Ibicuruzwa bimaze gusiga, dushyira ibicuruzwa mumatara kugirango tubanze turase.Guhuha umukungugu wa ceramic mbere yo kurasa birashobora kuzamura neza umusaruro wibicuruzwa.Umukungugu uri hejuru yibicuruzwa bivanwaho, kandi ntabwo byoroshye gutera ibicuruzwa kubyara ibice.

Kurasa ninzira ikomeye cyane mubikorwa byubutaka.Nyuma yo gushyirwaho no gusiga irangi, ibicuruzwa byarangije gukorwa birashobora gukurikiranwa gusa nubushyuhe bwumubiri nubumara bitewe nubushyuhe bwo hejuru, hanyuma amaherezo bigaragara ko ari hafi ya zeru, kugirango ugere ku ntera yuzuye ya farashi.Iyi nzira yitwa "kurasa".

Kubera ibyiza byakarere, uruganda rwacu rufite urubuga runini nibikoresho byo kurasa ibicuruzwa.Dukoresha itanura rya tunnel kugirango tubyare umusaruro.Igihe cyo kurasa ni kirekire.Amashanyarazi, gloss, hamwe nubushyuhe bwumuriro nibyiza kuruta ibyakoreshejwe munganda zisanzwe Roller itanura ni nziza cyane.

Mugihe kimwe, itanura rya tunnel rirakomeza, uruziga ni rugufi, ibisohoka ni binini, kandi ubuziranenge buri hejuru.Ikora ihame ryo guhuza, bityo igipimo cyo gukoresha ubushyuhe ni kinini, kandi lisansi nubukungu.Kuberako kubika ubushyuhe no gukoresha ubushyuhe ari byiza, lisansi nubukungu.Ugereranije n’itanura rya flame itavanze, irashobora kuzigama hafi 50-60% ya lisansi.kuzamura ireme.Ubushyuhe bwibice bitatu byahantu hashyuha, agace ka firigo na zone ikonjesha bikunze kubikwa murwego runaka, bigatuma byoroha kumva itegeko ryo kurasa, bityo ubwiza nabwo bukaba bwiza kandi igipimo cyangiritse kikaba gito.
