Ukuba unqwenela ibhegi, kwaye incwadi yemiyalelo ithi sebenzisa ulusu, yintoni impendulo yakho yokuqala? Iphezulu, ithambile, iklasikhi, ibiza kakhulu… Nokuba kunjalo, xa ithelekiswa neyesiqhelo, inokunika abantu uluvo oluphezulu ngakumbi. Enyanisweni, ukusebenzisa ulusu lokwenyani oluyi-100% kufuna ubunjineli obuninzi ukuze kucutshungulwe izixhobo ezisisiseko ezinokusetyenziswa kwiimveliso, ngoko ke ixabiso lezinto ezisisiseko liya kuba phezulu.
Ukwahluka, ngamanye amazwi, ulusu lunokwahlulwa lube ngamanqanaba aphezulu kunye namanqanaba aphantsi. Eyona nto ibalulekileyo yokuqala ekumiseleni olu luhlu 'lulusu oluluhlaza'. 'Ulusu lokuqala' lulusu lwesilwanyana olungalungiswanga, oluyinyani. Oku kubalulekile, kwaye oko kubalulekile, kodwa akukho nanye kuzo enokuthelekiswa nomgangatho wezinto eziluhlaza. Kuba le nto iya kuchaphazela umgangatho wemveliso yonke.
Ukuba sifuna ukuguqula ulusu olungavuthwanga lube zizinto zemveliso, kufuneka sidlule kwinkqubo ebizwa ngokuba yi-'tanning leather'. Oku kubizwa ngokuba yi-'Tanning' ngesiNgesi; yi-'제혁 (tanning)' ngesiKorea. Imvelaphi yeli gama kufuneka ibe yi-'tannin (tannin)', nto leyo ethetha izinto eziluhlaza ezisekelwe kwizityalo.
Ulusu lwesilwanyana olungalungiswanga lunokubola, izinambuzane, ukungunda kunye nezinye iingxaki, ngoko ke lucutshungulwa ngokwenjongo yokusetyenziswa. Ezi nkqubo zibizwa ngokuba yi "tanning". Nangona kukho iindlela ezininzi zokucutshungulwa, "isikhumba esifakwe i-tannin" kunye "nesikhumba esifakwe i-chrome" zisetyenziswa rhoqo. Ukuveliswa kolusu ngobuninzi kuxhomekeke kule ndlela 'ye-chrome'. Enyanisweni, ngaphezulu kwe-80% yemveliso yolusu yenziwe 'ngesikhumba se-chrome'. Umgangatho wolusu olufakwe imifuno ungcono kunolusu oluqhelekileyo, kodwa kwinkqubo yokusetyenziswa, uvavanyo lwahlukile ngenxa yokwahluka kwizinto ozikhethayo, ngoko ke ifomula ethi "isikhumba esifakwe imifuno = isikhumba esihle" ayifanelekanga. Xa kuthelekiswa nolusu olufakwe i-chrome, ulusu olufakwe imifuno lwahlukile kwindlela yokucubungula umphezulu.
Ngokubanzi, ukugqitywa kwesikhumba esifakwe i-chrome kukwenza ulungiso oluthile kumphezulu; isikhumba esifakwe imifuno asidingi le nkqubo, kodwa sigcina imibimbi kunye nobume besikhumba. Xa sithelekiswa nesikhumba esiqhelekileyo, sihlala ixesha elide kwaye siyaphefumla, kwaye sineempawu zokuba sithambile xa sisetyenziswa. Nangona kunjalo, ngokwemigaqo yokusetyenziswa, kunokubakho iingxaki ezingaphezulu ngaphandle kokulungiswa. Ngenxa yokuba akukho filimu yokugquma, kulula ukukrweleka nokudaywa, ngoko ke kunokuba nzima ukuyiphatha.
Ingxowa okanye isipaji sokuchitha ixesha elithile nomsebenzisi. Ekubeni kungekho nto igqunyiweyo phezu kolusu olufakwe imifuno, lunomzimba othambileyo kakhulu njengolusu losana ekuqaleni. Nangona kunjalo, umbala kunye nemilo yalo iya kutshintsha kancinci ngenxa yezizathu ezifana nexesha lokusetyenziswa kunye neendlela zokugcina.
