Kapangidwe ka magalasi wamba ndi Na2SiO3, CaSiO3, SiO2 kapena Na2O·CaO·6SiO2, ndi zina zotero.
Chigawo chachikulu ndi silicate mchere wawiri, womwe ndi wolimba wa amorphous wokhala ndi dongosolo lachisawawa.Amagwiritsidwa ntchito kwambiri m'nyumba kuti atseke mphepo ndi kuwala, ndipo ndi osakaniza.
Palinso magalasi achikuda osakanizidwa ndi oxides kapena mchere wazitsulo zina kusonyeza mtundu, ndi magalasi otenthedwa omwe amapezedwa ndi njira zakuthupi kapena zamankhwala.
Mabotolo agalasi ndi zitini ayenera kukhala ndi ntchito zina ndi kukwaniritsa mfundo zina.
①Ubwino wagalasi: yoyera komanso yofanana, yopanda chilema monga mchenga, mikwingwirima, ndi thovu.Galasi yopanda mtundu imakhala yowonekera kwambiri;mtundu wa galasi wachikuda ndi yunifolomu ndi khola, ndipo akhoza kuyamwa kuwala mphamvu ya wavelength inayake.
②Zakuthupi ndi mankhwala: Zili ndi mlingo wina wa kukhazikika kwa mankhwala ndipo sizigwirizana ndi zomwe zili mkati.Ili ndi kukana kwina kwa mantha ndi mphamvu zamakina, ndipo imatha kupirira kutentha ndi kuzizira monga kutsuka ndi kutseketsa, komanso kupirira kudzazidwa, kusungirako ndi zoyendetsa, ndipo ikhoza kukhala yosawonongeka pamene ikukumana ndi kupsinjika kwa mkati ndi kunja, kugwedezeka, ndi zotsatira.
③Kupanga mawonekedwe: sungani voliyumu, kulemera kwake ndi mawonekedwe ake, makulidwe a khoma lofanana, pakamwa mosalala komanso pompopompo kuti muwonetsetse kudzazidwa kosavuta komanso kusindikiza bwino.Palibe zoperewera monga kupotoza, kusalinganika pamwamba, kusagwirizana ndi ming'alu.
