Uninzi lweemveliso zeglasi ezigqwesileyo ziye zafunyanwa kwiMimandla yaseNtshona ye-China yakudala, ukusukela kwiminyaka engama-2,000 eyadlulayo, kwaye ezona mveliso zindala zeglasi emhlabeni zineminyaka engama-4,000 ubudala.Ngokutsho kwabembi bezinto zakudala, ibhotile yeglasi yeyona nto igcinwe kakuhle ehlabathini, kwaye ayigqwala lula.Iingcali zamachiza zithi iglasi ngudade wesanti, kwaye okoko nje isanti isemhlabeni, iglasi isemhlabeni.
Kungakhathaliseki ukuba ibhotile yeglasi inokugqwala, oko akuthethi ukuba ibhotile yeglasi ayinakoyiswa kwindalo.Nangona ingenako ukutshatyalaliswa ngamachiza, inokuthi "ibhujiswe" ngokwasemzimbeni.Umoya namanzi endalo zezona ntshaba zayo ezinkulu.
EFort Bragg, eKhalifoniya, eUnited States, kukho unxweme olunemibalabala.Xa ungena, unokubona ukuba yenziwe ngeebhola ezimibalabala ezingenakubalwa.Ezi pellets azingomatye kwindalo, kodwa ziibhotile zeglasi ezilahlwa ngabantu.Ngeminyaka yoo-1950, yayisetyenziswa njengendawo yokulahla inkunkuma kwiibhotile zeglasi ezilahliweyo, emva koko indawo yokulahla ivalwa, ishiya amashumi amawaka eebhotile zeglasi ezishiywe ngasemva, kanye emva kweminyaka engama-60, zagudiswa ngamanzi olwandlekazi loLwandlekazi iPasifiki. egudileyo kwaye engqukuva.
Kwiminye iminyaka eyi-100 okanye ngaphezulu, unxweme olunemibala yeglasi yesanti luya kunyamalala, izazinzulu zithi.Ngenxa yokuba amanzi olwandle kunye nempepho yolwandle igudla umphezulu weglasi, ekuhambeni kwexesha, iglasi iyakhunyulwa ibe ngamasuntswana, ize iziswe elwandle ngamanzi olwandle, ize ekugqibeleni izike iye ezantsi elwandle.
Ulwandle olukhazimlayo alusiziseli nje ukuyonwabela okubonakalayo, kodwa lukwakhokelela ekucingeni malunga nendlela yokuhlaziya iimveliso zeglasi.
Ukuze kuthintelwe inkunkuma yeglasi ekungcoliseni okusingqongileyo, sithatha ngokubanzi iindlela zokurisayikilishwa.Njengentsimbi esetyenzisiweyo esetyenzisiweyo, iglasi ephinda isetyenzisiwe ibuyiselwa eziko ukuze inyibilike kwakhona.Ekubeni iglasi ingumxube kwaye ayinayo indawo edibeneyo yokunyibilika, isithando somlilo sibekwe kwii-gradients ezahlukeneyo zeqondo lokushisa, kwaye icandelo ngalinye liya kunyibilikisa iglasi yeengoma ezahlukeneyo kwaye lihlukanise.Endleleni, ukungcola okungafunwayo nako kunokususwa ngokongeza ezinye iikhemikhali.
Ukurisayikilishwa kweemveliso zeglasi kwilizwe lam kuqale kade, kwaye izinga lokusetyenziswa limalunga ne-13%, lisalele emva kumazwe aphuhlileyo eYurophu nase-United States.Amashishini afanelekileyo kula mazwe akhankanywe apha ngasentla sele ekhulile, kwaye iteknoloji yokuphinda isetyenziswe kunye nemigangatho ifanelekile ukuba ibhekisele kwaye ifundwe kwilizwe lam.
