Koj puas paub tias cov xim ntawm cov nplais ceramic yog tsim li cas?

Koj yuav tsum tau pom ceramics ntawm ntau yam duab thiab xim.Txawm li cas los xij, koj puas paub vim li cas ceramics tuaj yeem nthuav tawm txhua yam xim zoo nkauj?

Qhov tseeb, ceramics feem ntau muaj glossy thiab du "glaze" ntawm lawv qhov chaw.

Glaze yog ua los ntawm cov ntxhia raw cov ntaub ntawv (xws li feldspar, quartz, kaolin) thiab tshuaj raw cov ntaub ntawv sib tov nyob rau hauv ib tug tej yam ratio thiab finely av rau slurry kua, siv rau saum npoo ntawm ceramic lub cev.Tom qab qee qhov kub ntawm calcining thiab melting, thaum qhov kub thiab txias poob, tsim cov iav nyias txheej rau ntawm qhov chaw ntawm cov ceramic.

Thaum ntxov li 3000 xyoo dhau los, cov neeg Suav twb tau kawm siv pob zeb thiab av nkos los ua glazes rau decorate ceramics.Tom qab ntawd, cov kws kos duab ceramic tau siv qhov tshwm sim ntawm kiln tshauv poob rau ntawm lub cev ceramic los ua glaze, thiab tom qab ntawd siv cov ntoo tshauv los ua cov khoom siv rau glaze.

Lub glaze siv nyob rau hauv cov niaj hnub niaj hnub ceramics yog muab faib ua txiv qaub glaze thiab feldspar glaze.Lime glaze yog tsim los ntawm glaze pob zeb (ib yam khoom ntxhia raw khoom) thiab txiv qaub-flyash (lub ntsiab tivthaiv yog calcium oxide), thaum feldspar glaze yog feem ntau yog tsim los ntawm quartz, feldspar, marble, kaolin, thiab lwm yam.

Ntxiv cov hlau oxides lossis infiltrating lwm yam tshuaj lom neeg rau hauv cov txiv qaub glaze thiab feldspar glaze, thiab nyob ntawm qhov kub kub, ntau yam xim glaze tuaj yeem tsim.Muaj cyan, dub, ntsuab, daj, liab, xiav, ntshav, thiab lwm yam.White porcelain yog ib tug ze li ntawm tsis muaj xim pob tshab glaze. Feem ntau, lub thickness ntawm ceramic lub cev glaze yog 0.1 centimeters, tab sis tom qab tau calcined nyob rau hauv lub kiln, nws yuav. nruj me ntsis ua raws li cov plooj (porcelain) lub cev, uas ua rau cov plooj (porcelain) ntom ntom, glossy, thiab mos, tsis yog impermeable rau dej los yog tsim npuas, muab tib neeg lub siab zoo li daim iav.Nyob rau tib lub sijhawm, nws tuaj yeem txhim kho kev ua haujlwm ntev, tiv thaiv kev ua qias tuaj, thiab ua kom yooj yim ntxuav.
