Ngo-1877, uFremi, usokhemisi ongumFulentshi, wasebenzisa impushana ye-alumina emsulwa, i-potassium carbonate, i-barium fluoride kanye nenani elincane le-potassium bichromate njengezinto zokusetshenziswa. Ngemuva kwezinsuku ezingu-8 zokushisa okuphezulu okuncibilika ku-crucible, amakristalu amancane e-ruby atholakala, okwakuyisiqalo se-ruby yokwenziwa.
Ngo-1900, ososayensi basebenzisa i-aluminium oxide ngemva kokuncibilikisa inani elincane le-chromium oxide, i-Cr2O3, ngokwesilinganiso sesisindo sika-0. Nge-7% indlela eyengeziwe, amarubi angu-2g ~ 4g akhiqizwa. Namuhla, amarubi namasafire amakhulu amagremu angu-10 angenziwa.
Ngo-1885, kwavela amarubi okwenziwa ekhwalithi ephezulu eGeneva, eSwitzerland. Kuthiwa kunezicucu zerubi zemvelo, kanye ne-potassium dichromate ebomvu nokunye ukuncibilika kwezinga lokushisa eliphezulu okwenziwe, kanye nemvelo yemikhiqizo yemvelo. Kodwa-ke, kwakungusokhemisi ongumFulentshi u-Verneuil owakha itshe eliyigugu futhi walifaka ekukhiqizeni okukhulu.
Ngo-1891, u-Verneuer wasungula inqubo yokuncibilikisa amalangabi futhi wayisebenzisa ukwenza amagugu okwenziwa. Ngemva kwempumelelo, wazama nge-alumina ehlanzekile. Ukuhlolwa kwenziwa esithandweni se-Muffle esinezinga lokushisa eliphezulu elinepayipi eliphehla umoya we-hydrogen ne-oxygen. Impushana ecolekile ye-alumina emsulwa equkethe inani elincane le-chromium oxide yehliselwa kancane kancane elangabini futhi yancibilika, yaconsa esisekelweni ukuze iminyanise futhi icwebezele. Ngemva kweminyaka eyishumi yokusebenza kanzima.
Amarubi okwenziwa enziwa nguVernayet ngo-1904, futhi kusukela ngaleso sikhathi ukuncibilika kwelangabi kuye kwaphelela ukukhiqiza amarubi cishe angenakuhlukaniswa kwemvelo. Le ndlela isetshenziswe kuze kube yizikhathi zanamuhla futhi kuseyindlela eyinhloko yokukhiqiza amagugu okwenziwa emhlabeni, eyaziwa ngokuthi "indlela ye-Verneuil". Manje kuthatha amahora ambalwa kuphela ukukhiqiza ngaphezu kwe-100 carats yetshe eliluhlaza le-ruby, amakristalu e-corundum yokwenziwa ngokubukeka kwepear shape noma isimo sesanqante, ukuthungwa okumsulwa, ukukhanya kombala ngisho nangaphezu kwemikhiqizo yemvelo, kanye nezinzuzo ezinkulu zezomnotho. Inqubo yesimanje ye-Verneuil ayikhiqizi kuphela amarubi asukela ku-pink ekhanyayo kuya kubomvu obujulile, kodwa namasafire emibala ehlukahlukene, ngisho namarubi namasafire anokukhanya kwenkanyezi. Kuyisimangaliso.
