Glaze yog txheej txheej zoo nkauj ntawm ceramics, qee qhov yooj yim thiab qee qhov muaj xim zoo nkauj. Raws li ib yam ntawm cov iav txheej rau saum npoo ntawm ceramics, nws muaj qhov nqus dej tsawg, cov khoom siv tshuaj ruaj khov, thiab cov glaze hardness siab, uas ua rau cov ceramics ruaj khov, yooj yim los ntxuav thiab ntxuav, thiab tiv taus acid, alkali, thiab ntsev corrosion. .
Nws yog qhov tseeb vim tias txheej glaze plays lub luag haujlwm tseem ceeb uas cov txheej txheem glazing tau yog ib feem tseem ceeb ntawm cov txheej txheem ua cov plooj (porcelain) txij thaum ub los txog rau tam sim no!
Muaj ntau hom ceramic glazes. Raws li qhov muaj pes tsawg leeg ntawm glaze, nws tuaj yeem muab faib ua txiv qaub glaze, feldspar glaze, thiab lwm yam; raws li qhov kub thiab txias, nws tuaj yeem muab faib ua qhov kub thiab txias glaze; Raws li cov tsos mob tom qab tua, nws tuaj yeem muab faib ua pob tshab glaze, opalescent glaze, xim glaze, glossy glaze, matte glaze, siv lead ua glaze, iav glaze, crackle glaze, kiln-hloov glaze, thiab lwm yam. thiab tseem muaj ntau txoj hau kev glazing, xws li dipping glaze, pouring glaze, spraying glaze, swinging glaze, txhuam glaze, thiab lwm yam.
Dipping glaze
Dip glaze muaj qhov zoo ntawm kev txuag lub sijhawm thiab kev ua haujlwm yooj yim. Muaj ob hom glazing: immersing tag nrho lub cev ntawm lub nkoj nyob rau hauv lub glaze tank thiab glazing txheej glaze ntawm lub nkoj. Tag nrho lub cev dipping glaze feem ntau haum rau glazing cov khoom me me. Cov khoom me me no yooj yim dua los tuav thiab tswj, yog li dipping glaze ib zaug txaus. Txawm li cas los xij, tej hauj lwm loj txawv. Nws yuav tsum tau muab sau tseg tias txheej txheem glazing rau cov khoom loj yog siv lub puab glaze ua ntej thiab tom qab ntawd cov txheej glaze. Vim hais tias ib zaug txheej glaze yog adsorbed ntawm cov khoom, nws yuav sai sai qhuav rau hauv cov hmoov thiab tsis tuaj yeem kov dua, txwv tsis pub cov glaze txheej yuav raug rhuav tshem thiab deglazing yuav tshwm sim tom qab tua. Ua ntej siv cov glaze sab nrauv, koj yuav tsum xyuas kom meej tias cov glaze sab hauv yog qhov pib qhuav, yog li ntawd cov khoom yuav rov ua dua thiab nqus cov glaze slurry.
Thaum cov glaze sab hauv qhuav, tus kws ua haujlwm tuav qhov tsim nyog ntawm lub nkoj nrog ob txhais tes, ua ntej yaug hauv qab ntawm lub nkoj hauv ib lub phiab dej huv kom txo qis glaze nqus dej hauv qab, thiab tom qab ntawd nias tag nrho cov hlab ntsha mus rau hauv lub phiab. glaze tank nrog lub zog. Thaum lub sij hawm nias thiab dipping txheej txheem, ua tib zoo saib xyuas kom lub glaze slurry nto theem nrog lub qhov ncauj ntawm lub nkoj, thiab tsis txhob cia lub glaze slurry hla lub ntug ntawm lub nkoj thiab ntws mus rau hauv lub nkoj kom tsis txhob glazing.
