Ma glaze oyera, omwe nthawi zambiri amadalira silika ngati chinthu chachikulu chopangira magalasi pamodzi ndi ma fluxes (monga feldspar kapena borax) kuti achepetse kutentha kosungunuka ndi mitundu (monga zitsulo zosungunuka zamitundu inayake) ya mtundu, nthawi zambiri amavutika kuti akwaniritse kuchuluka koyenera kapena koyenera kwa gloss - nkhani zomwe zimakhudza mwachindunji mtundu wa malonda ndi kugulitsidwa. Mavuto awa si okongoletsa okha; gloss yosagwirizana yokhala ndi matte patches ingapangitse kuti zidutswa zofanana za tebulo ziwoneke ngati zosafanana, zomwe zimachepetsa kukongola kwawo kwa ogulitsa ndi ogula. Mawonekedwe osawoneka bwino samawonetsa mtundu wapamwamba, zomwe zimakankhira zinthu m'magawo otsika mtengo ngakhale thupi la ceramic palokha lili lapamwamba. Kusawoneka bwino kumakhala kovuta makamaka pa zokongoletsa za ceramic ndi zinthu zaukhondo, komwe kutsirizika kofanana ndikofunikira kwambiri pakugwirizana kwa mawonekedwe. Zomwe zimayambitsa mavutowa ndi zambiri: kufalikira kwa tinthu tating'onoting'ono kumachitika pamene zigawo za glaze sizisakanikirana mofanana, zomwe zimapangitsa kuti pakhale matumba okhuthala a mitundu kapena ma fluxes omwe amasungunuka mosiyana. Kuchulukana kwa zigawo za glaze - zomwe zimakhala ndi tinthu tating'onoting'ono tomwe tili ndi mphamvu yayikulu pamwamba - kumapanga magulu ang'onoang'ono omwe amakana kusungunuka, ndikusiya malo ovuta pamwamba. Kusakanikirana kosakwanira, komwe nthawi zambiri kumachitika chifukwa cha kutentha kosakwanira (komwe kuli pansi pa mulingo woyenera wa zigawo za glaze) kapena kuchuluka kosalinganika kwa flux (kochepa kwambiri kuti kusungunuke kwathunthu kapena kochuluka kwambiri komwe kumayambitsa kutuluka kwa madzi ambiri), kumasiya silika yosasinthika kapena tinthu tamitundu yosiyanasiyana tomwe timayikidwa mu glaze. Tinthu tosasinthikati timasokoneza kusalala, kutulutsa kuwala m'malo molola kuti kuwonekere mofanana, zomwe zimapangitsa kuti kuwalako kuwonekere bwino, kopanda madontho kapena kopanda kuwala komwe sikukwaniritsa miyezo yamakampani.

Ufa wa Kaolin umathetsa mavuto akuluakuluwa kudzera mu mawonekedwe ake apadera, kuyambira ndi kapangidwe kake kakang'ono kwambiri, kofanana ndi mbale komwe kamakhala pakati pa ma micrometer angapo mpaka ma micrometer ochepa—kofewa kwambiri kuposa zodzaza zina zambiri za ceramic. Pakusakaniza glaze, tinthu tofanana ndi mbale timagwira ntchito ngati "zothandiza kufalikira," kulekanitsa zigawo zomangira monga utoto ndi silika poziyika pakati pa ma aggregates. Izi zimaonetsetsa kuti dera lililonse la glaze lili ndi kapangidwe kofanana, kuchotsa matumba okhuthala omwe amachititsa kusungunuka kosagwirizana. Mosiyana ndi tinthu tozungulira tomwe timakonda kusonkhana, mawonekedwe a kaolin athyathyathya amalimbikitsa kufalikira kofanana, ngakhale munjira zosakanikirana mwachangu zomwe zimagwiritsidwa ntchito popanga ceramic yayikulu. Pa kutentha kwambiri—gawo lofunika kwambiri pomwe glaze imasintha kuchokera ku utoto wouma, wonga ufa kupita ku wosanjikiza wosalala, wonga galasi—tinthu tofanana ndi mbale za kaolin timadzigwirizanitsa tokha mofanana ndi pamwamba pa ceramic, ndikupanga matrix yofanana, yokhuthala. Kugwirizana kumeneku kumalimbikitsa kusungunuka kofanana poonetsetsa kuti kutentha kumagawidwa mofanana pa glaze, kupewa malo otentha omwe amachititsa kusungunuka kwambiri kapena malo ozizira omwe amasiya tinthu tosakhudzidwa. Kaolin imagwiranso ntchito ngati "kusintha kayendedwe ka