Indlela yokwakha:

① Vula i-arhente yokuFumana (ngokukhululekileyo)

Kubandakanya iintlobo ezintathu: isanti emanziweyo yesanti, isanti eyomileyo ebumba, kunye nentlabathi ye-chemic aplid andsbud;

Imowudi evaliweyo evaliweyo

Ukuphoswa okukhethekileyo kusetyenziswa isanti yezimbiwa zendalo kunye negravel njengezinto eziphambili zokubumba (ezinjengokuphosa ukutyala, ukuphuthuma kwenkqubo, ukuphoswa kwendibano, ukuphosa okungalunganga, ukuphosa i-ceramic, njl.njl);

③ Ezinye iindlela zokuhlelwa

Ngokutsho kobushushu bokusebenza, ukutyhobozela kunokwahlulahlulwa ukuba kushushu (ubushushu obushushu ngaphezulu kune-billetstaly), ukunyanzelwa okufudumeleyo (ngaphantsi kwe-goardrystallic).
