Iyo abakiriya bakoreshagusya inkweto, bazita cyane cyane ku gukoresha ingaruka, zigaragaza ubuziranenge bwibicuruzwa ku rugero runini.Ubwiza bwo gusya inkweto bugenwa nimpamvu ebyiri, imwe nuburakari, igena ishingiro ryumurimo wigice,gusya inkwetohamwe nuburakari bwiza burashobora kunoza cyane imikorere yawe yakazi, ikabika umwanya wawe nigiciro cyakazi, ikindi kintu nigihe cyo kubaho, kigena ihiganwa ryibanze ryigice.

Niba inkweto zo gusya zidakabije bihagije, ntibizaba byoroshye kurangiza imirimo yo gusya, iki kibazo cyitwa igice ntigishobora kugabanywa, kandi igice nkicyo nticyemewe kumasoko.Hamwe niterambere ryinganda za diyama, kuri ubu, ibikoresho bya diyama ya Bontai hafi ya byose ntibibaho iki kibazo.

Igice cyo kwambara byihuse cyane byahindutse ibicuruzwa byingenzi inganda za diyama zikeneye gutsinda.Ubwa mbere, dukeneye kumenya ko impamvu zizatera iki kibazo.

1. Inkwano iroroshye cyane kuburyo ituma igice kitarwanya kwambara, igice kiri hamwe nigitereko cyuruhinja hamwe nifu ya pome ya diyama yo gucumura, mugihe inkwano idakomeye bihagije, kwambara bisanzwe birihuta, noneho gukoresha inkwano birihuta ifu ya diyama ifata imbaraga ntabwo ihagije, umubare munini wo kumena, bigatuma kugabanuka kwubuzima.Igice nk'iki, muburyo bwo gusya, diyama ntabwo yagize uruhare rwayo, bivamo imyanda.

2. Ifu ya diyama yibanze cyane.ifu ya diyama ni mike cyane, mugihe cyo gusya, ifu ya diyama izakoreshwa vuba cyane.

3. Gusya hejuru ni ugukabya gukabije cyangwa gukomera.ibi bizatera ifu ya diyama ikabije, nayo izagabanya igihe cyakazi

4. Gukora nabi.Abakoresha bamwe bakoresha umuvuduko ukabije, kugenda umuvuduko no guca ubujyakuzimu.igice mubikorwa birebire biremereye, imikorere yumubiri na chimique yagabanutse, bigatuma igice gihinduka cyane, bikavamo kurya cyane.

5. Igishushanyo cy'igice nticyumvikana.Niba imiterere yicyo gice yita cyane ku gukara, noneho igice gikunda guhura nibibazo byihuse.

Iyo uhuye niki kibazo cyagusya inkweto, nibyiza gukuraho ibibazo byubukanishi nabantu mbere, hanyuma ibitekerezo kuri twe, tuzahindura formulaire cyangwa dushushanye ibice bishya kugirango dukemure ibibazo.
