Ngenxa yokuwohloka kanzima, iplastiki iba yeyona nto ingcolisekileyo.Ukuba ufuna iplastiki ibe kukuwohloka kwendalo kwindalo, kufuneka malunga ne-200 ~ 1000 iminyaka.Kodwa enye imathiriyeli ibambelele ngakumbi kuneplastiki, kwaye ikhona ixesha elide, yiglasi.
Kwiminyaka engama-4000 eyadlulayo, umntu wayekwazi ukwenza iglasi.Kwaye malunga neminyaka engama-3000 eyadlulayo, amaJiphutha amandulo ayenobuchule kubuchule bokuvuthela iglasi.Ngoku ezininzi iimveliso zeglasi ngamaxesha ahlukeneyo zifunyenwe yi-archeologist, kwaye zigcinwe kakuhle, oku kubonise ukuba iminyaka eyikhulu ayinayo impembelelo kwiglasi.Ukuba ixesha elide, uba yintoni umphumo?
Isithako esiphambili seglasi yi-silica kunye nezinye i-oxides, ayinayo i-crystal eqinile kunye nesakhiwo esingaqhelekanga.
Ngokuqhelekileyo, ulungelelwaniso lwemolekyuli yolwelo negesi alulungelelananga, yaye xa luqinileyo lunocwangco.iglasi yomelele, kodwa ilungiselelo lemolekyuli lifana nolwelo kunye negesi.Ngoba?Ngapha koko, ulungiselelo lweathom yeglasi alunacwangco, kodwa ukuba kujongwa iathom nganye nganye, yiathom enye yesilicon edibanisa neeathom ezine zeoksijini.Eli lungiselelo likhethekileyo libizwa ngokuba "yi-short range order".Yiyo loo nto iglasi yomelele kodwa ibuthathaka.
Eli lungiselelo likhethekileyo lenza iglasi ngobulukhuni obukhulu, kwangaxeshanye, ipropathi yemichiza yeglasi izinzile, phantse akukho mpendulo yeekhemikhali phakathi kweglasi kunye nezinye izinto.Ngoko ke kunzima ukuba i-corrod kwiglasi kwihlabathi lendalo.
Iglasi enkulu yayiza kuqhekeka ibe ziziqwenga ezincinci phantsi kohlaselo, ngohlaselo olongezelelweyo, amaqhekeza amancinci aya kuba mancinci, abe mancinci kunesanti.Kodwa iseyiglasi, iglasi yayo yangaphakathi ayizukutshintsha.
Ngoko iglasi inokubakho kwihlabathi lendalo ngaphezu kwamawaka eminyaka.
