1. Kapu ya galasi ya sodium ndi mchere ndiyonso kapu yamadzi yagalasi yofala kwambiri m'miyoyo yathu.Zofunikira zake ndi silicon dioxide ndi sodium oxide ndi calcium oxide.Kapu yamadzi yotereyi imapangidwa ndi makina komanso kuwomba pamanja, komwe kumakhala mtengo wotsika komanso zinthu wamba m'moyo.Ngati sodium ndi lipid glassware imagwiritsidwa ntchito ngati chakumwa chotentha, nthawi zambiri imafunika kutenthedwa pochoka ku fakitale, apo ayi chikhocho chidzasweka pamene kusiyana kwa kutentha kuli kwakukulu kwambiri.
2. Kapu yagalasi yapamwamba kwambiri, galasi ili limatchedwa kuti boron oxide.Ma seti a tiyi ndi tiyi omwe amagwiritsidwa ntchito ndi tiyi amatha kupirira kusintha kwa kutentha kwakukulu popanda kusweka.Koma galasi ili likuwoneka lopyapyala, lopepuka, komanso losauka.
3. Chikho cha galasi la kristalo.Galasi yamtunduwu ndi chinthu chapamwamba kwambiri mugalasi.Chifukwa pali zinthu zambiri zachitsulo zomwe zili, kupindika kwake ndi kuwonekera kwake kuli pafupi kwambiri ndi makristasi achilengedwe, omwe amatchedwa galasi la crystal.Pali mitundu iwiri ya galasi la crystal, galasi lotsogolera ndi galasi lopanda lead.Magalasi opangidwa ndi lead saloledwa kudya, makamaka pakumwa zakumwa za acidic zomwe zimagwiritsidwa ntchito kwambiri.Zinthu zotsogolera zidzasungunuka kukhala zamadzimadzi acidic.Kugwiritsa ntchito nthawi yayitali kumatha kuyambitsa chiphe.Krustalo wopanda lead si chinthu chotsogola komanso chosavulaza thupi.
