1. Soda-lime girazi remvura kapu zvakare ndiyo inonyanya kufarirwa kapu yemvura yegirazi muhupenyu hwedu.Zvikamu zvaro zvakakosha silicon dioxide, sodium oxide, uye calcium oxide.Rudzi urwu rwekapu yemvura inogadzirwa nemuchina uye kuvhuvhuta kwemaoko, mutengo wakaderera, uye zvinodiwa zvezuva nezuva.Kana iyo soda lime glassware inoshandiswa kunwa zvinwiwa zvinopisa, inowanzoda kushatirwa kana ichibva mufekitari, kana zvisina kudaro kapu inoputika kana kusiyana kwekushisa kwakanyanya.
2. High borosilicate glass water cup, rudzi urwu rwegirazi runonzi nekuda kwehuwandu hwehuwandu hwe boron oxide.Maseti etii uye teapots anowanzo shandiswa kugadzira tii anogona kutsungirira shanduko huru yekupisa pasina kutyora.Asi rudzi urwu rwegirazi rinotaridzika kutetepa, huremu huremu, uye hunonzwa husina kunaka.
3. Crystal girazi remvura mukombe, rudzi urwu rwegirazi chigadzirwa chepamusoro-soro mugirazi, nokuti ine zvinhu zvakawanda zvesimbi, iyo refractive index uye transparency iri pedyo zvikuru nekristal yakasikwa, saka inonzi crystal glass.Kune marudzi maviri egirazi regirazi, lead crystal glass uye lead-free crystal glass.Lead crystal glass haikurudzirwe kudyiwa, kunyanya kana uchinwa zvinwiwa zvine acidic kubva kumagirazi ekunwira.Mutobvu uchanyungudika mumvura ine acidic, uye kushandiswa kwenguva refu kunokonzeresa chepfu yemutobvu.Makristasi asina lead haana zvinhu zvinotungamira uye haana njodzi kumuviri.Paunenge uchitenga girazi, unofanirwa kutarisa girazi risina mutobvu.Kana iri yemhando yegirazi, haina kukosha, asi inofanira kunge isina lead-isina.Pakupedzisira, pasi pekapu yakanyanyisa uye yakasimba.
