Lub luag haujlwm ntawm cov neeg sab nrauv carbonate hauv glue: fruit yog pre-smelt cov khoom siv raw lossis dhau los ua lub khob iav, uas yog ib qho uas siv tau flux raw khoom rau cerum greatam. Thaum ua ntej-smelted rau hauv flux, feem ntau ntawm cov roj tuaj yeem raug tshem tawm cov khoom ci, yog li txo cov khoom ntawm npuas thiab cov qhov me me ntawm cov kab ceramic ci. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov khoom sib xyaw ua ke nrog kev kub siab thiab kev tua neeg luv luv, xws li Ceramics Txhua Hnub thiab Kev Kho Kom Huv Si.
Cov kib yog tam sim no dav siv hauv kev ua haujlwm nrawm-tua hluav taws Vim hais tias ntawm nws qhov qis qis melting kub thiab hluav taws kub kub kub ntau, fruit muaj lub luag haujlwm irreplacleable Rau cov plooj (porcelain nrog kev kub siab dua txias, cov khoom siv raw yog ib txwm siv los ua lub ntsej muag loj. Txawm hais tias Frit yog siv rau lub ntsej muag ci, tus nqi ntawm frit yog qhov me me (tus nqi ntawm frit hauv lub ci yog tsawg dua 30%.).
Cov hmoov txhuas tsis muaj tshuaj tsw qab nyob rau qhov chaw ua teb ntawm Frit ci rau cov ceramics. Nws yog ua los ntawm cov ntaub ntawv raw hauv qab no: 15-30% ntawm quartz, 30-50 ntawm boric acid, 3-6% ntawm stalactite. 12%, Zinc Oxide 3-6%, Strackium Carbonate 2-5%, Lithium Carbonate 2-4%, slaked talc 2-8%. Ua tiav cov thawj coj ntawm cov hmoov txhuas tuaj yeem ntsib cov neeg xav tau kev noj qab haus huv thiab muaj txiaj ntsig zoo ceramics.
