Doorka kaarboon-qaadista ee crontium-ka ah glaze Markii horay loo sii daayay ee 'fle'x', gaaska badankood waa laga saari karaa shaashadda cluze ceyriinka, sidaa darteed yareynta jiilka xumbada iyo godadka yaryar ee dusha sare ee glaze colaze. Tani waxay si gaar ah muhiim ugu tahay badeecooyinka dhoobada leh heerkulka sare ee rasaasta iyo wareegga gaagaaban, sida dhoobada maalinlaha ah iyo dhoobada fayadhowr.
Tilmaamaha ayaa hadda si balaadhan loogu isticmaalaa jajabinta dheri-dheriga ee si dhakhso leh loo eryay. Sababta oo ah heerkulka dhalaalaya ee ugu hooseeya iyo heerkulka weyn ee heerkulka, Frit waxay leedahay door aan la beddeli karin oo ku saabsan diyaarinta alaabada dhoobada si dhakhso ah loo eryay. Loogu talagalay boorsada heerkulka rasaasta oo sareysa, sheyga ceyriinka ayaa had iyo jeer loo isticmaalaa sida glaze ugu weyn. Xitaa haddii Frit loo adeegsado glaze, xaddiga Frit-ka aad ayuu u yar yahay (cadadka Frit ee Glaze uu ka yar yahay 30%.).
Glit-ka-bilaashka ah ee jilicsan ee rasaasta leh ayaa iska leh qeybta farsamada ee glaze frit ee dhoobada. Waxaa laga sameeyaa alaabta ceyriinka ee soosocda culeyska: 15-30% Quartz, 30-50% Feldspar, oo ah Feldspar, 7-15% ee Borax, oo ah 5-5% ee Barax acid, 3-6% ee Baras acid, oo ah 3-6% ee kaadida, 6-6% ee Stalactite. 12%, zinc okside 3-6%, xargaha xargaha stronium 2-5%, lithium carbonate 2-4%, slorat hydroxide 2-8%. Gaaritaanka eber dhalaalaya ee sunta rasaasta waxay si buuxda u dabooli kartaa baahiyaha dadka ee noocyo caafimaad leh oo tayo sare leh.
