Izindandatho Zokuthembisana Ezingcono Kakhulu ezingama-23 zeSapphire
Uma uwuhlobo lukamakoti ofuna ukwephula isiko ngendandatho yakho yokuthembisana umshado, indandatho yomshado yesafire iyindlela emangalisayo yokwenza kanjalo. Kwaduma uPrincess Diana ngo-1981, futhi manje uKate Middleton (ogqoka inkosazana engasekho indandatho yokuthembisana), amasafire ayikhethelo elisemthethweni lobucwebe. ...Funda kabanzi -
Isafire: Itshe lokuzalwa likaSepthemba liza ngemibala eminingi
Itshe lokuzalwa likaSepthemba Itshe lokuzalwa likaSepthemba, isafire, liyisihlobo setshe lokuzalwa likaJulayi, irubi. Zombili ziyizinhlobo ze-mineral corundum, uhlobo lwe-crystalline lwe-aluminium oxide. Kodwa i-corundum ebomvu i-ruby. Futhi zonke ezinye izinhlobo zekhwalithi yegem ye-corundum zingamasafire. Yonke i-corundum, kuhlanganise ne-sapp...Funda kabanzi -
Amatshe ayigugu anemibala eminingi vs i-gemstone polychromy! Irubi yami yaphenduka yaba owolintshi lapho ibhekwa mpo?
Kubiza kakhulu ukuthenga itshe eliyigugu elilodwa! Ngingakwazi ukuthenga amatshe ayigugu anemibala emibili noma emithathu ngenani elilodwa? Impendulo iwukuthi uma itshe lakho eliyigugu eliyintandokazi liyi-polychromatic - lingakubonisa imibala ehlukene ngama-engeli ahlukene! Ngakho-ke yini i-polychromy? Ingabe amatshe ayigugu e-polychromatic asho...Funda kabanzi -
Ama-laser gemstone we-Femtosecond titanium anezimiso zokusebenza ezibalulekile
I-Femtosecond laser iyilaser esebenza ngamapulses anesikhathi esifushane kakhulu (10-15s) namandla aphezulu aphezulu. Ayigcini nje ngokusenza sikwazi ukuthola isixazululo sesikhathi esifushane kakhulu kodwa futhi, ngenxa yamandla ayo aphezulu, ithuthukiswe kakhulu emikhakheni eyahlukene yezimboni. I-titanium ye-femtosecond ...Funda kabanzi -
