Iwe unofanirwa kunge wakaona maceramics emhando dzakasiyana-siyana uye mavara.Zvisinei, unoziva here kuti nei maceramics anogona kupa marudzi ese emavara akanaka?
Muchokwadi, makeramiki anowanzo kuve neinopenya uye yakatsetseka "glaze" pamusoro pavo.
Glaze inogadzirwa nemamineral raw materials (senge feldspar, quartz, kaolin) uye makemikari mbishi zvinhu zvakasanganiswa mune imwe chiyero uye yakatsetseka yakatsetseka kuita slurry fluid, inoiswa pamusoro pemuviri weceramic.Mushure meimwe tembiricha yecalcining uye kunyunguduka, kana tembiricha inodonha, ichiita girazi rakatetepa rakatsetseka pamusoro peceramic.
Kare makore anopfuura 3000 apfuura, vanhu vekuChina vaive vatodzidza kushandisa matombo nemadhaka kugadzira magirazi ekushongedza maceramics.Gare gare, maartist eceramic akashandisa chiitiko chekupisa madota achingowira pamuviri weceramic kugadzira kupenya, ndokuzoshandisa madota echirimwa sechinhu chakabikwa chekugadzira glaze.
Iyo glaze inoshandiswa mukugadzirwa kwemazuva ano ekeramics yemazuva ano yakakamurwa kuita lime glaze uye feldspar glaze.Lime glaze inogadzirwa kubva kune glaze ibwe (a natural mineral raw material) uye lime-flyash (chikamu chikuru icalcium oxide), nepo feldspar glaze iri. kunyanya inoumbwa nequartz, feldspar, marble, kaolin, nezvimwe.
Kuwedzera simbi oxides kana kupinza mamwe makemikari emu lime glaze uye feldspar glaze, uye zvichienderana nekupisa kwekupisa, mavara akasiyana-siyana anogona kuumbwa.Kune cyan, dema, girini, yero, tsvuku, bhuruu, pepuru, etc. White porcelain inoratidzika isina ruvara inopenya glaze. inonamira zvakasimba kumuviri weporcelain, iyo inoita kuti porcelain iite gobvu, inopenya, uye yakapfava, isingapindiki nemvura kana kuburitsa mabhururu, ichipa vanhu kunzwa kwakajeka segirazi.Panguva imwecheteyo, inogona kuvandudza kusimba, kudzivirira kusvibiswa, uye kufambisa kuchenesa.
