Isikali ... Zingaphi iingxaki eziza kuzisa kwiikhitshi eziqeqeshiweyo, amashishini okuvelisa izinto kwaye kunjalo, kubomi bemihla ngemihla.
Kuya kubonakala ngathi kamsinya nje ukuba i-proveluting yobugcisa yayiyenzeka kwaye abantu baqala ukusebenzisa amathuba amaninzi kunye namathuba aphezulu enkqubela-nkqo, ubonelelo lwamanzi, ukubilisa amanzi, ukubilisa okuzenzekelayo kunye nokubila apha. Kutheni le nto ivela?
Impendulo ilula kakhulu apha. Inyani yile yokuba inkqubo yokucwangciswa inxulumene ngokusondeleyo nomxholo weetyiwa, i-quartz, i-rust kunye nezinye izinto ezingcolileyo, okanye kunokuba zizinto zayo.
Umbuzo ophambili yindlela yokujongana nayo? Zininzi iindlela zokulwa nesayensi. Kubomi bemihla ngemihla, idla ngokubonakala kwiindlela ze-felk, ezinje nge-lemon acid okanye isoda. Kodwa kumashishini akunakwenzeka ukuba wenze ngaphandle kwe-chemistry yobungcali. Ngendlela, kufuneka itshilo ukuba ukusetyenziswa kweearhente zokufuya ukususa umlinganiso kubomi bemihla ngemihla akunjalo. Kunzima ukufezekisa iziphumo zomgangatho ngaphandle kokusetyenziswa okhethekileyo.
Ngethamsanqa, amaxesha entsilelo ixesha elide emva kokuba, namhlanje, kwiintlobo ezahlukeneyo zengxowa-mali eboniswe kwimarike, unokukhetha ngqo into efanelekileyo kuwe. Iimveliso zobungcali ukususa isikali, njenge-belgian ye-bienolux, inokuthengwa kwakhona njengoko sele iqhelekile kwaye ithandile ngabathengi
Iimali zobungcali zenziwa kuthathelwa ingqalelo zonke iimpawu ezinokuthi ziphumeze ukusebenza kweendlela zobugcisa zibandakanyiwe kwindawo yomngcipheko. Ke ngoko, zezona zinto zibalulekileyo kwaye zisengqiqweni. Sukugcina izixhobo ezikhusela ubuchule bakho, kuba ithembisa kakhulu kwaye indleko ngakumbi. Ngayiphi na imeko, isitshixo sempumelelo kumlo ochasene namanqanaba - amanyathelo okhuseleko kunye nokucwangciswa rhoqo!
