Cov txheej txheem ntau lawm ntawm iav jars

Lub khob iav yog lub thawv ntim tshuaj uas nquag siv hauv ntim khoom noj, ntim khoom plig, thiab ntim tshuaj.
Iav hub txheej txheem ntau lawm:
Cov txheej txheem iav hub feem ntau suav nrog, raw khoom ua ntej. Sib tsoo cov khoom siv raw (quartz xuab zeb, dej qab zib tshauv, limestone, feldspar, thiab lwm yam), qhuav ntub cov ntaub ntawv raw, thiab tshem tawm cov hlau los ntawm cov hlau uas muaj cov khoom siv raw los xyuas kom cov iav zoo. Batch npaj thiab melting. Cov iav batch khoom yog rhuab nyob rau hauv lub pas dej ua ke kiln los yog pas dej ua ke rauv ntawm qhov kub ntawm 1550 ~ 1600 degrees los tsim ib tug uniform, npuas-dawb kua iav uas ua tau raws li qhov yuav tsum tau molding. Muab cov iav ua kua rau hauv pwm los ua cov khoom iav ntawm cov khoom uas yuav tsum tau ua, xws li cov phaj tiaj tiaj, ntau yam tais diav, thiab lwm yam rau kev kho cua sov. Los ntawm annealing, quenching thiab lwm yam txheej txheem, tshem tawm los yog ua kom muaj kev ntxhov siab, theem kev sib cais los yog crystallization hauv iav, thiab hloov cov txheej txheem ntawm lub khob.
Cov hub iav feem ntau yog siv rau hauv ntim khoom noj, ntim khoom plig, ntim tshuaj, thiab cov khoom siv tshuaj.
