Microcrystalline abrasion-yihanganira umupira wa alumina nuburyo bwiza bwo gusya, bikozwe mubikoresho byatoranijwe byateye imbere, ikoranabuhanga rigezweho, kandi bibarwa mu itanura ryubushyuhe bwo hejuru.Iki gicuruzwa gifite ubucucike bwinshi, ubukana bwinshi, kwambara gake, guhagarara neza kwimitingito no kurwanya ruswa.Nuburyo bwiza cyane bwo gusya glazes, bilet hamwe nifu ya minerval, kandi bikoreshwa nkigikoresho cyo gusya kumashanyarazi yumupira wa ceramic na sima., Ipitingi, inganda, ifu yumutungo kamere nizindi nganda.
