Umucanga w’amabara karemano ukomoka ku Isi. Ukomoka ku mabuye n’imyunyu ngugu irimo amarangi. Okiside y’icyuma ni kimwe mu bintu bisanzwe bikoreshwa mu guhanga amabara karemano, bigira uruhare mu gutuma habaho amabara atukura, orange n’umukara agaragara mu mucanga w’amabara karemano menshi. Urugero, amabara y’umutuku n’umukara y’umucanga umwe wo mu butayu akomoka ku kuba ufite oxide y’icyuma. Manganese ishobora gushyiramo amabara y’umukara cyangwa umuhengeri, mu gihe imvange y’umuringa ishobora kugira uruhare mu mabara y’icyatsi n’ubururu. Gukuramo umucanga w’amabara karemano bitangirana n’ibikorwa byo gucukura amabuye cyangwa inzuzi aho ayo maranga aherereye. Iyo umaze gucukurwa, ibikoresho fatizo binyura mu ntambwe nyinshi zo gutunganya. Gusya amabuye manini mo uduce duto, hagakurikiraho kuyacukura kugira ngo umucanga utandukanye ingano y’ibinyampeke. Hanyuma hakorwa igikorwa cyo gukaraba kugira ngo hakureho imyanda nk’ibumba, umukungugu, n’ibindi bintu bidakenewe, kugira ngo umucanga ube ufite ubuziranenge bwo hejuru n’ubukana bw’amabara wifuza.

Umucanga w'amabara y'ubukorano, mu buryo butandukanye, ukorwa binyuze mu buryo bwakozwe n'abantu. Ubusanzwe, ibikoresho by'ibanze, akenshi umucanga wa quartz bitewe n'ubwinshi bwawo, ubukana bwawo, n'amabara atagira aho ahuriye, ni byo shingiro. Uburyo bugezweho bwo gusiga irangi bukoreshwa mu gusiga irangi ku duce tw'umucanga wa quartz. Abakora bakoresha irangi ry'ubuziranenge n'ibintu bifatika byo guhuza kugira ngo barebe ko ibara rifata neza ku duce tw'umucanga. Uburyo bwihariye bwo gusiga bushobora gukora urwego rw'amabara rumwe kandi ruramba, bigatuma habaho ubwoko bwinshi bw'amabara ashobora kugorana kuboneka mu buryo busanzwe. Binyuze mu kugenzura neza inzira yo gukora, umucanga w'amabara y'ubukorano ushobora kugera ku bwiza bw'amabara buhamye no gukwirakwiza ingano y'uduce, byujuje ibisabwa bikomeye by'inganda zitandukanye.
