Nigute ibara ryubutaka bwa ceramic ryakozwe?

Ugomba kuba warabonye ububumbyi bwuburyo butandukanye namabara.Nyamara, uzi impamvu ububumbyi bushobora kwerekana ubwoko bwose bwamabara meza?

Mubyukuri, ububumbyi muri rusange bufite "glaze" yuzuye kandi yoroshye.

Glaze ikozwe mu bikoresho fatizo (nka feldspar, quartz, kaolin) hamwe n’ibikoresho fatizo bya chimique bivanze ku kigereranyo runaka hamwe nubutaka bwiza mumazi meza, bigashyirwa hejuru yumubiri wubutaka.Nyuma yubushyuhe runaka bwo kubara no gushonga, iyo ubushyuhe bugabanutse, bikora ikirahure cyoroshye cyane hejuru yubutaka bwa ceramic.

Nko mu myaka irenga 3000 iheze, Abashinwa bari bamaze kwiga gukoresha amabuye n'ibyondo kugirango bakore glazes mu gushushanya ububumbyi.Nyuma, abahanzi bo mubutaka bakoresheje ibintu by ivu ryamavuta bisanzwe bigwa kumubiri wubutaka kugirango babe glaze, hanyuma bakoresha ivu ryibimera nkibikoresho fatizo byo gukora glaze.

Ikirahuri gikoreshwa mu gukora ubukorikori bugezweho bwa buri munsi bugabanijwemo lime glaze na glaze ya feldspar.Icyuma cya lime gikozwe mu ibuye rya glaze (ibikoresho bisanzwe bya minerval naturel) na lime-flyash (igice nyamukuru ni calcium oxyde), naho glaze ya feldspar ni ahanini igizwe na quartz, feldspar, marble, kaolin, nibindi

Ongeramo okiside yicyuma cyangwa kwinjira mubindi bikoresho bya shimi mumashanyarazi ya lime na feldspar glaze, kandi ukurikije ubushyuhe bwumuriro, hashobora kubaho amabara atandukanye ya glaze.Hano hari cyan, umukara, icyatsi, umuhondo, umutuku, ubururu, ibara ry'umuyugubwe, n'ibindi .Ibara rya farashi yera ni glaze isa neza idafite ibara.Muri rusange, umubyimba wumubiri wumubumbyi wa ceramic ni santimetero 0.1, ariko nyuma yo kubarwa mu itanura, bizagenda yizirika cyane kumubiri wa farashi, ituma farashi yuzuye, irabagirana, kandi yoroshye, ntishobora kwinjira mumazi cyangwa kubyara ibibyimba, biha abantu ibyiyumvo byiza nkindorerwamo.Muri icyo gihe, irashobora guteza imbere kuramba, gukumira umwanda, no koroshya isuku.
