Nakuba sonke sazi isikhunta somshini wezitini ongashi, abantu abaningi abazi ukuthi lwenziwa kanjani lolu hlobo lwesikhunta. Ake ngikwethule. Okokuqala, kunezinhlobo eziningi zokubunjwa komshini wezitini, njengesikhunta sezitini esingenalutho, isikhunta esijwayelekile sezitini, isikhunta sesitini sombala kanye nesikhunta esithandana nabobulili obuhlukile. Ngokombono wezinto ezibonakalayo, kunezinhlobo ezintathu ngokuyisisekelo. Esokuqala isikhunta esenziwe ngensimbi evamile, esihlukaniswa sibe isikhunta esiphezulu nesingezansi, Esesibili senziwa ngensimbi ye-manganese engunombolo-15, njengesaha lokusika imabula. Eyesithathu isikhunta se-zinc carbon, esilingana nensimbi ye-manganese enguNombolo 65. Uma iphezulu ilebula ye-manganese, kuba nzima kakhulu amandla ayisihlobo amelana nokugqokwa, kodwa futhi kulula ukuba brittle. Yingakho isikhunta ngokuvamile sisesimweni esihle kakhulu lapho i-manganese ingama-65 kuphela. Kungakhathaliseki ukuthi ilebula iphakeme kangakanani, inamandla, kodwa kulula ukuphuka. Uma ilebula iphansi, ayinawo amandla futhi ayinawo ukumelana nokuguga. Lesi isingeniso esifushane sesikhunta.
