1. Tarisa pachiratidzo: Girazi risina kutungamirira rinowanzoita potasium ine potassium, kunyanya mhizha yepamusoro uye ine logo pane yekunze yekuputira.Lead-containing glass ine lead, kureva kuti, crystal glassware inowanikwa pane mamwe masupamaketi nematafura, zviri mukati melead oxide zvinogona kusvika 24%.2. Tarisa ruvara: Girazi risina kutungamirira rine dhipatimendi riri nani pane girasi rekristaro rinotungamirira, rakadai semhando dzakasiyana-siyana dzezvishongo, magirazi ewaini ekristaro, marambi ekristaro, nezvimwewo. Yakagadzirwa nemutobvu-ine girazi.Zvinoenderana nezviri muchikamu, ndezvenyu 3. Tarisa kupikisa kupisa: Girazi rinogona kuramba tembiricha yakanyanya, asi kazhinji kuramba kupisa nekupisa kunowanzo kuve kwakashata.Lead-free crystal glass igirazi rine high-expansion coefficient.Inonyanya kupikisa kupikisa kupfuura kupisa uye kutonhora.Kana iyo yakagadzirwa neiri kufashaidza tii nemvura inofashaira mune yakanyanyisa inotonhora lead-isina girazi, inongoita kuputika.4. Kusimbisa: Lead-containing crystal glass products inorema zvishoma kana ichienzaniswa ne-lead-free crystal glass products.
