Ceramic mugs feem ntau yog tsim los ntawm cov zaub mov xws li kaolin thiab quartz; lawv raug rho tawm haujlwm ntawm qhov kub siab (feem ntau siab dua 1,200 degree) los tsim cov qauv ntom ntom.
Lub siab -kub tsis kam ntawm ceramic mugs stems los ntawm lub hauv paus chiv keeb ntawm lawv cov ntaub ntawv. Thaum lub sij hawm siab - kub hnyiab, kaolin forms mullite crystals- ib tug qauv muaj peev xwm tiv taus qhov kub thiab txias hloov ceev (feem ntau yog li ntawm -20℃mus rau 150 degree) yam tsis yooj yim tawg. Lub glazed nto seals cov khoom lub pores, tiv thaiv cov kua nkag.
Hais txog kev nyab xeeb, cov khoom raug cai yuav tsum xeem dhau kev ntsuas kev nyab xeeb rau zaub mov- cov ntaub ntawv tiv tauj (xws li GB 4806.4-2016 tus qauv) kom ntseeg tau tias cov qib leaching ntawm cov hlau hnyav xws li txhuas thiab cadmium nyob hauv qhov txwv tsis pub muaj kev nyab xeeb. Thaum siv, tsis txhob tso cua sov lub khob thaum khoob lossis nthuav tawm ncaj qha mus rau qhov qhib nplaim taws kom tsis txhob muaj kev puas tsuaj rau glaze.
