Crystal and glass are often thought to be the same, and the term is used interchangeably.  Both materials are similar in that they are usually transparent and they have the same rigid structure and feel.  They also make a sharp loud chime sound when struck.  So what exactly makes these two different?

There are few, including the molecular structure, which distinguishes the two.  However, when it comes to crystal wine goblets, the important difference is the concentration of lead.  The amount of lead found in crystal is significantly higher than in ordinary glass.

Anyone who has seen a crystal object will notice the way the light shines off it.  The reason for this is that the lead oxide alters the index of refraction of light.  Coupled with the crystalline molecular structure, the way the light gleans off of it is very beautiful.  If the crystal is very cut [like a diamond], the light will be able to refract more and show even more colors, which brings up another point – the lead in the crystal makes it “softer” and easier to cut, and therefore, easier to create intricate designs.

Given how there is a significant amount of lead oxide in a crystal goblet (at least 10%), people often associate this with the potential hazard of lead poisoning.  However, in almost all cases, it is perfectly safe to drink from crystal wine goblets.  Research has shown that lead from crystal containers can leak into liquids if given enough time.  If you are using having a drink of wine from every so often, you are not in danger of lead poisoning because the wine probably is not sitting in the crystal long enough to leech harmful levels of lead.  Here is an article that explains it.  As long as you are not storing your wine or any other liquids inside a crystal decanter, you will be fine.

Needless to say, these are much more expensive.  However, they add a lot of character at dinner parties.  They can be used either as a display or to serve your “more important” guests.  Be sure to get a matching set if you are going to use them.  They come in many shapes and act as good white wine and red wine goblets.  The style and illuminating colors of crystal wine goblets are sure to impress anyone.
