1.Oridinary iav (Na2SiO3, CaSiO3, SiOor Na2O · CaO · 6SiO2)
2. Quartz iav (iav) Lub iav ua nrog ntshiab quartz ua cov ntsiab raw raw tsuas muaj SiO2.
3. Tempered iav (Na2SiO3, CaSiO3, SiOor Na2O · CaO · 6SiO2)
4. Tinted iav (Ib co kab hlau oxide muaj ntxiv rau cov iav txheej txheem iav. CU2o-red; CUO-turquoise; Cdos-daj, daj; CO2O3-blue; Ni2O3-maub ntsuab; MnO2, ntshav; Colloidal Au-red; -dal Ag-daj)
5. Tivthaiv iav (cov ntaub ntawv pov thawj cov khoom ntim rau hauv lub iav kom ua tau zoo rau kev tiv thaiv kev tiv thaiv ntawm tus kheej los ntawm kev tiv thaiv lub teeb ci, muaj zog kub lossis hluav taws xob sib kis.Thiab li grey-dichromate, hlau oxide absorption ntawm ultraviolet lub teeb thiab ib feem ntawm qhov pom kev pom xim xiav-ntsuab-nickel oxide thiab ferrous oxide nqus tau dej khov thiab ib feem ntawm pom lub teeb; hlau iav ua rau oxide absorbs-rays thiab xoos xiav xiav-bichromate ferrous oxide, iron oxide absorb ultraviol -et, infrared thiab feem ntau pom teeb; ntxiv cadmium oxide thiab yug oxide mus nqus dej neutron.
6. Cov Khaub Ncauj Taub Ntshav (Glass Ceramics): Uas yog hu ua crystal glass or ceramics, yog nyob hauv iav qhov dog dig los ntawm kev ntxiv kub, nyiaj, copper thiab lwm yam siv lead ua, tsis muaj cov pas hlau thiab gems, raws li radar-shield thiab lub taub hau loj.
