Ma muli o ka paʻakikī paʻakikī, lilo ka plastic i mea haumia nui.Inā makemake ka plastic i ka degradation kūlohelohe i ka honua kūlohelohe, pono ma kahi o 200 ~ 1000 mau makahiki.Akā ʻoi aku ka ikaika o nā mea ʻē aʻe ma mua o ka plastic, a lōʻihi ka lōʻihi, he aniani.
Ma kahi o 4000 makahiki aku nei, hiki i ke kanaka ke hana i ke aniani.A ma kahi o 3000 mau makahiki i hala aku nei, akamai ko ʻAigupita kahiko i ka hana puhi aniani.I kēia manawa, nui nā huahana aniani i nā manawa like ʻole e ʻike ʻia e ka archeologist, a ua mālama maikaʻi ʻia, ua hōʻike ʻia kēia he haneli mau makahiki ʻaʻohe hopena i ke aniani.Inā lōʻihi, he aha ka hopena?
ʻO ka mea nui o ke aniani ʻo ka silica a me nā oxides ʻē aʻe, he paʻa non-crystal me ka hana ʻole.
ʻO ka mea maʻamau, he ʻino ka hoʻonohonoho molekala o ka wai a me ke kinoea, a no ka paʻa, ua hoʻonohonoho ʻia.paʻa ke aniani, akā ʻo ka hoʻonohonoho molekala e like me ka wai a me ke kinoea.No ke aha mai?ʻO ka ʻoiaʻiʻo, ʻaʻohe pilikia ka hoʻonohonoho ʻana o ke aniani, akā inā e nānā paʻa ʻia ka ʻātoma, hoʻokahi ʻātoma silika ia e hoʻopili ʻia me nā ʻātoma oxygen ʻehā.Ua kapa ʻia kēia hoʻonohonoho kūikawā ʻo "ka hoʻonohonoho pōkole".ʻO kēia ke kumu he paʻakikī akā palupalu ke aniani.
ʻO kēia hoʻonohonoho kūikawā e hana i ke aniani me ka paʻakikī nui, i ka manawa like, paʻa loa ka waiwai kemika o ke aniani, aneane ʻaʻohe hopena kemika ma waena o ke aniani a me nā mea ʻē aʻe.No laila paʻakikī ke ʻānai ʻia no ke aniani i ke ao kūlohelohe.
Nahā ke aniani ʻāpana nui i ʻāpana liʻiliʻi ma lalo o ka hoʻouka ʻana, me ka hoʻouka hou ʻana, ʻoi aku ka liʻiliʻi o nā ʻāpana liʻiliʻi, ʻoi aku ka liʻiliʻi ma mua o ke one.He aniani nō naʻe, ʻaʻole e loli kona ʻano aniani.
No laila hiki i ke aniani ke noho ma ke ao kūlohelohe no nā tausani makahiki.