Glaze dipping yog txheej txheem txuas ntxiv. Lub sijhawm dipping yog txiav txim siab raws li qhov loj thiab tuab ntawm cov khoom. Nws feem ntau siv 10 mus rau 20 vib nas this lossis ntev dua. Thaum lub dipping tiav lawm, tshem cov khoom tawm thiab sim tig nws kom nws nqus cov glaze sib npaug. Qhov no ua tiav cov txheej txheem dipping.
swinging glaze
Swinging glaze yog hais txog ib txoj kev glazing sab hauv ntawm lub nkoj (hu ua " puab glaze"), uas feem ntau yog siv rau cov hlab ntsha sib sib zog nqus thiab lub qhov ncauj me me xws li hub, fwj, thiab urns ( tais, phaj, tais diav, thiab lwm yam). . nrog qhov qhib loj tuaj yeem dipped hauv glaze ib zaug). Cov txheej txheem yog siv ib rab diav los txhaj cov glaze slurry rau hauv lub nkoj, sau txog ib nrab ntawm qhov chaw hauv lub nkoj, thiab tom qab ntawd nqa lub nkoj thiab co nws ntawm qhov nrawm kom ua rau cov glaze slurry hauv lub nkoj dai tusyees ntawm lub nkoj. phab ntsa. Yog tias lub nkoj loj dhau lawm, nws yuav tsum muaj ob tus neeg ua haujlwm ua ke, thiab kev txav ntawm ob tus neeg yuav tsum tau sib dhos. Sab hauv glaze feem ntau tsis tas yuav tsum yog tuab heev. Thaum nws nce mus txog qhov yuav tsum tau ua kom tuab, ncuav tawm qhov seem glaze slurry thiab glazing tiav.
Txhuam glaze
Txhuam glaze, tseem hu ua "glazing", yog siv cov txhuam hniav los txhuam cov glaze slurry thiab siv rau ntawm qhov khoob. Txoj kev no tau pom thawj zaug hauv cov plooj (porcelain) ntawm Qin thiab Han dynasties. Nws feem ntau yog siv rau cov khoom angular, lossis rau ib nrab glazing thiab glazing ntawm lub qhov ncauj, lub xub pwg nyom, hauv qab, thiab lwm yam, nrog rau siv ob peb glazes sib txawv ntawm tib yam dawb paug.
Txau glaze
Txau glaze tseem hu ua tshuab glaze. Cov txheej txheem glaze txau yog tsuas yog ua kom cov tuab ntawm txheej glaze thiab ua rau lub thickness txwv ntawm lub cev absorbing glaze thaum lub sij hawm glazing txheej txheem. Txau glaze yuav tsum yog kauj ruam kawg hauv txheej txheem glazing. Lub thickness ntawm glaze txheej yuav tsum tau nce nyob rau hauv lub hauv paus ntawm kom ntseeg tau lub flatness ntawm glaze nto. Yog li ntawd, txoj kev no tso lub lauj kaub tais diav rau glazed ntawm lub turntable. Thaum tus kws tsim khoom siv lub tshuab tig tsis tu ncua, nws txau cov glaze slurry ncaj qha rau ntawm lub lauj kaub tais diav nrog lub sprayer, thiab glaze nto ntawm glazing yav dhau los yog qhov pib qhuav ua ntej txau cov glaze dua.
Pouring glaze & ncuav glaze
Glazing glaze tuaj yeem tsim cov nyhuv tshwj xeeb nrog kev nkag siab ntawm kev ntws. Nws yog ib txoj kev glazing dav siv los ntawm peb cov poj koob yawm txwv, tshwj xeeb tshaj yog nyob rau hauv peb-xim glaze ntawm Tang Dynasty. Craftsmen feem ntau ncuav ob peb xim txawv glazes ntawm lub lauj kaub tais diav, los yog siv cov txheej txheem ntawm splashing, los yog siv txawv thicknesses ntawm glaze txheej, los yog ncuav me me hais ntawm unground porcelain pob zeb nyob rau hauv glaze nto ntawm lub cev los tsim ib tug zoo li lub hnub qub nyhuv, yog li tsim kom muaj kev txaus siab tshwj xeeb.
Lub log glaze
Log glaze feem ntau yog siv rau cov khoom tiaj tus xws li daim hlau thiab cov tais diav. Lub cev yog muab tso rau ntawm ib tug rotating windlass laub. Thaum nws tig, tus kws tsim khoom siv lub tais los yog rab diav los rub lub glaze slurry thiab ncuav rau hauv nruab nrab ntawm lub cev. Vim yog lub zog centrifugal, lub glaze slurry yog sib npaug, yog li cov khoom yog glazed nrog ib tug tuab tuab, thiab ntau glaze slurry yog pov tawm ntawm lub cev. Hais lus nruj me ntsis, lub log glaze yog ib hom pouring glaze.
