Ukushisa ngokukhanya (bright annealing) inqubo yokushisa eyenziwa endaweni engenamoya noma endaweni elawulwayo equkethe amagesi angasebenzi (anjenge-hydrogen). Leli gesi elilawulwayo linciphisa ukugqwala kwengaphezulu kube kuncane kakhulu okuholela ekutheni ingaphezulu likhanye kakhulu futhi ungqimba lwe-oxide lube luncane kakhulu. Ukuhlanzwa nge-asidi (pickling) akudingekile ngemva kokushisa ngokukhanya ngoba ukugqwala kuncane. Ngenxa yokuthi akukho ukuhlanzwa nge-asidi, ingaphezulu libushelelezi kakhulu okuholela ekumelaneni kangcono nokugqwala okubanga imigodi (pitting corrosion).

Ukwelashwa okukhanyayo kugcina ukubushelelezi kwendawo egoingqoziwe, futhi indawo ekhanyayo ingatholakala ngaphandle kokucubungula okwengeziwe. Ngemva kokukhanyiswa okukhanyayo, indawo yeshubhu lensimbi igcina ubucwebe bensimbi bokuqala, futhi kutholakala indawo ekhanyayo eseduze nokubukeka kwesibuko. Ngaphansi kwezidingo ezijwayelekile, indawo ingasetshenziswa ngqo ngaphandle kokucubungula.

Ukuze ukuthambisa okukhanyayo kusebenze kahle, senza izindawo zeshubhu zihlanzeke futhi zingabi nakho konke okungaphandle ngaphambi kokuthambisa. Futhi sigcina umoya wokuthambisa e-oven ungenawo umoya-mpilo (uma kufuneka umphumela okhanyayo). Lokhu kwenziwa ngokususa cishe yonke igesi (ukudala i-vacuum) noma ngokushintsha umoya-mpilo ne-nitrogen nge-hydrogen eyomile noma i-argon.

Ukuthambisa okukhanyayo nge-vacuum kukhiqiza ishubhu elihlanzeke kakhulu. Leli shubhu lihlangabezana nezidingo zemigqa yokuhambisa igesi ehlanzeke kakhulu njengokuba bushelelezi ngaphakathi, ukuhlanzeka, ukuthuthukiswa kokumelana nokugqwala kanye nokunciphisa ukukhishwa kwegesi nezinhlayiya ezivela ensimbi.

Imikhiqizo isetshenziswa emathuluzini anembile, imishini yezokwelapha, amapayipi ahlanzekile kakhulu embonini ye-semiconductor, amapayipi ezimoto, amapayipi egesi aselabhorethri, i-aerospace kanye nochungechunge lwemboni ye-hydrogen (umfutho ophansi, ophakathi, ophezulu) kanye namapayipi ensimbi angagqwali e-UHP (Ultra High Pressure) kwezinye izindawo.

Siphinde sibe nesitoko samashubhu angaphezu kuka-100,000 wamamitha, okungahlangabezana namakhasimende anesikhathi esiphuthumayo sokulethwa.