madzi," kuwongolera kukhuthala kwa glaze yosungunuka kuti iwonetsetse kuti ifalikira mofanana: kukhuthala kwakukulu kumabweretsa kufalikira kosagwirizana, pomwe kutsika kwambiri kumayambitsa kusonkhana pansi pa malo oyima monga miphika kapena mbali za bafa. Kulinganiza kwapadera kwa Kaolin kwa kulimba ndi pulasitiki kumawongolera kuyenda, kusunga glaze yokhazikika mu makulidwe kudutsa malo athyathyathya (monga mbale) ndi mawonekedwe opindika (monga mbale). Mosiyana ndi zodzaza zolimba (monga quartz kapena feldspar fragments) zomwe zingapangitse kapangidwe koyipa ngakhale zitasungunuka, tinthu tating'onoting'ono ta kaolin timalumikizana kwathunthu ndi silica ndi fluxes, ndikupanga chigawo chofanana chagalasi chokhala ndi zolakwika zochepa pamwamba. Kuphatikizika kwathunthu kumeneku kumachotsa tinthu tosasinthika zomwe zimayambitsa kufiira, ndikupanga malo osalala omwe amawonetsa kuwala mofanana kuti akhale osalala komanso apamwamba.

Ubwino wina waukulu wa ufa wa kaolin ndi kuthekera kwake kupangidwa kuti apange mitundu yosiyanasiyana ya gloss, zomwe zimapatsa opanga ceramic kusinthasintha kwapadera kuti akwaniritse zosowa zosiyanasiyana zamapangidwe osiyanasiyana pazinthu zosiyanasiyana—kuyambira zapamwamba kwambiri mpaka kugwiritsidwa ntchito tsiku ndi tsiku. Kusintha kumeneku kumachokera ku mphamvu ya kaolin pa kukhuthala kwa glaze ndi kulinganiza tinthu, komwe kumatha kusinthidwa bwino mwa kusintha kuchuluka kwake mu kapangidwe kake. Pa zoumba zapamwamba zokongoletsa (monga miphika yopangidwa ndi manja kapena zidutswa zaluso zochepa) ndi mbale zapamwamba (monga china chokongola chomwe chimagwiritsidwa ntchito m'mahotela apamwamba kapena malo odyera apamwamba), opanga amagwiritsa ntchito kuchuluka kwa kaolin kwambiri—nthawi zambiri 20% mpaka 30% ya kapangidwe ka glaze—kophatikizidwa ndi kuchuluka kwabwino kwa flux. Izi zimapanga gloss yozama, yofanana ndi galasi yomwe imawonjezera tsatanetsatane wovuta: mitundu yapamwamba ya china chokongola, mwachitsanzo, amagwiritsa ntchito kapangidwe kameneka kuti apange mawonekedwe a masamba agolide pamwamba powunikira, kusandutsa mbale za chakudya kukhala zidutswa zodziwika bwino. Miphika yokongoletsera yojambulidwa ndi manja imapindula ndi gloss yayikulu iyi, chifukwa imapangitsa mapangidwe a maluwa kapena malo kukhala ngati amoyo powunikira kuwala kuti iwonetse mikwingwirima ya burashi ndi mitundu. Kumbali inayi, kuchuluka kwa kaolin kochepa (10% mpaka 15%) kumapanga zomaliza zopyapyala zomwe zimapangitsa kuti zikhale bwino pakati pa kunyezimira ndi kusalala. Izi ndi zabwino kwambiri pa mbale za tsiku ndi tsiku (monga mbale za chimanga kapena mbale za chakudya chamadzulo zomwe zimagwiritsidwa ntchito m'nyumba) zomwe zimafuna kukongola kosaneneka popanda kuwoneka bwino kwambiri. Zida zoyera (monga masinki a bafa kapena mbale za chimbudzi) zimagwiritsanso ntchito zomaliza zopyapyala, chifukwa kuwala kochepa kumapangitsa malo osambira kumva ofunda komanso okongola, pomwe akusungabe ubwino wa glaze yosalala. Kusintha kumeneku ndi phindu lopulumutsa ndalama kwa opanga: mtundu umodzi wa kaolin ungagwiritsidwe ntchito m'magulu osiyanasiyana azinthu, kuchepetsa kufunikira kwa zodzaza zapadera ndikuchepetsa kasamalidwe ka zinthu. Zimalolanso kusintha kapangidwe mwachangu - kusintha kuchokera ku kuwala kowala kwambiri kupita ku kuwala kowala pang'ono pamzere wa mbale za tebulo kumafuna kusintha kuchuluka kwa kaolin kokha, popanda kusintha kapangidwe kake konse ka glaze.

Kuphatikiza apo, gawo la kaolin pa gloss limakulitsidwa ndi kugwirizana kwake kwapadera ndi zowonjezera zina za glaze, zomwe zimapangitsa mgwirizano womwe umakonza bwino kumaliza ndikukulitsa mwayi wogwiritsa ntchito. Mukaphatikiza ndi zinthu zowoneka bwino (monga ma flux a borosilicate), kaolin imagwira ntchito yochepetsa kukhuthala kwa glaze yosungunuka bwino kuposa ma flux okha. Kukhuthala kochepa kumeneku kumalola glaze kuyenda bwino pamwamba pa ceramic, kudzaza ma pores ang'onoang'ono kapena zolakwika m'thupi la ceramic zomwe zikanatha kugwira mpweya ndikupanga mawanga osawoneka bwino. Zotsatira zake ndi malo osalala kwambiri, owunikira kwambiri omwe amakwaniritsa miyezo yokhwima ya zoumba zapamwamba. Mukagwiritsidwa ntchito ndi zinthu zopaka utoto (monga iron oxide ya zofiira, cobalt oxide ya buluu kapena titanium dioxide ya zoyera), kaolin imagwira ntchito ziwiri: imawonetsetsa kuti gloss siyiwononga umphumphu wa mtundu poletsa tinthu ta utoto kuti tisamange, ndipo imawonjezera kunyezimira kwa mtundu popanga maziko osalala, owunikira omwe amadutsa kuwala kudzera muzoumba zamitundu yosiyanasiyana. Mwachitsanzo, zoumba za buluu za cobalt zokhala ndi kaolin zimawoneka zakuya komanso zodzaza chifukwa kuwala kumawunikira pamwamba posalala, kudutsa muzoumba kawiri (kamodzi polowa, kamodzi powunikira) kuti kuwonjezere mtundu. Magalasi oyera okhala ndi titanium dioxide okhala ndi kaolin amakhala oyera bwino komanso ofanana pochotsa mawanga ofiira omwe amayambitsidwa ndi kufalikira kwa mitundu yosagwirizana. Kugwirizana kumeneku ndikofunikira kwambiri kwa opanga zinthu zadothi zomwe amapanga zinthu zamitundu, chifukwa zimawathandiza kupereka mitundu yowala komanso kuwala kwapamwamba - zinthu ziwiri zomwe ogula amaika patsogolo. Kuphatikiza apo, kugwirizana kwa kaolin ndi zokhazikika (monga zirconium silicate) kumalepheretsa kupangika kwa glaze panthawi yozizira, zomwe zingapangitse mawanga osawoneka bwino komanso oundana omwe amawononga kuwala. Izi zimapangitsa kuti glaze ikhalebe yowala bwino nthawi yayitali itatha kuyaka, zomwe zimapangitsa kuti kaolin ikhale yofunika kwambiri popanga ma glossy omaliza omwe amakwaniritsa miyezo yokhwima yamakampani pazokongola komanso kulimba kwa nthawi yayitali.

