Crystal FAQs

What is the difference between glass and crystal?

Lead Oxide is added to the glass mixture to create crystal. Crystal will give you that ping on a glass or the rainbows in a room. 24% Lead Crystal, with its exceptionally high perceived value, has been sought after and treasured for generations, and remains a status symbol even today.


Are there different types of crystal?

Yes.

To be considered crystal, material has to have at least 7% lead oxide in the mix.

To be considered Full Lead Crystal it needs to contain a minimum of 24% lead oxide. The lead adds the brilliance and the weight to the glass body. Our Asfour crystal is full 30% lead crystal.


 

What is Optic Crystal?

Optic Crystal is 100% Lead Free and extremely hard. It is this hardness that provides the basis for the brilliant cuts and bevels, as well as the ultra high polished surfaces. This is a newer material that is sometimes used in place of Full Lead Crystal due to the fact that it is a much less expensive material to produce.
