Imbonakalo yeemveliso zeglasi inokulandwa emva eMesopotamiya kwiminyaka eyi-3,600 eyadlulayo, kodwa abanye abantu bathi isenokuba yimveliso yeglasi yaseYiputa.Obunye ubungqina bezinto zakudala bubonisa ukuba imveliso yokuqala yeglasi yokwenyani yavela kumantla eSiriya yanamhlanje.Imimandla eselunxwemeni, elawulwa ngamaMesopotamiya okanye amaJiphuthaImveliso yeglasi yokuqala yayingamaso eglasi avela phakathi kwinkulungwane yesibini yeXesha Eliqhelekileyo, ekusenokwenzeka ukuba yenzeke ngengozi imveliso yokucutshungulwa kwesinyithi ekuqaleni, okanye izinto zeglasi ezenziwe ngeenkqubo ezifanayo xa kusenziwa imveliso yentsimbi. izinto zodongwe ezipeyintiweyo.

Emva kokubonakala kweemveliso zeglasi, ibe yinto yokunethezeka.Ukuza kuthi ga kwiBronze Age, ukusetyenziswa kweglasi kwangaphambili ngabantu yayikukuyinyibilikisa ukuhombisa ivazi.

Amalungu aphambili eglasi eqhelekileyo yi-silicon dioxide, i-sodium carbonate kunye ne-calcium carbonate.Uninzi lweglasi lunyibilika kwi-1400-1600 degrees Fahrenheit.Ngophuhliso olukhawulezayo lwenzululwazi kunye noluntu lwethekhnoloji, ubugcisa beglasi, njengendlela ekhethekileyo yobugcisa, ikwanika ubomi babantu kunye noyilo lobuGcisa luzise utshintsho oluguqukayo.

Ekudaleni ubucwebe bexesha langoku, iglasi nayo yenye yezinto ezibalulekileyo.Iimpawu ezikhethekileyo zezinto zeglasi zinika umsebenzi iimvakalelo ezimangalisayo.Iyabonakala, iethe-ethe, iqinile, kwaye inemibalabala.Kubonakala ngathi kuqhelekile kwaye kufana nehlabathi elikude.Inokubakho njengebhola encinci yeglasi, kwaye inokuthwalwa njengesakhiwo esihle.Ngaba wakha wabamba iliso leglasi nkqi ebuntwaneni bakho ukubonisa loo nkangeleko yolonwabo nexabisekileyo?
