Kaolin o se minerale e le o u'amea, o se ituaiga o omea ma ma'a omea e masani ona aofia ai minerale omea vaega Kaolinite.Ona o lona paʻepaʻe ma foliga maaleale, ua lauiloa foi o le eleele Baiyun.E faaigoa i le Gaoling Village i Jingdezhen, Jiangxi Province.

O lona kaolin mama e paʻepaʻe, maʻaleʻale ma Mollisol pei, faʻatasi ai ma le palasitika lelei, faʻamaʻi afi ma isi mea faʻapitoa ma vailaʻau.O lona tuufaatasiga minerale e masani lava ona aofia ai Kaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar ma isi minerale.O le Kaolin e masani ona faʻaaogaina i le gaosiga o pepa, sima, ma mea e faʻafefeteina, sosoo ai ma mea faʻapipiʻi, faʻapipiʻi paʻu, faʻamalama faʻamalama, ma mea paʻepaʻe sima.O se vaega itiiti e faʻaaogaina i palasitika, vali, lanu, uili olo, penitala, mea teuteu i aso uma, fasimoli, vailaʻau faʻamaʻi, vailaʻau, ie, suauu, vailaʻau, mea fau fale, puipuiga a le atunuʻu, ma isi vaega o pisinisi.

O minerale Kaolin e aofia ai le Kaolinite, dickite, penina ma'a, halloysite ma isi minerale fuifui Kaolinite, ma o le vaega autu o minerale o le Kaolinite.

Ole fua ole kemisi Crystal o Kaolinit ole 2SiO2 ● Al2O3 ● 2H2O, ma lona Theoretical chemistry composition o 46.54% SiO2, 39.5% Al2O3, 13.96% H2O.O minerale Kaolin e aofia i le 1: 1 type layered silicate, ma o le tioata e masani lava ona aofia ai le silica tetrahedron ma alumina Octahedron.O le silica tetrahedron e fesoʻotaʻi i le itu e lua-dimensional e ala i le faʻasoaina o le vertex angle e fausia ai se faʻasologa o le hexagonal grid, ma o le maualuga o le okesene e le faʻasoa e silica tetrahedron taʻitasi e faʻasaga i le tasi itu;O le 1:1 type unit layer e aofia ai le silicon oxide tetrahedron layer ma alumini oxide Octahedron layer, lea e fa'asoa ai le pito o le okesene o le silicon oxide tetrahedron layer.
