Lead crystal is manufactured by adding lead oxide to molten glass. It is then machine cut into shapes. The higher the lead content the greater the “refractive index”, or in other words, the greater the sparkle. As the lead content goes up it becomes harder to form the crystal and therefore the price for higher lead content also tends to be higher. The maximum lead content is about 35%.
