Umucyo w'urumuri rw'icyuma kidafunze nyuma yo gukurura ugena ubwiza bw'umuyoboro w'icyuma. Hari ibintu byinshi bigira ingaruka ku rumuri, ariko cyane cyane mu bintu bitanu bikurikira,

1. Niba ubushyuhe bukenewe bugera ku bushyuhe bukenewe, ubushyuhe bwo gufunga. Ubushyuhe bw'icyuma kidafunze muri rusange bufata umuti ushyushya, kandi abantu bakunze kwita "annealing", ubushyuhe buri hagati ya 1050 ~ 1100 DEG C. Ushobora kureba unyuze mu mwobo wo kureba w'itanura rifunga, ugomba kuba ufite agace k'icyuma kidafunze gafite imiterere ya incandescent, ariko nta mwanya wo koroshya.

2. Ikirere cyo gufunga. Muri rusange ikoreshwa rya hydrogen nziza nk'ikirere cyo gufunga, ikirere cy'ubuziranenge bwiza ni kirenga 99.99%, niba ikirere ari ikindi gice cya gazi idakora, ubuziranenge nabwo bushobora kuba buke gato, ariko ntibushobora kuba burimo ogisijeni nyinshi n'umwuka w'amazi.

3. Gufunga umubiri w'itanura. Ifuru irabagirana igomba gufungwa, igakurwa mu kirere cyo hanze; hakoreshejwe hydrogen nk'umwuka urinda, hagomba guhuzwa inzira imwe gusa (ikoreshwa mu gucana imyuka ya hydrogen). Uburyo bwo kugenzura bushobora gukoreshwa mu guhanagura amazi y'isabune mu itanura rikurura imyuka ya buri ngingo, kugira ngo harebwe niba gazi ikora; imwe mu myanya yoroshye gukoresha gazi ni umuyoboro w'itanura ukurura imyuka hanyuma umuyoboro ujya aho iherereye, impeta yo gufunga y'aho hantu yoroshye cyane kwambara, ugomba guhora ugenzura niba ihinduka kenshi.

4. Kurinda umuvuduko wa gaze. Kugira ngo hirindwe ko habaho gusohora amazi make, kurinda icyuma gishyushya gaze bigomba kugumana umuvuduko mwiza, niba birinda gaze ya hydrogen, muri rusange bisaba kurenza 20kBar.

5. Amazi y'ifuru. Ku ruhande rumwe, kugira ngo harebwe niba umubiri w'ifuru yumisha, habanje gushyirwaho itanura, umubiri w'ifuru ugomba kuba wumye; byombi ni ukureba niba amazi menshi asigaye mu itanura ry'umuyoboro w'icyuma kidashonga, umuyoboro wihariye hejuru niba hari imyobo, ntumenemo cyangwa ngo ushyiremo ikirere cy'ifuru cyangiritse burundu.
