Igikorwa cyo gukora ibyuma biciriritse byibyuma birashobora gufatwa nkikimenyetso cyinganda gifite ibyiyumvo "byiza". Guhindura kuva mubyuma bishongeshejwe bikozwe mubyuma bisa neza bihuza igikundiro cyo kugenzura neza hamwe nikoranabuhanga rikomeye kuri buri ntambwe.
Ubwa mbere, uburyo bwo gukora ibyuma bwuzuyemo ingaruka zigaragara – ibyuma bishongeshejwe kuri 1600 ℃ byuma bihindura, kandi umwuka wa ogisijeni utera imbunda nkinkota ityaye, uhita urekura ibishashi hamwe n’imiti ikaze, bikuraho nta mpuhwe. Muri kano kanya, ibyuma bishongeshejwe ni nka magma yamenyereye, igenda ikomera buhoro buhoro mumashini ikomeza, ihinduka icyapa kinini kandi kinini. Ubuso butukura busa nkaho bugikomeza kuvuga ubukana nonaha.
Kwinjira murwego rwo kuzunguruka, ibyiyumvo "byiza" bijyana kurwego rukurikira. Icyapa cy’ubushyuhe bwo hejuru kigaburirwa mu ruganda rugari kandi runini cyane, aho imizingo minini isa n’imikindo y’ibihangange by’ibyuma, buri kanda ikajyana no kuniha no guhindura ibyuma. Sisitemu ya mudasobwa igenzura imbaraga zizunguruka, ubushyuhe, n’umuvuduko mugihe nyacyo, buhoro buhoro kunanuka no kwagura icyuma mubyuma bya milimetero neza. Ikintu gitangaje cyane ni tekinoroji "igenzurwa no gukonjeshwa no gukonjesha": icyapa gishya gitukura cyahise cyinjira muri sisitemu yo gukonjesha amazi, kandi nozzles amagana atera igihu cyumuvuduko ukabije wamazi kugirango akore umwenda wera. Ubuso bwa plaque yicyuma burahinduka kuva umutuku ugahinduka imvi zijimye mumasegonda make, kandi imiterere yimbere yarubatswe neza. Gukomera no gukomera biringanijwe neza muriki gihe.
Hanyuma, isahani yicyuma, yagororotse, igenzurwa, kandi igacibwa, irambaraye nk’indorerwamo mu bicuruzwa byarangiye, hamwe n’itandukaniro rikomeye riri hagati y’ibyuma bikonje bikonje n’ubushyuhe butangwa mu gihe cyo gukora. Uku kugenzura neza kuva mubushyuhe bukabije kugeza gutuza rwose ni ibisobanuro byiza cyane mugikorwa cyo gukora ibyuma biciriritse biciriritse – ukoresheje ingufu zinganda kugirango uhindure ibyuma byo mwishyamba muri skeleton yibanze ifasha inyubako zigezweho, ibiraro, nibikoresho.
