Mtundu umatha kusiyanitsa chidebe chagalasi, kuteteza zomwe zili mkati ndi cheza chosafunikira cha ultraviolet kapena kupanga mitundu ingapo pagulu lazinthu.
Amber Glass
Amber ndiye galasi lodziwika bwino kwambiri, ndipo amapangidwa powonjezera pamodzi chitsulo, sulufule, ndi kaboni.
Amber ndi galasi "yochepetsedwa" chifukwa cha mpweya wambiri womwe umagwiritsidwa ntchito. Zipangizo zonse zamagalasi okhala ndi kaboni, koma ambiri ndi magalasi "okosijeni".
Galasi ya Amber imatenga pafupifupi ma radiation onse okhala ndi mawonekedwe ofikira ofupika kuposa 450 nm, omwe amateteza kwambiri ku radiation ya ultraviolet (yofunikira kwambiri pazinthu monga mowa ndi mankhwala ena).
Galasi Yobiriwira
Green Glass imapangidwa powonjezera Chrome oxide (Cr + 3) yopanda poizoni; kukwera kwake kumakhala kothimbirira, kwakuda kwambiri.
Galasi lobiriwira limatha kuphatikizidwa, monga Emerald Green kapena Georgia wobiriwira, kapena kuchepetsedwa, monga ndi Dead Leaf green.
Galasi lobiriwira lochepetsedwa limapereka chitetezo chochepa cha ultraviolet.
Galasi ya Blue Glass
Buluu imapangidwa powonjezera cobalt oxide, yowoneka bwino kwambiri kotero kuti magawo ochepa okha miliyoni amafunikira kuti apange utoto wonyezimira monga mthunzi womwe umagwiritsidwa ntchito pamadzi ena am'mabotolo.
Magalasi amtundu wabuluu nthawi zambiri amakhala magalasi okhala ndi oxidized. Komabe, galasi loyera labuluu limatha kupangidwa pogwiritsa ntchito chitsulo chokha ndi kaboni ndikusiya sulfure, ndikupangitsa kuti likhale labuluu locheperako.
Kupanga mtundu wabuluu wocheperako samachitika kawirikawiri chifukwa cha kuchuluka kwa zovuta kutsitsa galasi ndikuwongolera utoto.
Magalasi amitundu yambiri amasungunuka m'matangi agalasi, njira yofanana ndi magalasi amwala. Powonjezerapo zokongoletsera kumtunda, njerwa yomwe ili ndi njerwa yomwe imapereka galasi pamakina opangira ng'anjo yamwala wamwala, imapanga mitundu yokhala ndi oxidized.
