Kupfava
Muzvikomo zveEcuador munomera uswa hunonzi toquilla, hunde hwahwo hunogona kurukwa kuva ngowani pashure pokunge warapwa. Heti iyi yaifarirwa nevashandi vepaPanama Canal nekuti yaive yakareruka, yakapfava uye yaifema, uye yaizivikanwa se "Panama hat". Iwe unogona kupeta chinhu chose kumusoro, uiise kuburikidza nemhete uye uipete pasina kuunyana. Saka inowanzoputirwa mucylinder uye yakapetwa kana isina kupfeka, zvichiita kuti zvive nyore kutakura.
Imwe yezvivezwa zvaBernini zvinonyanya kupembererwa ndeyemashiripiti "Pluto Snatching Persephone", apo Bernini akagadzira ingangove "yakapfava" marble munhoroondo yevanhu, ichiratidza kunaka kwepamusoro kwemarble mu "kupfava" kwayo.
Kupfava ndiwo maonero akakosha anopa vanhu pfungwa yekuzivikanwa. Vanhu vanofarira kupfava, pamwe nekuti hakutiunzi kukuvadza kana njodzi, asi chengetedzo nekunyaradza chete. Kana masofa ese mudzimba dzeAmerica aive maChinese akasimba ehuni funniture, hapafanirwe kuve nembatatisi dzakawanda kudaro, handiti?
Nokudaro, nokuda kweganda, kupfava kwagara kuri chimwe chezvinhu zvinozivikanwa zvikuru nevatengi. Zvingave zvipfeko, fenicha, kana chigaro chemotokari.
Chigadzirwa chinonyatsoshanda chekunyorova mukugadzirwa kwematehwe ndiko mafuta.
Kupfava kweganda ndiko mhedzisiro pane chinangwa chemafuta, inova kudzivirira iyo fiber chimiro kubva pakunamatira zvakare panguva yekuomeswa (dehydration) process.
Asi mune chero mamiriro ezvinhu, kushandiswa kwemafuta, kunyanya mamwe echisikigo, anogona kuguma nematehwe akapfava uye akasununguka. Zvisinei, kunewo matambudziko: mafuta akawanda echisikigo ane kunhuhwirira kusingafadzi kana kutsvuka nekuda kwenhamba huru yezvisungo zvisina kuvharwa muchimiro chavo. Synthetic fatliquors, kune rumwe rutivi, haitamburi nedambudziko iri, asi kazhinji haina kupfava uye yakasununguka sezvinodiwa.
Sarudzo ine chigadzirwa chimwe chinogadzirisa dambudziko iri uye inowana zvinoshamisa kuita:
