Kazhinji, zvigadzirwa zvegirazi zvinopiswa pakupisa kwakanyanya kwe1400 ~ 1300 ℃.Kana girazi riri mumamiriro emvura, mhepo iri mariri yakayangarara kubva pamusoro, saka kune mashoma kana kusavapo.Nekudaro, mazhinji eakakandirwa magirazi emifananidzo anopfurwa pane yakaderera tembiricha ye850 ℃, uye inopisa girazi paste inoyerera zvishoma nezvishoma.Mhepo iri pakati pemagirazi egirazi haigone kuyangarara kunze kwepamusoro uye inoumba mabhuru.Vanyori vanowanzoshandisa mabubble kuratidza hupenyu hwegirazi uye kuva chikamu chekukoshesa girazi art.
