimensional kufuneka lucaciswe ngokucacileyo, kwaye umenzi kufuneka anike ingxelo yokuhlola idimensional ukuqinisekisa imilinganiselo efanayo kwiibhetshi. Kwizicelo ezifuna ukutywinwa okungangeni moya (okufana nokugcinwa kokutya), iminqwazi yokutywina efanelekileyo (iglasi, i-silicone, okanye isinyithi) kufuneka ikhethwe, kwaye umsebenzi wabo wokutywina uvavanywe ukuthintela ukuvuza kunye neminye imiba.
