Kaolin ndi mchere sanali zitsulo, amene ndi mtundu wa dongo ndi dongo thanthwe makamaka wopangidwa ndi gulu Kaolinite dongo mchere.Chifukwa cha mawonekedwe ake oyera komanso osalimba, amadziwikanso kuti dothi la Baiyun.Amatchedwa mudzi wa Gaoling ku Jingdezhen, m'chigawo cha Jiangxi.

Kaolin wake woyera ndi woyera, wosakhwima ndi Mollisol ngati, ndi pulasitiki wabwino, kukana moto ndi zina thupi ndi mankhwala katundu.Mapangidwe ake amchere amapangidwa makamaka ndi Kaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar ndi mchere wina.Kaolin amagwiritsidwa ntchito kwambiri popanga mapepala, ziwiya zadothi, ndi zomangira, zotsatiridwa ndi zokutira, zodzaza mphira, zowulira enamel, ndi zida zoyera za simenti.Zochepa zimagwiritsidwa ntchito mu pulasitiki, utoto, inki, mawilo opera, mapensulo, zodzoladzola za tsiku ndi tsiku, sopo, mankhwala ophera tizilombo, mankhwala, nsalu, mafuta, mankhwala, zomangira, chitetezo cha dziko, ndi mafakitale ena.

Mchere wa Kaolin amapangidwa ndi Kaolinite, dickite, miyala ya ngale, halloysite ndi mchere wina wamagulu a Kaolinite, ndipo gawo lalikulu la mchere ndi Kaolinite.

Njira ya Crystal chemistry ya Kaolinite ndi 2SiO2 ● Al2O3 ● 2H2O, ndipo kapangidwe kake ka Theoretical chemistry ndi 46.54% SiO2, 39.5% Al2O3, 13.96% H2O.Kaolin mchere ndi 1: 1 mtundu wosanjikiza silicate, ndi krustalo makamaka wapangidwa silika tetrahedron ndi aluminiyamu Octahedron.Silica tetrahedron imalumikizidwa motsatira njira ya mbali ziwiri pogawana ngodya ya vertex kuti ipange gululi la hexagonal, ndipo mpweya wapamwamba womwe sunagawidwe ndi tetrahedron uliwonse wa silika umayang'ana mbali imodzi;Mtundu wa 1: 1 unit wosanjikiza umapangidwa ndi silicon oxide tetrahedron wosanjikiza ndi aluminium oxide Octahedron wosanjikiza, yomwe imagawana nsonga ya okosijeni wa silicon oxide tetrahedron wosanjikiza.
