Kaolin ni amabuye y'agaciro atari icyuma, akaba ari ibuye ry'ibumba n'ibumba rigizwe ahanini n'amabuye y'ibumba ya kaolinite. Bitewe n'uko isa n'umweru kandi yoroshye, izwi kandi nk'ubutaka bwa Baiyun. Yitiriwe Umudugudu wa Gaoling muri Jingdezhen, Intara ya Jiangxi.

Kaolin yayo nziza ni umweru, yoroshye kandi yoroshye mu miterere yayo, ifite imiterere myiza y’umubiri n’imiti nko kuba plastike no kwirinda umuriro. Ibigizemo imyunyu ngugu igizwe ahanini n’imyunyu ngugu nka kaolinite, halloysite, hydromica, illite, montmorillonite, ndetse na quartz na feldspar. Kaolin ikoreshwa cyane mu gukora impapuro, ibumba, n’ibikoresho birwanya ubushyuhe, hagakurikiraho irangi, irangi rya rubber, glaze za enamel, n’ibikoresho fatizo bya sima yera. Ingano nto ikoreshwa muri pulasitiki, amarangi, amarangi, amapine, amapine yo gusya, amakaramu, amavuta yo kwisiga ya buri munsi, isabune, imiti yica udukoko, imyenda, peteroli, imiti, ibikoresho by’ubwubatsi, ubwubatsi bw’igihugu, n’izindi nganda.

Imyunyungugu iri muri kaolini mu bidukikije igabanyijemo ibice by’imyunyungugu y’ibumba n’imyunyungugu itari ibumba. Imyunyungugu y’ibumba igizwe ahanini n’imyunyungugu ya kaolinite hamwe n’ingano nto ya montmorillonite, mica, na chlorite; Imyunyungugu itari ibumba igizwe ahanini na feldspar, quartz, na hydrates, ndetse n’imyunyungugu imwe n’imwe y’icyuma nka hematite, siderite, limonite, titanium nka rutile, n’ibintu bikomoka ku bimera nk’imigozi y’ibimera. Ikintu cy’ingenzi kigena imikorere ya kaolini ni imyunyungugu y’ibumba.

Kaolin yabaye amabuye y'agaciro y'ingenzi ku nganda nyinshi nko gukora impapuro, ibumba, kabutura, ubukanishi bw'imiti, irangi, imiti, no kurinda igihugu.

Inganda zikora ibumba ni zo nganda za mbere kandi zikoreshwa cyane mu gukoresha kaolin. Igipimo rusange ni 20% kugeza 30% by'ibumba. Akamaro ka kaolin mu ibumba ni ugushyiramo Al2O3, ifite akamaro mu gukora mullite, ikongera ubushobozi bwayo bwo gushonga no gushonga. Mu gihe cyo gushonga, kaolin irabora igakora mullite, igakora urufatiro rw'ingenzi rw'imbaraga z'umubiri. Ibi bishobora gukumira guhindagurika kw'ibicuruzwa, kongera ubushyuhe bwo kurasa, ndetse no guha umubiri urwego runaka rw'umweru. Muri icyo gihe, kaolin ifite urugero runaka rwa plasticity, gufatana, guhagarara, no gushobora gufatana, iha ibumba rya porcelain n'ibumba ubushobozi bwo gukora neza, bigatuma umubiri w'ibumba rya porcelain urushaho kuba mwiza, bigatuma umubiri w'ibumba rya porcelain urushaho kuba mwiza ku mubiri w'imodoka no kugabanya ubushyuhe, bigatuma byoroha gukora. Iyo ikoreshejwe mu nsinga, ishobora kongera ubushyuhe no kugabanya igihombo cya dielectric.

Ibikoresho bya Ceramics ntibifite gusa ibisabwa kugira ngo bigire plastike, bifatanye, bibe bito, bibe bito, bibe bito, bibe bito, birwanya umuriro, kandi bibe bito, ahubwo binagira imiterere ya shimi, cyane cyane ko hari ibintu bya chromogenic nka fer, titanium, umuringa, chromium, na manganese, bigabanya ubwiza nyuma yo gushya kandi bigatanga utudomo.

Igisabwa ku bunini bw'uduce twa kaolini muri rusange ni uko utubuto tworoshye ari two twiza, kugira ngo icyondo cya porcelain kigire ubuziranenge bwiza n'imbaraga zo kumisha. Ariko, ku bikorwa byo gusuka bisaba gusuka vuba, umuvuduko wo gusya wihuta, n'umuvuduko wo kubura amazi, ni ngombwa kongera ingano y'uduce tw'ibikoresho. Byongeye kandi, itandukaniro mu buziranenge bwa kaolinite muri kaolini naryo rizagira ingaruka zikomeye ku mikorere y'uduce twa porcelain. Niba ubuziranenge ari bwiza, ubuziranenge n'ubushobozi bwo gufatanya biri hasi, ubushyuhe bwo kumisha ni buto, ubushyuhe bwo kumisha ni bwinshi, kandi ubuziranenge bw'umwanda nabwo buragabanuka; Ibinyuranye n'ibyo, ubuziranenge bwayo buri hejuru, ubushyuhe bwo kumisha ni bwinshi, ubushyuhe bwo kumisha ni buke, kandi ubuziranenge bw'umwanda nabwo buri hejuru.
