What is even more glass and what is crystal? In various countries, the rule for determining what is crystal glass and what is different. For example, in America, just 1% of lead content in the glass so that we talk about moths crystal. It is generally understood as a crystal glass of high quality and either refined or enriched with lead glass.
According to European standards, glass goods containing less than 4% lead oxide known as "glass" when it contains more than 10% lead, we talk about crystal products containing more than 30% naming it as a high-lead crystal. Lead is added to the glass first, because the glass softens and adds his weight. This results in improved workability and then the refraction of light. Due to the breaking light falling on the surface of the rainbow colors. We also know crystal containing less than 24% lead, but not containing barium oxide and this again causes a high refraction of light.
