Doorka strontium carbonate ee glaze: frit waa in horay loo dhalaaliyo alaabta ceeriin ama noqoto jidh quraarad, kaas oo ah walxo cayriin ah oo caadi ahaan loo isticmaalo dhaldhalaalka dhoobada.Marka hore loo dhalaaliyo qulqulka, gaaska intiisa badan waa laga saari karaa alaabta ceeriin ee dhalaalka ah, sidaas darteed hoos u dhigida jiilka xumbo iyo godadka yaryar ee dusha sare ee dhalaalka dhoobada ah.Tani waxay si gaar ah muhiim ugu tahay alaabta dhoobada leh ee leh heerkulka sare ee dabka iyo wareegga gaabnaanta, sida dhoobada maalinlaha ah iyo dhoobada nadaafadda.
Frits ayaa hadda si weyn loogu isticmaalaa dhaldhalaalka dheriga ee degdega ah.Sababtoo ah heerkulkiisa hore ee dhalaalka hoose iyo kala duwanaanta heerkulka sare ee dabka, frit ayaa door aan la bedeli karin ku leh diyaarinta alaabta dhoobada ee si degdega ah loo shiday.Wixii weel leh heerkulka sare ee dabka, alaabta ceeriin ayaa had iyo jeer loo isticmaalaa sida dhalaalka ugu weyn.Xataa haddii frit loo isticmaalo dhaldhalaalka, xadiga shiilku aad buu u yar yahay (qadarka barafka ee glaze ka yar 30%).
glaze-free frit-free ah ayaa iska leh goobta farsamada ee dhaldhalaalka frit ee dhoobada.Waxay ka samaysan tahay alaabta ceeriin ee soo socota: 15-30% quartz, 30-50% of feldspar, 7-15% of borax, 5-15% of boric acid, 3-6% of barium carbonate, 6- 6% ee stalactite.12%, zinc oxide 3-6%, strontium carbonate 2-5%, lithium carbonate 2-4%, talc 2-4%, aluminium hydroxide 2-8%.Gaaritaanka eber dhalaalidda rasaasta waxay si buuxda u dabooli kartaa baahida dadka ee alaabooyinka caafimaadka leh iyo kuwa tayada sare leh.
