Tumaze gukora ubudandaji bw’amahanga bw’amakara ya shisha imyaka myinshi, twasanze benshi mu bafise amaduka y’umubiri yo mu mahanga bahagaritse umutima ko amakara asanzwe adashobora gusha, kandi ibicuruzwa vyo gutwara kure-bizomeneka. Iyi carbone y’imirongo 35mm irahindurwa kandi igakorwa ifatanijwe n’ibintu bikoreshwa ku musi ku musi mu maduka yo mu mahanga.
Ku bijanye n’ibikoresho vya mbere, dushimika ku mpumuro y’umuyagankuba isukuye kugira ngo tugabanye igitigiri c’ibintu bihumanye. Uburyo bwo gusohora bukoresheje umuvuduko munini -bukoreshwa mu gihe co guhingura, kandi imirongo irashirwa hanze ku ruhande rwa carbone igihe kimwe. Mu ntango, abakiriya benshi biyumvira yuko iyo nzira yari nziza gusa kugira ngo umuntu ashobore gucana umuriro, mugabo iyo umuntu ariko arayikoresha vy’ukuri, yari yumvikana neza. Umuyaga wari ugenda neza, kandi amakara yose yarashushe kimwe, kandi igice cayo nticari guturika ningoga.
Amakara menshi aremereye cane yo muri iyo nganda nyene, yoroshe gusenyuka no gusenyuka iyo akozweko n’ibintu bitwara. Twarahinduye igipimo c’ugufatanya kw’ibikoresho vya mbere, kandi igicuruzwa giheza kiragira ubukomezi bwiza kuruta. Mu gihe umuntu akoresha mu buryo busanzwe, ibuye rimwe rishobora guturika ataco rihinduye mu kiringo c’isaha imwe, kandi iduka ry’ibiyayuramutwe rifise abantu benshi ntirikeneye gusubirira umuriro w’amakara kenshi, ivyo bikaba bishobora kuzigama inguvu nyinshi z’abantu n’amahera menshi akoreshwa. Umunuko uva mu guturika ni umuco, ntuzopfuka uburyohe bw’itabi ubwaryo, ni co gituma kandi abakiriya benshi ba kera babandanya gusubiza amategeko.
Ivyo bikoresho bikoresha uburyo bwo gupfunyika ibintu bimwe, ku ruhande rumwe, ivyo bipande vy’umuyagankuba biratandukanywa mu gihe co gutwara, kugira ngo bigabanye ivyonona iyo bitomboye; Ku rundi ruhande, ubukonje bw’ibikoresho vy’ubwato bwo mu kiyaga burahinduka cane, kandi igikoresho gishizweko amazi-gishobora gukingira ubukonje-ku rugero runaka, kugira ngo ntihagire ingorane yo gucana umuyagankuba umaze gushika.
Turashobora gukora ibikorwa vyo guhindura ibintu vy’abaguzi, gushigikira gucapura LOGO ku bipapuro vyo hanze no guhindura uburyo bwo gukora. Uruganda rufise urutonde rw'ibikorwa rudahinduka umwaka wose, kandi rushobora kwemera amategeko y'igihe kirekire-y'ibikoresho vyose-. Ikaze abacuruzi b’ingero bava kw’isi yose kugira ngo bavugane kandi bavugane ku bijanye n’ibigereranyo.
