Uruhare rwa karubone ya strontium muri glaze: frit nugushonga mbere yo gushonga ibikoresho bibisi cyangwa guhinduka umubiri wikirahure, nikintu gikunze gukoreshwa flux mbisi ya ceramic glaze.Iyo byashongeshejwe mbere yo gutemba, gaze hafi ya yose irashobora gukurwa mubikoresho fatizo bya glaze, bityo bikagabanya kubyara ibibyimba nu mwobo muto hejuru yubutaka bwa ceramic.Ibi ni ingenzi cyane cyane kubicuruzwa byubutaka hamwe nubushyuhe bwo hejuru bwo kurasa hamwe nigihe gito cyo kurasa, nkibumba bya buri munsi nubutaka bwisuku.
Kuri ubu imbuto zikoreshwa cyane mumashanyarazi yihuta cyane.Kubera ubushyuhe buke bwambere bwo gushonga hamwe nubushyuhe bunini bwo kurasa, frit ifite uruhare rudasubirwaho mugutegura ibicuruzwa byubatswe byubatswe byihuse.Kuri faroseri hamwe nubushyuhe bwo hejuru bwo kurasa, ibikoresho bibisi buri gihe bikoreshwa nkurumuri nyamukuru.Nubwo ifiriti ikoreshwa kuri glaze, ingano ya frit ni nto cyane (ingano ya frit muri glaze ntabwo iri munsi ya 30%.).
Isoko idafite frit glaze ni iyumwanya wa tekinike ya frit glaze kubutaka.Ikozwe mubikoresho fatizo bikurikira muburemere: 15-30% ya quartz, 30-50% ya feldspar, 7-15% ya borax, 5-15% ya acide boric, 3-6% ya karubone ya barium, 6- 6% ya stalactite.12%, okiside ya zinc 3-6%, karubone ya strontium 2-5%, karubone ya lithium 2-4%, talc yagabanijwe 2-4%, hydroxide ya aluminium 2-8%.Kugera kuri zeru gushonga bya sisitemu birashobora guhaza byimazeyo ibyo abantu bakeneye mubuzima bwiza kandi bwiza.