Magalasi a tebulo opangidwa ndi ufa wa kaolin amapereka mawonekedwe owala omwe amagwira ntchito yokongola komanso yogwira ntchito, zomwe zimapangitsa kuti akhale ofunikira kwambiri m'nyumba ndi m'mabizinesi. Pamwamba pake, posalala, komanso powala amasintha mbale wamba kukhala zidutswa zomwe zimapangitsa kuti chakudya chiwoneke bwino—chinthu chofunikira kwambiri kwa malo odyera, ophika chakudya ndi odyera kunyumba. Mbale za chakudya chamadzulo zokhala ndi magalasi a kaolin zimapangitsa kuti nyama yokazinga iwoneke yokoma kwambiri powunikira kuwala kuti iwonetse kukongola kwa caramel, pomwe mbale zokhala ndi mawonekedwe owala zimapangitsa kuti saladi ndi zipatso ziwoneke zatsopano powonjezera mitundu yowala. Mwantchito, kuwala kwa kaolin kumapanga malo opanda mabowo omwe amaletsa kupakidwa utoto wa chakudya ndikupangitsa kuyeretsa kukhala kosavuta—kofunikira pakugwiritsa ntchito tsiku ndi tsiku. Msuzi wa phwetekere, curry kapena vinyo wofiira (zodzoladzola zodziwika bwino) sizingalowe mu glaze yosalala, ndikupukuta mosavuta ndi sopo wofatsa ndi madzi. Kulimba kumeneku kumayamikiridwa makamaka m'malo ogulitsira monga malo odyera, komwe mbale zimatsukidwa mobwerezabwereza m'makina otsukira mbale; magalasi opangidwa ndi kaolin amasungabe kuwala kwawo komanso kukana banga ngakhale atasamba kwa mazana ambiri. Zovala zapamwamba monga china chokongola zimadalira kuwala kwa kaolin kuti ziwonjezere zinthu zokongoletsera: zokongoletsera za masamba agolide, maluwa ojambulidwa ndi manja kapena zojambula zovuta zosinthira zimaonekera bwino kwambiri motsutsana ndi mawonekedwe owala, zomwe zimapangitsa chidutswa chilichonse kukhala chosonkhanitsidwa. Ngakhale zovala za tsiku ndi tsiku zomwe zimakhala zotsika mtengo zimapindula ndi kuwala kwa kaolin, chifukwa zimakweza khalidwe lomwe anthu amaliona kuti ndi labwino—ogula nthawi zambiri amaphatikiza kunyezimira ndi kulimba, zomwe zimapangitsa kuti zidutswazi zikhale zokongola kwambiri kuposa njira zina zosawoneka bwino. Mwachitsanzo, makapu a ceramic otsika mtengo okhala ndi magalasi a kaolin amamveka bwino kwambiri m'manja, okhala ndi malo osalala omwe amakana kukanda kuchokera ku ziwiya ndipo amasunga kuwala kwake kwa zaka zambiri.

Zipangizo zaukhondo—kuphatikizapo masinki, zimbudzi, mabafa ndi malo osambira—zimadalira kwambiri ma glaze opangidwa ndi kaolin kuti akwaniritse kunyezimira komanso ukhondo womwe umakwaniritsa miyezo yokhwima yogwiritsira ntchito m'nyumba ndi m'malonda. Ukhondo ndi wofunika kwambiri pa ntchito izi, ndipo kaolin yonyezimira imapanga malo osaboola, osalala omwe amalimbana ndi dothi, litsiro ndi mabakiteriya. Mosiyana ndi malo oboola kapena osalimba omwe amamanga mabakiteriya (omwe amachititsa kuti nkhungu ndi bowa zimere), kaolin yonyezimira imalola madzi kuuluka ndikutuluka, ndikunyamula dothi. Izi zimapangitsa kuyeretsa kukhala kofulumira komanso kogwira mtima: masinki a m'bafa okhala ndi kaolin glaze amatha kupukutidwa ndi nsalu yonyowa, kuchotsa kufunikira kotsuka mwamphamvu kapena mankhwala oyeretsera. Mabafa okhala ndi kaolin glaze opangidwa ndi kaolin amalimbana ndi kusungunuka kwa sopo, vuto lofala m'bafa, chifukwa malo osalala amaletsa zotsalira za sopo kuti zisamamatire. Pa malo amalonda monga mahotela kapena zimbudzi za anthu onse—komwe magalimoto ambiri ndi kuyeretsa pafupipafupi ndizomwe zimafunika—kulimba kwa kaolin glaze ndikofunikira kwambiri: imasunga mawonekedwe owala komanso aukhondo ngakhale atakumana ndi mankhwala oyeretsera tsiku lililonse komanso atagwiritsidwa ntchito kwambiri. Opanga zinthu zaukhondo amaonanso kuti kaolin imapatsa mawonekedwe ofanana pamalo akuluakulu komanso ovuta: mkati mwa bafa, okhala ndi mawonekedwe opindika komanso kukula kwakukulu, amafunika glaze yomwe imayenda mofanana kuti apewe mawanga osawoneka bwino omwe amakopa dothi. Kapangidwe ka Kaolin kosintha kayendedwe ka madzi kamatsimikizira kunyezimira kosalekeza kuchokera pamwamba mpaka pansi pa bafa, kusunga mgwirizano wowoneka bwino. Kuphatikiza apo, glaze yonyezimira yochokera ku kaolin imawonjezera kusinthasintha kwa utoto mu zinthu zoyera zaukhondo—muyezo wamakampani wowonera ukhondo. Kaolin imaletsa chikasu kapena kufinya kwa glaze yoyera pakapita nthawi, kusunga masinki ndi zimbudzi zikuwoneka zowala komanso zatsopano kwa zaka zambiri, ngakhale m'malo ovuta kumene mchere umatha kusokoneza utoto wa glaze.

