Yintoni eyenza le glasi?

Glass - bento yamandulo yafunyanwa kwaye asetyenziswe ngabantu. Kuye kwafunyaniswa ukuba akukho mntu weza waza wenza iglasi yokuqala. Kungenzeka, wafika kuqala mlilo mlilo kusekho izigidi ezininzi zeminyaka eyadlulayo. Le nto ke ngoku ebizwa obsidian.

Abantu ngokuthe ngcembe ukufunda ngemvelo, sabona ukuba xa mix nesoda yokubhaka ngesanti nobushushu bendalo bungene, iyeza crystalline ibonakala. Ngoko ke uyazi yintoni na kule glasi. Ubuncinane, yiloo nto le nkqubo ichazwe nguPliny lexicographer Greek. Yaye ibali ukusetyenziswa kwabantu le mveliso, nto leyo iye kakhulu sele ubomi uluntu namhlanje.

Kodwa ke kukho enye imfundiso echaza, yintoni eyenza kweglasi. Ezinye izazinzulu zikholelwa ukuba izinto yiglasi wavela eceleni ngexesha zokudubula zomdongwe okanye ubhedu kunyityilikiswa.

Le mveliso ephawulekayo ludlale indima ebalulekileyo kubomi babantu. Zazi ixabiso layo akunakwenzeka. Ukulungiswa iglasi onokuthelekiswa ezifunyaniswe loo mntu njengoko ngokuqulunqa ivili kunye nokuveliswa lomlilo. Naxa eYiputa yamandulo ukwimo wavelisa iindidi izacholo, glaze kubo, ngoko ndafunda ukuba izikhongozeli ukugcina ulwelo ezahlukeneyo.

Ekubeni imveliso yeglasi XIII leminyaka liye landa ngendlela emangalisayo. Iziko kwimveliso yayo yaba Venice. Masters esi sixeko wakwazi ukufunda izinto ezifihlakeleyo yemveliso zeglasi Eastern, kwaye amagosa eziqulunqile kwaphucula ubugcisa indalo yayo. Glassmakers bakwazi ukufikelela elubala iglasi, ngenxa ukongeza iindidi ezingcolisa, baye bafunda ukuba ukwenza oko ukususela ezahlukeneyo izitya, linyuke eziphambili ngokungangqalanga. Kubiza imali eninzi. Ngokubanzi, ukuba imveliso uthatyathwe kuwo asetyenziswa kakhulu ezifana izacholo ebekade impahla, imisebenzi yezandla. Ngexesha le misebenzi inkosi glassblowers yaseVenice Ndihlawule inkululeko yakhe, amabanjwa kwi kwisiqithi okuhlola, bafunda indlela yokwenza iimveliso ezinjalo, ukuba kuzukiswe kwiglasi okuhlola sinwenwile kwihlabathi jikelele.

Lahamba ixesha, yaye abantu bafumane le mveliso kwisicelo umhlobo a. technology mveliso yeglasi eziphuculweyo. Elaligqume icala imveliso maleko iingcinga, amalgam, eza kunye esipilini. Glass iye yasetyenziswa xa kusakhiwa, ingakumbi ukusekwa iitempile kunye amabhotwe. Funda ukwenza umbala iglasi, inkosi waqalisa ukwenza ubuhle ngokuphawulekayo zeglasi nebala kunye neefestile. Ekuhambeni kwexesha, iglasi yayisetyenziswa kwinzululwazi. Abantu baye bafunda ukuba zimke uze ugqalise ukukhanya - owavela khulu, ukwenza neemicroscope kunye kweteleskopu. Ezi izinto ziye zenza linyathelo elikhulu kuphuhliso iinzululwazi zendalo - biology, ngeenkwenkwezi, inzululwazi, kunye namayeza. Ngaphandle koku, le mveliso umsebenzi lwenzululwazi ayinakwenzeka ngokupheleleyo ngokwenza kuyo nayiphi inkalo zenzululwazi.

Yintoni iglasi? Njengoko kumaxesha angaphambili, ukuba yenziwe ukusuka ngesanti. Isibakala sokuba kwentlabathi ibandakanya ubukhulu becala of dust ekhoyo kulo crystals zwi. Itshiswa linyibilike. Ukuba lupholisiwe ngokukhawuleza, i izimbiwa abanaxesha ukwenza ziikristale, nto leyo ebenza ngaphaya. Ukuba ufuna imveliso uba umbala, yongeza ezahlukahlukeneyo oxides yesinyithi. Yintoni eyenza eglasini ukwenzela ukuba kube selubala kangangoko kunokwenzeka? Ukuze wenze oku, isanti ecocekileyo kangangokuba waphants ngaphandle zwi.

Namhlanje kukho iindlela ezininzi processing, emva koko imveliso efunyenwe iipropati ezahlukeneyo ukusuka linyanzelisa kwaye vehicles bulali ngaphambi esipilini. Yintoni eyenza iglasi namhlanje? Isiseko iyafana - zibe elula. Yaye Kuyakhuthaza ukuba isibakala le nto eyenza iglasi kwi uMhlaba - inani elikhulu, yaye asikho engozini lokutshabalala yale kobutyebi bendalo ngokuhamba kwexesha.
