Kaolin bụ mineral na-abụghị ọla, nke bụ ụdị ụrọ na nkume ụrọ nke nwere mineral ụrọ nke Kaolinite.N'ihi ọdịdị ọcha ya na nke siri ike, a na-akpọkwa ya ala Baiyun.Aha ya bụ obodo Gaoling dị na Jingdezhen, Jiangxi Province.

Kaolin ya dị ọcha dị ọcha, dị nro na Mollisol dị ka, nwere ezigbo plasticity, ọkụ ọkụ na ihe ndị ọzọ anụ ahụ na kemịkal.Ihe mejupụtara ya bụ Kaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar na mineral ndị ọzọ.A na-eji Kaolin eme ihe n'ọtụtụ ebe n'ime mpempe akwụkwọ, ceramik, na ihe ndị na-agbagharị agbagharị, na-esote mkpuchi, ihe mkpuchi rọba, glazes enamel, na ngwa ciment ọcha.A na-eji obere ego eme ihe na rọba, agba, pigmenti, wiil egweri, pensụl, ihe ịchọ mma kwa ụbọchị, ncha, pesticides, ọgwụ, textiles, mmanụ ala, kemịkalụ, ihe owuwu ụlọ, nchekwa mba, na ngalaba mmepụta ihe ndị ọzọ.
