Crystal glasses are not made out of crystal. They're made of regular glass in which the calcium is replaced with lead oxide or zinc, causing them to sparkle more than the usual type of glass.
What is an advantage of crystal vases over glass vases?
Crystal vases have thicker walls than those of glass vases. These thicker walls give an advantage over glass vases for breakage. Glass vases are also harder to clean than crystal vases, as spots will often show up more on glass vases than on crystal vases.

How do you identify a waterford lamp?
With so many fake waterford items made, identifying genuine waterford lamps can be difficult. Look for a gold sticker with green seahorse emblem on the bottom, or look for "waterford" etched into the bottom. To tell the difference between a glass fake and a crystal genuine, check for thickness, light, cut, and weight. Crystal is thicker than glass, crystal is clear while glass has a slight yellow or green tint, glass has rougher edges while crystal has a more smooth cut, and crystal is heavier than glass.
Why was the crystal made of glass?
The question is somewhat of a misnomer. "Crystal" and "glass" are contradictory states. A crystal has its molecules in a regular, orderly, repeated pattern. There are exactly six major potential patterns, each representing a possible way of stacking (the most obvious being "cubic" -- symmetric in 3 dimensions at right angles). Glass, on the other hand, is random and chaotic. Glass is formed when a molten material cools too quickly for its pattern to have time to be built. Historically, the word "crystal" was also used to refer to one specific type of crystal, namely quartz (silicon dioxide), also known as "rock crystal". AND "crystal" was used incorrectly to refer to decorative glass with a high lead oxide content, which makes it unusually brilliant and so reminded people of rock crystal. Thus items like candle holders and stemware are made of that type of glass, because it can be cast or blown into shape and is especially beautiful. And occasionally crystals are simulated by casting them out of glass, because that is much simpler than growing them.
