Non-lead crystal: Crystalline can be described as a really exclusive glass.Glass generally consists of a mixture of sicica,potash,cullet,calcite which is melted at high temperatures.Adding metal oxides(zinc,barium)significantly increases the brightness,brillance,clarity.The right crystalline must contents more than 1% of these metal oxides.Densi...
