Because of its lead content, crystal glassware is stronger, heavier, and smoother than standard glass. The value of older and more highly decorated crystal glassware can range between $1,000 and $4,000—sometimes even more, depending on its condition and design.
What is special about Czech glass?
Extraordinarily inventive, Czech glassmakers also cultivated their own glassmaking techniques. Among the most significant were their unique contributions to the process of molding glass to create pressed glass beads, fire-polished finishes and mass production of their products.
What crystal is made in Czechoslovakia?

What is 24% lead crystal?
Generally speaking, any glass with the addition of Lead Oxide (PbO) is called crystal. Nevertheless, the composition must contain 24% or more lead oxide to be called full lead crystal. It is generally accepted that 24% lead crystal is the optimum percentage of weight, durability, and clarity.
Why are they called Czech beads?
When we say that Czech glass beads are ancient, we mean that they originated long before the Czech Republic, after which they are named. In the 1550s, the Czech Republic was known as Bohemia. Production of glass beads began in ancient Egypt, and many cultures have successfully adopted the practice over the centuries.
Does Czech glass contain lead?
Studies show that if a person were to drink from a lead crystal goblet every day for many, many years, a slight trace of lead may appear in their body. Although many types of glass do have minerals within their composition and sometimes as an outer covering, no, not all Czech glass contains lead.
