Emva kokuba imveliso ikhazimle, sibeka imveliso kwiziko lokudubula kwangaphambili.Ukuvuthela uthuli lweceramic ngaphambi kokudubula kunokuphucula ngokufanelekileyo isivuno semveliso.Uthuli oluphezu kwemveliso luyasuswa, kwaye akulula ukwenza ukuba umkhiqizo uvelise amaqhekeza.

Ukudubula yinkqubo ebaluleke kakhulu kwimveliso ye-ceramic.Emva kokubunjwa kunye nokukhanya, imveliso egqityiweyo inokuthi iqhube uchungechunge lweempendulo zomzimba kunye neekhemikhali phantsi kwesenzo sokushisa okuphezulu, kwaye ekugqibeleni i-porosity ebonakalayo isondele kwi-zero, ukuze kufezekiswe iqondo elixineneyo le-porcelain.Le nkqubo ibizwa ngokuba "ukudubula".

Ngenxa yeenzuzo zengingqi, umzi-mveliso wethu unendawo enkulu kunye nezixhobo zokudubula iimveliso.Sisebenzisa izitofu zetonela ukuvelisa.Ixesha lokudubula lide.I-glaze, iglosi, kunye nokuzinza kwe-thermal zingcono kunezo zisetyenziswa kwiifektri ezincinci eziqhelekileyo I-roller kiln ingcono kakhulu.

Ngelo xesha, imveliso ye-tunnel kiln iqhubeka ngakumbi, umjikelezo mfutshane, imveliso inkulu, kwaye umgangatho uphezulu.Isebenza ngomgaqo ophikisanayo, ngoko izinga lokusetyenziswa kobushushu liphezulu, kwaye i-fuel iyonga.Kuba ukugcinwa kobushushu kunye nokusetyenziswa kobushushu benkunkuma kulungile, i-fuel iyonga kakhulu.Xa kuthelekiswa ne-inverted flame kiln, inokonga malunga ne-50-60% yamafutha.ukuphuculwa komgangatho.Ukushisa kwamacandelo amathathu ommandla wokushisa, indawo yokudubula kunye nommandla wokupholisa zihlala zigcinwa ngaphakathi kwinqanaba elithile, okwenza kube lula ukuqonda umthetho wokudubula, ngoko ke umgangatho ungcono kwaye izinga lomonakalo lincinci.
