Zvinhu zvikuru zvegirazi rine ruvara zvakacheneswa quartz jecha uye potassium feldspar, albite, lead oxide (iyo yakakosha chikamu chegirazi), saltpeter (potassium nitrate: KNO3; kutonhora), alkali simbi, alkaline pasi simbi (magnesium chloride: MgCl, melting aid. , kuwedzera kusimba), aluminium oxide (kuwedzera kupenya uye kusimba kwemakemikari) Chromogenic agents emarudzi akasiyana-siyana (akadai seyero yegirini yesimbi oxide, yebhuruu girini yemhangura oxide, nezvimwewo) uye kujekesa midziyo (white arsenic, antimony trioxide, nitrate, sulfate , fluoride, chloride, cerium oxide, ammonium munyu, nezvimwewo).Girazi rekristaro rakanyungudutswa pakupisa kwepamusoro kwe1450 ° C, uye magirazi emifananidzo anogadzirwa pakudziya kwakadzika kwe850 ° C ~ 900 ° C kuburikidza nemaitiro akanaka ekudonha uye kusanganisa kwemavara kukanda.MuchiRungu, girazi rine mishonga yemutobvu rinowanzodaidzwa kunzi crystal kana crystal glass nekuda kwekufambiswa kwaro uye kujeka, izvo zvakafanana nemakristasi chaiwo.MuChina, inonzi girazi.Serudzi rwegirazi regirazi reruvara, chikamu chemutobvu chinosanganiswa negirazi chine mavara (chinoita kuti zvigadzirwa zvegirazi zvive nepamusoro refractive index uye kutaridzika uye kupenya. Parizvino, zvizhinji zvezvigadzirwa zvinoshandiswa pakukanda zvine zvinopfuura 24%).Tsanangudzo dzinosiyana nyika nenyika, senge 10% muEuropean Union uye 24% ~ 40% muCzech Republic.Kazhinji kutaura, kana chikamu che lead oxide chasvika kupfuura 24%, girazi rine yakanaka transmittance uye refractive index, uye zvakare inorema uye yakapfava.
Kuvhiringika kwemazita egirazi rine mavara uye zvirevo zvaro zvine hukama munhoroondo zvakakonzera kusanzwisisa uye kusanzwisisa kwegirazi rine mavara."Glazed tile" uye yemazuva ano "Boshan yakagadzirwa girazi rine ruvara" ndiyo inonyanya kuratidzwa mienzaniso.
