Okokuqala, ukuhambisa:
I-1. Kuba umsebenzi osebenzayo onesimo esibuhlungu okanye utshintsho olubukhali lwecandelo kunye nobunzima obukhulu, kufuneka buphandwe
2. Indlela yokuqhubela phambili yile: Ukukhetha i-800 ℃, indawo yesibini ehambayo yi-500 ~ 550 ℃ kunye ne-850 ℃, iqondo lokunyuka kweqondo lokushisa eliphambili kufuneka lilinganiselwe
Zimbini, ukufudumeza:
I-1. Kukho ii-nofs kunye nemingxunya yokusebenza, ukulahla kunye neenxalenye ze-weldied kunye nokusebenza kwentsimbi engenasitayile, ngokubanzi kungekuko ukufudumeza
2. Qinisekisa ukuba umsebenzi wokusebenza ushushu kangangexesha elaneleyo. Bala ubukhulu obusebenzayo bomsebenzi kunye nobunzima obunemiqathango (owona mgangatho wokwenene
Ezintathu, ukucoca:
I-1. Umsebenzi wokuSebenza kunye noMkhenkce kufuneka ucocwe kwioyile, ityuwa yentsalela, ipeyinti kunye nezinye izinto zangaphandle ngaphambi konyango lobushushu
2. Umxholo osetyenziswe okokuqala kwiziko le-vacuum kufuneka udinwe kwaye uhlanjululwe kwangaphambili phantsi kwenqanaba lokusebenza elifunwa ngumsebenzi
Ukulayisha ezine,
I-1. Kwinkqubo yonyango lobushushu, umsebenzi obonakalayo obonakalayo kufuneka uvutha ngummiselo okhethekileyo
2. Umsebenzi osebenzayo kufuneka ubekwe kwindawo yokufudumeza
