Kungani itshe legwadle liqine kangaka futhi lihlala isikhathi eside?
Igwadleingenye yamatshe aqine kakhulu edwaleni. Ayiqinile nje kuphela, kodwa ayincibiliki kalula ngamanzi. Akunakwenzeka ukuguguleka nge-asidi ne-alkali. Ingakwazi ukumelana nengcindezi engaphezu kuka-2000 kg ngesentimitha yesikwele. Isimo sezulu asinawo umthelela osobala kuso amashumi eminyaka.

Ukubukeka kwegwadle kusekuhle impela, kuvame ukuvelamnyama, mhlophe, impunga, ophuzi, umbala wembali, i-rose nokunye umbala ongajulile, hlanganisa indawo emnyama, enhle futhi ephanayo. Izinzuzo ezingenhla, iba yisinqumo esiphezulu etsheni lokwakha. Itshe lenhliziyo letshe lesikhumbuzo lamaqhawe abantu esigcawini sase-Beijing se-tiananmen lenziwe ngocezu lwegwadle eliye lathunyelwa lisuka e-laoshan, esifundazweni sase-shandong.

Kungani i-granite inalezi zici?
Ake sihlole izithako zayo kuqala. Ezinhlayiyeni zamaminerali ezakha i-granite, ngaphezu kwe-90% ngamaminerali amabili, i-feldspar ne-quartz, okuyi-feldspar kakhulu. I-Feldspar ivame ukuba mhlophe, impunga, ibomvu, futhi i-quartz ayinambala noma impunga, okwenza ama-hues ayisisekelo egwadle. I-Feldspar ne-quartz zingamaminerali aqinile futhi kunzima ukuhamba ngemimese yensimbi. Ngokuqondene namabala amnyama ku-granite, ikakhulukazi ama-mica amnyama namanye amaminerali. Nakuba i-black mica ithambile, ayibuthakathaka ekumelana nokucindezela, futhi izingxenye zayo ku-granite zincane kakhulu, ngokuvamile zingaphansi kuka-10%. Lesi yisimo esiqinile kakhulu se-granite.
Esinye isizathu esenza ukuthi i-granite ibe namandla ukuthi izinhlamvu zayo zamaminerali ziboshwe ngokuqinile komunye nomunye, nokuthi izimbotshana zivame ukubala ngaphansi kwe-1% yenani eliphelele ledwala. Lokhu kunikeza i-granite ikhono lokumelana nokucindezela okunamandla futhi ayingenwa kalula ngamanzi.

I-Granite nakuba inamandla ikakhulukazi, kodwa esikhathini eside sokukhanya kwelanga, umoya, amanzi kanye ne-biology, kuyoba nosuku "lokubola", ungakukholelwa? Iningi lesihlabathi emfuleni yizinhlamvu ze-quartz ezishiywe ngemuva kokubhujiswa, futhi ubumba olusakazwa kabanzi luwumkhiqizo wesimo sezulu se-granite. Kodwa kuzoba isikhathi eside, eside, ngakho-ke ngokwesikhathi somuntu, igwadle liqine kakhulu.
