Itandukaniro riri hagati yindorerwamo ya feza nindorerwamo isanzwe:
1. Indorerwamo ya feza isizwe na nitrate ya silver, ntibyoroshye okiside na rust. Indorerwamo zisanzwe zirashobora gusimbuza nitrate ya silver na nitrate ya mercure cyangwa sulfate ya mercure kugirango uzigame ibiciro. Nyamara, mercure ntabwo ihagaze neza nka feza kandi biroroshye okiside na ingese.
2. Indorerwamo ya feza irasobanutse neza kuruta indorerwamo isanzwe, kandi impande ya geometrike yerekana ibintu bitanga urumuri ni byinshi. Kugaragaza indorerwamo zisanzwe ni bike. Kugaragaza indorerwamo zisanzwe ni 70%. Imiterere n'amabara bigoreka byoroshye, kandi ubuzima bwa serivisi ni bugufi, kandi kurwanya ruswa ni bibi.
3. Kubireba ubuziranenge, muri rusange ni mercure, ariko ubwiza nuburyo bwo gukora buratandukanye cyane. Ibicuruzwa byujuje ubuziranenge bigomba kuba bitarimo amazi, kandi ntibizagoreka igihe. Ibicuruzwa bisanzwe bizaba bihenze mugihe runaka.
1. Indorerwamo y'ubwiherero.
2. gukora indorerwamo ikurikirana hamwe nubwoko bwinshi kandi ikunzwe cyane nabagore bigezweho.
D. ibikoresho nkumufasha. Bitewe nuburyo bugari bwo gukoresha, bigize igice cyingenzi cyurukurikirane rwindorerwamo.
4. Nibikorwa byindorerwamo byubuhanzi cyane, bishushanya.
5.
6. Nukwagura imiterere yo gushushanya indorerwamo mubindi nganda mumyaka icumi ishize.
