1. Kapu yegirazi yesodhiyamu uye munyu ndiyowo kapu yemvura yakawanda yegirazi muhupenyu hwedu.Zvikamu zvaro zvakakosha silicon dioxide uye sodium oxide uye calcium oxide.Rudzi urwu rwekapu yemvura inogadzirwa nemuchina uye kuvhuvhuta kwemaoko, iyo yakaderera mumutengo uye zvigadzirwa zvakajairika muhupenyu.Kana iyo sodium uye lipid glassware inoshandiswa sechinwiwa chinopisa, inowanzoda kuderedzwa painobuda mufekitari, kana zvisina kudaro kapu inoputika kana kusiyana kwekushisa kwakanyanya.
2. High borosilized glass cup, girazi iri rakatumidzwa zita rehuwandu hwe boron oxide.Maseti etii uye matepi anoshandiswa netii anogona kutsungirira shanduko mukusiyana kukuru kwekushisa pasina kuputika.Asi girazi iri rinotaridzika rakatetepa, rakareruka, uye rakashata.
3. Crystal girazi mukombe.Rudzi urwu rwegirazi chigadzirwa chepamusoro mugirazi.Nekuti kune zvakawanda zvesimbi zvirimo, kupeta kwake uye kubuda pachena kuri padyo nemakristasi echisikigo, anonzi girazi rekristaro.Kune mhando mbiri dzegirazi rekristaro, lead crystal glass uye lead-free crystal glass.Lead crystal glass haikurudzirwe kudya, kunyanya kunwa zvinwiwa zvine acidic zvinowanzoshandiswa.Maelementi emutobvu anonyungudutswa kuita zvinwiwa zvine acidic.Kushandiswa kwenguva refu kunokonzeresa chepfu yemutobvu.Lead-free crystal haisi chinhu chinotungamira uye haina ngozi kumuviri.
