Iqhaza le-strontium carbonate ku-glaze: i-frit iwukuncibilikisa ngaphambili impahla eluhlaza noma ukuba umzimba wengilazi, okuwumathiriyeli osetshenziswa kakhulu we-flux we-ceramic glaze.Uma inyibilika ngaphambili ibe yi-flux, igesi eningi ingasuswa ku-glaze impahla eluhlaza, ngaleyo ndlela kuncishiswe ukukhiqizwa kwamabhamuza nezimbobo ezincane endaweni ecwebezelayo ye-ceramic.Lokhu kubaluleke kakhulu emikhiqizweni ye-ceramic enezinga lokushisa eliphezulu lokudubula kanye nomjikelezo omfushane wokudubula, njengama-ceramics nsuku zonke kanye nezitsha ze-sanitary ceramics.
Ama-Frits njengamanje asetshenziswa kabanzi ekucwebezelweni kobumba okwenziwa ngokushesha.Ngenxa yezinga lokushisa eliphansi elincibilikayo lokuqala kanye nebanga elikhulu lokushisa lokudubula, i-frit inendima engenakushintshwa ekulungiseleleni imikhiqizo ye-ceramic yezakhiwo eshiswa ngokushesha.Ku-porcelain enezinga lokushisa eliphakeme lokudubula, izinto ezingavuthiwe zihlala zisetshenziswa njenge-glaze eyinhloko.Ngisho noma i-frit isetshenziselwa i-glaze, inani le-frit lincane kakhulu (inani le-frit ku-glaze lingaphansi kwama-30%).
I-frit glaze engenamthofu ingeyomkhakha wezobuchwepheshe we-frit glaze yezitsha zobumba.Yenziwe ngezinto ezisetshenziswayo ezilandelayo ngesisindo: 15-30% yequartz, 30-50% yefeldspar, 7-15% yeborax, 5-15% ye-boric acid, 3-6% ye-barium carbonate, 6- I-6% ye-stalactite.12%, zinc oxide 3-6%, strontium carbonate 2-5%, lithium carbonate 2-4%, slaked talc 2-4%, aluminium hydroxide 2-8%.Ukuthola iqanda lokuncibilika komthofu kungahlangabezana ngokugcwele nezidingo zabantu zezitsha zobumba ezinempilo nezisezingeni eliphezulu.
