I-Kaolin iyiminerali engeyona eyensimbi, okuwuhlobo lwedwala lobumba nobumba oluhlanganiswe kakhulu ngamaminerali obumba eqembu le-Kaolinite. Ngenxa yokubukeka kwayo okumhlophe nokuthambile, yaziwa nangokuthi inhlabathi ye-Baiyun. Iqanjwe ngegama leGaoling Village eJingdezhen, eSifundazweni saseJiangxi.

I-kaolin yayo emsulwa imhlophe, ithambile futhi ifana ne-Mollisol, ine-plasticity enhle, ukumelana nomlilo kanye nezinye izakhiwo zomzimba nezamakhemikhali. Ukwakheka kwayo kwamaminerali kwakhiwe kakhulu yi-Kaolinite, i-halloysite, i-hydromica, i-Illite, i-Montmorillonite, i-quartz, i-feldspar kanye nezinye izimbiwa. I-Kaolin isetshenziswa kabanzi ekwenzeni iphepha, izinto zobumba, nezinto eziphikisayo, kulandelwa ukumbozwa, izigcwalisi zerabha, ama-enamel glaze, kanye nezinto zokusetshenziswa zesimende esimhlophe. Inani elincane lisetshenziswa kupulasitiki, upende, imibala, amasondo okugaya, amapensela, izimonyo zansuku zonke, insipho, izibulala-zinambuzane, imithi, izindwangu, uphethiloli, amakhemikhali, izinto zokwakha, ukuvikela izwe, kanye neminye imikhakha yezimboni.

Amaminerali e-Kaolin akhiwa yi-Kaolinite, i-dicte, itshe leparele, i-halloysite kanye namanye amaminerali e-Kaolinite cluster, kanti ingxenye eyinhloko yamaminerali yi-Kaolinite.

Ifomula ye-Crystal chemistry ye-Kaolinite ingu-2SiO2 ● Al2O3 ● 2H2O, kanti ukwakheka kwayo kwe-Theoretical chemistry kungu-46.54% SiO2, 39.5% Al2O3, 13.96% H2O. Amaminerali e-Kaolin angaphansi kwe-silicate enezingqimba zohlobo lwe-1:1, kanti i-crystal yakhiwe kakhulu yi-silica tetrahedron kanye ne-alumina Octahedron. I-silica tetrahedron ixhunywe ohlangothini olunezinhlangothi ezimbili ngokwabelana nge-engeli ye-vertex ukuze kwakhiwe ungqimba lwegridi olunezinhlangothi eziyisithupha, kanti i-oxygen ephezulu engahlanganyelwa yi-silica tetrahedron ngayinye ibheke ohlangothini olulodwa; Ungqimba lweyunithi yohlobo lwe-1:1 lwakhiwe ungqimba lwe-silicon oxide tetrahedron kanye nongqimba lwe-aluminium oxide Octahedron, oluhlanganyela i-oxygen engenhla yongqimba lwe-silicon oxide tetrahedron.
