1. Kapu yamadzi yagalasi ya soda-laimu ndiyonso kapu yamadzi yodziwika bwino m'miyoyo yathu.Zigawo zake zofunika ndi silicon dioxide, sodium oxide, ndi calcium oxide.Kapu yamadzi yamtunduwu imapangidwa ndi makina ndi kuwomba pamanja, mtengo wotsika, komanso zofunikira zatsiku ndi tsiku.Ngati soda ya soda glassware imagwiritsidwa ntchito pakumwa zakumwa zotentha, nthawi zambiri imafunika kupsya mtima pochoka ku fakitale, apo ayi chikhocho chidzasweka ngati kusiyana kwa kutentha kuli kwakukulu kwambiri.
2. Chikho chachikulu cha galasi lamadzi la borosilicate, galasi lamtunduwu limatchedwa chifukwa cha kuchuluka kwa boron oxide.Tiyi ndi tiyi zomwe zimagwiritsidwa ntchito popanga tiyi zimatha kupirira kutentha kwakukulu popanda kusweka.Koma galasi lamtunduwu limawoneka lochepa thupi, lopepuka komanso loipa.
3. Chikho chamadzi a galasi la galasi, galasi lamtundu uwu ndilopamwamba kwambiri mu galasi, chifukwa lili ndi zinthu zambiri zachitsulo, ndondomeko yake ya refractive ndi kuwonekera zili pafupi kwambiri ndi kristalo wachilengedwe, choncho imatchedwa galasi la kristalo.Pali mitundu iwiri ya galasi la crystal, galasi lotsogolera ndi galasi lopanda lead.Magalasi a krustalo wamtovu samavomerezedwa kuti amwe, makamaka mukamamwa zakumwa za acidic kuchokera m'magalasi akumwa.Mtovu udzasungunuka kukhala madzi acidic, ndipo kumwa kwa nthawi yayitali kumayambitsa chiphe.Magetsi opanda mtovu alibe zinthu za lead ndipo alibe vuto lililonse m'thupi.Pogula galasi, muyenera kuyang'ana galasi lopanda kutsogolera.Ponena za mtundu wa galasi, sikofunikira, koma uyenera kukhala wopanda lead.Pamapeto pake, pansi pa kapu ndi chokhuthala komanso cholimba.
