Embindini wenkulungwane yeshumi elinesithoba, uninzi lwamafama aqala ukubanga umhlaba oyinkangala kwaye afudukela ngasentshona ukuya kumathafa kunye nomda osemazantsi-ntshona ngokulandelelanayo. Ngenxa yokufuduka kwezolimo, amafama akuqonda ngakumbi ukutshintsha okusingqongileyo. Phambi kokuba umhlaba ubuyiselwe, wawuzele ngamatye yaye kungekho manzi. Emva kokufuduka kwezolimo, ngenxa yokunqongophala kwezixhobo zezolimo zengingqi kunye nobuchwepheshe bezolimo obuhambelanayo, iindawo ezininzi zazingahlali mntu, kwaye zazingabanikazi. Kwimeko-bume entsha yokutyala, ukuze ikwazi ukumelana nale meko, abalimi abaninzi baqalisa ukubiyela ngocingo oluhlabayo kwiindawo zabo zokutyala.
Ngenxa yokunqongophala kwezinto ekubuyiselweni komhlaba ekuqaleni, kwingcamango yemveli yabantu, udonga olwenziwe ngamatye kunye nemithi inokudlala indima yokukhusela, enokukhusela imida yayo ekutshatyalalisweni ngamanye amandla angaphandle kwaye inyathelwe zizilwanyana, ngoko ke ulwazi lokukhusela lunamandla.
Ngenxa yokunqongophala kweenkuni namatye, abantu bahlala bekhangela ezinye iindlela zocingo oluqhelekileyo ukukhusela izityalo zabo. Kwiminyaka ye-1860 kunye ne-1870, abantu baqala ukulima izityalo ngameva njengezicingo, kodwa ngesiphumo esincinci.
Ngenxa yokunqongophala kunye namaxabiso aphezulu ezityalo, kunye nobunzima bokwakhiwa, bashiywa ngabantu. Ngenxa yokunqongophala kocingo, inkqubo yokubuyiselwa komhlaba ayizange ihambe kakuhle.
Ngo-1870, isilika egudileyo ekumgangatho ophezulu yayifumaneka ngobude obahlukeneyo. Abafuyi basebenzise ezi ngcingo zigudileyo ukurhangqa ucingo, kodwa bafumanisa ukuba iinkukhu zazingena ziphuma.
Kwandula ke, ngowe-1867, abavelisi ababini bazama ukongeza imiqolo kwisilika egudileyo, kodwa akuzange kubekho nto isebenzayo. Ukuza kuthi ga ngo-1874, uMichael Kelly wavelisa indlela esebenzayo yokongeza ameva kwisilika, waza waqalisa ukuyisebenzisa ngobuninzi.
UJoseph Glidden wafumanisa ukuba kukho intambo yomthi kwilali encinci eqhelekileyo. Kukho izikhonkwane zentsimbi ezininzi ezibukhali kwelinye icala lentambo, kwaye iingcingo ezigudileyo zibotshelelwa kwelinye icala. Oku kufunyenweyo kwamvuyisa kakhulu. Kwakhona yenza ukuba ukuveliswa kwakhe kubonakale kwimilo yocingo oluhlabayo. I-Glidden yabeka i-spines kwisisiyi seembotyi zekofu, emva koko yajija ama-spines ngamaxesha athile ngocingo olugudileyo kwaye yajija olunye ucingo olujikeleze iminqonqo ukuyibamba.
I-Glidden yaziwa ngokuba nguyise wocingo oluhlabayo. Emva kokuyilwa kwakhe ngempumelelo, isaqhubeka ukuza kuthi ga kulo mhla ngokuqanjwa kwamalungelo omenzi angaphezu kwama-570 ocingo oluhlabayo. "Yenye yezinto eziqanjiweyo ezitshintshe ubuso behlabathi".
E-China, uninzi lweefektri ezivelisa ucingo oluhlabayo lusebenza ngokuthe ngqo ucingo olwenziwe ngamazimba okanye ucingo lwentsimbi oluqatywe ngeplastiki lube lucingo oluhlabayo. Le ndlela yokuluka kunye nokujija ucingo oluhlabayo iya kuphucula ukusebenza kakuhle kwemveliso, kodwa ngamanye amaxesha kukho ukungonakali ukuba ucingo oluhlabayo alulungiswanga ngokwaneleyo.
Ngophuhliso lwetheknoloji, abanye abavelisi ngoku baqala ukusebenzisa inkqubo ethile yokufaka i-embossing, ukwenzela ukuba umphezulu wentonga yocingo awusekho ngokupheleleyo, ngaloo ndlela uphucula kakhulu umphumo wokuzinzisa i-pitch.
Ngameva ayo abukhali, ubomi benkonzo ende, kunye nofakelo olufanelekileyo kunye nolungenamkhawulo, ucingo oluhlabayo lusetyenziswe ngokubanzi kwiigadi, iifektri, iintolongo kunye nezinye iindawo ezifuna ukuba zodwa, kwaye ziqatshelwe ngabantu.
Kuthekani ngayo? Ndiyazibuza ukuba umangaliswe njengam ukuba ucingo oluhlabayo lunembali enomdla kangaka?
Ukuba unolwazi oluncinci malunga nocingo oluhlabayo, wamkelekile ukuba unxibelelane nathi.
