Tom qab tsim cov khoom tsim tiav thiab kev tua hluav taws ua tiav, vim yog cov txheej txheem firing ceramic, daim duab yuav hnav thiab glaze puas vim muaj ntau yam laj thawj.Zoo ib yam li cov pores me me, khoom deformation, thiab lwm yam teeb meem.Lub sijhawm no, peb yuav tsum xaiv tag nrho cov khoom los ntawm kev xaiv phau ntawv.Xyuas kom meej tias cov nyhuv ntawm cov khoom tseem zoo ib yam.Vim muaj kev txwv ntawm cov khoom siv ceramic, cov khoom tsis tiav ceramic yog qhov nyuaj rau kev xaiv los ntawm cov tshuab.Peb tshuaj xyuas cov khoom tsis tiav los ntawm kev siv tes ua haujlwm nrog ntau xyoo ntawm kev xaiv.

Hauv cov txheej txheem xaiv, peb yuav tsum nkag siab txog cov laj thawj rau qhov zoo ntawm cov plooj (porcelain).Cov tsos zoo ntawm cov plooj (porcelain) nyob ntawm qhov gloss, whiteness, chromatic aberration thiab cov nyhuv ntawm cov khoom nto.Hauv kev xaiv cov txheej txheem, cov neeg xaiv yuav tshuaj xyuas cov khoom siv hauv lub rooj noj mov raws li qhov yuav tsum tau ua ntawm cov khoom siv rooj noj mov, thiab xaiv cov tais diav uas tsis ua raws li cov khoom siv.Omissions yooj yim tshwm sim hauv cov txheej txheem no.Lub sijhawm no, cov neeg muag khoom lag luam yuav tsum tau ua kev tshuaj ntsuam xyuas ntxiv kom ntseeg tau tias cov khoom zoo sib xws.Xa ntau cov khoom zoo rau cov neeg siv khoom.
