Izipili zesilivere zeglasi ziveliswa ngokutyabeka umaleko wesilivere kunye nomaleko wobhedu kumphezulu weglasi edadayo ekumgangatho ophezulu ngokubekwa kweekhemikhali kunye neendlela zokutshintsha, emva koko zigalela iprimer kunye netopcoat kumphezulu womaleko wesilivere kunye nomaleko wobhedu njengomaleko wesilivere. umaleko okhuselayo. Yenziwe. Ngenxa yokuba yenziwe ngokusabela kweekhemikhali, kulula ukusabela ngokwekhemikhali ngomoya okanye ukufuma kunye nezinye izinto ezingqongileyo ngexesha lokusetyenziswa, okubangela ukuba umaleko wepeyinti okanye umaleko wesilivere uxobuke okanye uwe. Ngoko ke, iteknoloji yokuvelisa kunye nokucubungula, indawo, Iimfuno zobushushu kunye nomgangatho zingqongqo.
Izipili ezingenazo ikopolo zikwabizwa ngokuba zizipili ezihambelana nokusingqongileyo. Njengoko igama lithetha, izibuko azikho ngokupheleleyo ubhedu, oluhluke kwizibuko eziqhelekileyo ezinobhedu.
