Tom qab cov khoom yog glazed, peb muab cov khoom tso rau hauv qhov cub rau kev tua hluav taws ua ntej.Tshuab cov plua plav ceramic ua ntej tua tuaj yeem txhim kho cov txiaj ntsig ntawm cov khoom.Cov plua plav ntawm qhov chaw ntawm cov khoom raug tshem tawm, thiab nws tsis yooj yim rau cov khoom tsim cov khoom.

Kev tua hluav taws yog txheej txheem tseem ceeb heev hauv kev tsim cov ceramic.Tom qab ua kom zoo li tus thiab glazed, cov khoom ib nrab tsuas tuaj yeem dhau los ua cov tshuaj tiv thaiv lub cev thiab tshuaj lom neeg nyob rau hauv qhov kev txiav txim ntawm qhov kub thiab txias, thiab thaum kawg qhov pom meej porosity yog ze rau xoom, thiaj li ua tiav qhov ntom ntom ntawm cov plooj (porcelain).Cov txheej txheem no hu ua "firing".

Vim yog lub regional zoo, peb lub Hoobkas muaj qhov chaw loj dua thiab cov khoom siv hluav taws xob tua hluav taws.Peb siv tunnel kilns rau ntau lawm.Lub sijhawm tua yog ntev dua.Lub glaze, gloss, thiab thermal stability yog zoo dua li cov uas siv nyob rau hauv dog dig me me factories Cov menyuam kiln yog zoo dua.

Nyob rau tib lub sijhawm, tunnel kiln ntau lawm ntau nruam, lub voj voog luv dua, cov zis ntau dua, thiab qhov zoo dua.Nws ua haujlwm los ntawm cov ntsiab lus countercurrent, yog li qhov kev siv hluav taws xob kub yog siab, thiab cov roj yog kev lag luam.Vim tias cov cua kub tuav thiab kev siv hluav taws xob pov tseg yog qhov zoo, cov roj siv tau zoo heev.Piv nrog rau cov hluav taws kub hloov pauv, nws tuaj yeem txuag tau li 50-60% ntawm cov roj.kev txhim kho zoo.Qhov kub ntawm peb qhov chaw ua ntej cua sov, qhov chaw tua hluav taws thiab qhov chaw txias yog feem ntau khaws cia rau hauv ib qho chaw, uas ua rau nws yooj yim los tuav txoj cai tua hluav taws, yog li qhov zoo kuj tseem zoo dua thiab qhov kev puas tsuaj tsawg dua.
