Basa re strontium carbonate mu glaze: frit ndeyekunyungudutsa zvinhu zvisina kucheneswa kana kuti kuva girazi, inova chinhu chinoshandiswa zvakanyanya pa glaze ye ceramic. Kana yanyungudutswa kuita flux, gasi rakawanda rinogona kubviswa kubva mu glaze, nokudaro zvichideredza kugadzirwa kwemabubbles nemaburi madiki pamusoro pe glaze ye ceramic. Izvi zvakakosha zvikuru kune zvigadzirwa zve ceramic zvine tembiricha yakakwira uye kupfupika kwekupisa, zvakaita se ceramics dzezuva nezuva uye sanitary ceramics.
Mafriti parizvino anoshandiswa zvakanyanya mumagirazi ehari anokurumidza kupiswa. Nekuda kwekupisa kwayo kushoma kwekutanga uye tembiricha yakakura yekupiswa, friti ine basa guru mukugadzirira zvigadzirwa zveceramic zvekuvaka zvinopiswa nekukurumidza. Kune porcelain ine tembiricha yepamusoro yekupiswa, zvinhu zvakagadziriswa zvinogara zvichishandiswa segirazi guru. Kunyangwe kana friti ichishandiswa pagirazi, huwandu hwefriti hushoma kwazvo (huwandu hwefriti mugirazi husingasviki 30%).
Glaze isina mutobvu ndeyemumunda wehunyanzvi hwe frit glaze ye ceramics. Yakagadzirwa nezvinhu zvinotevera nehuremu: 15-30% ye quartz, 30-50% ye feldspar, 7-15% ye borax, 5-15% ye boric acid, 3-6% ye barium carbonate, 6-6% ye stalactite. 12%, zinc oxide 3-6%, strontium carbonate 2-5%, lithium carbonate 2-4%, slaked talc 2-4%, aluminium hydroxide 2-8%. Kuwana zero melting ye lead kunogona kugutsa zvizere zvinodiwa nevanhu zve ceramics dzine hutano uye dzemhando yepamusoro.