Zokongoletsera zadothi—zophatikizapo miphika, matailosi a pakhoma, ziboliboli, zikwangwani zaluso ndi zokongoletsa zomangamanga—zimagwiritsa ntchito ufa wa kaolin mu zokongoletsa kuti zikwaniritse kunyezimira kokongola komanso kogwirizana komwe kumakweza kukongola kwa zaluso komanso mtengo wamsika. Ojambula ndi opanga zokongoletsa amadalira luso la kaolin lopanga malo osalala, owala omwe amawonjezera njira zosiyanasiyana zokongoletsera, kuyambira kujambula ndi manja ndi mapangidwe okongoletsa mpaka zolemba ndi kupukuta mpweya. Miphika yojambulidwa ndi manja ndi chitsanzo chabwino: zokongoletsa zopangidwa ndi kaolin zimapereka nsalu yosalala yomwe imalola ojambula kugwiritsa ntchito zigawo zoonda komanso zolondola za utoto, ndipo kunyezimira kumawonjezera kunyezimira kwamitundu. Mapangidwe a maluwa okhala ndi ma pastel ofewa amawoneka ofewa kwambiri, pomwe mapangidwe olimba mtima owoneka bwino amakula pamene kuwala kumawonekera pamwamba ponyezimira, kuwonetsa kusiyana pakati pa mitundu. Mapangidwe okongoletsa—mapangidwe opangidwa ndi ziboliboli omwe amatuluka pamwamba pa zokongoletsa—amapindula ndi kunyezimira kwa kaolin kuti awonjezere kapangidwe: zojambula zamaluwa zokwezedwa pa miphika zimayika mithunzi yocheperako kumbuyo kowala, zomwe zimapangitsa kuti tsatanetsatane uwoneke bwino komanso wamitundu itatu. Matailosi a pakhoma omwe amagwiritsidwa ntchito ngati zokongoletsera m'makhitchini, m'zipinda zosambira kapena m'zipinda zochezera amadalira kunyezimira kwa kaolin kuti apange mawonekedwe ofanana. Malo akuluakulu oyikamo (monga ma backplashes a kukhitchini kapena makoma okhala ndi bafa) amafuna matailosi okhala ndi miyeso yofanana yowala kuti apewe malo osagwirizana omwe amasokoneza kapangidwe kake; kaolin imawonetsetsa kuti matailosi onse amakhala ndi kuwala kofanana, ngakhale m'magulu osiyanasiyana opanga. Kufanana kumeneku ndikofunikira kwambiri kwa mitundu yapamwamba ya matailosi omwe amasamalira mapulojekiti apamwamba opangira mkati. Zifaniziro zazing'ono—kaya zilembo zosonkhanitsidwa, ziboliboli za nyama kapena zinthu zachipembedzo—zimagwiritsa ntchito kuwala kwa kaolin kuti ziwonjezere tsatanetsatane wofanana ndi wamoyo: mawonekedwe ankhope monga maso ndi kumwetulira amawoneka owoneka bwino, pomwe zovala kapena mawonekedwe a ubweya zimakula kwambiri. Ma studio a ceramic aluso nthawi zambiri amagwiritsa ntchito magalasi apamwamba a kaolin pazinthu zapadera, chifukwa kuwala kumasintha mawonekedwe osavuta a dongo kukhala zaluso zokongola zomwe zimadula mitengo yapamwamba. Ngakhale zinthu zokongoletsera zopangidwa mochuluka monga zoyika makandulo za ceramic kapena miphika ya zomera zimapindula ndi kuwala kwa kaolin, chifukwa kumakweza mawonekedwe awo kuchokera ku wamba kupita ku okongola, kuwapangitsa kukhala okongola kwambiri kwa ogula omwe akufuna kukongoletsa nyumba.
