The inclusion of at least 24% lead oxide in the composition is required by law for crystal to be called full lead crystal. The lead lends brilliance and weight to the product. Crystal without lead is still crystal, i.e. clear glass, however, it is more commonly perceived as &quotglass". The lead also make the crystal softer and more conducive to cutting. This is why the lead crystal is cut and for the most part, the unleaded crystal is not cut.
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.
Crystal glass is made differently with a different chemical composition (lead oxide is added). It is then cut either by hand or by machine to create facets and/or designs.

When lead is added to silica to make a crystal vase, it creates lead crystal glass. This type of glass is known for its brilliance, clarity, and weight. The addition of lead also makes the glass easier to cut and provides a distinctive ringing sound when tapped.
Most of the time it will. Good crystal always will. You can tell crystal from glass by lightly tapping the side of the glass, vase, or item. When you do this you will get a ringing sound from crystal and a "thump" sound from glass.
From the English word, Crystal means "clear, colorless glass" sometimes cut into the shape of a gemstone. The English word is derived from the Greek word 'krystallos' which means "ice".
Lead glass is made with lead oxide PbO this makes it dense. It also has a higher refractive index than ordinary glass. It is sometimes called "lead crystal glass" and has been used to make cut glass ornaments and decanters. There is a lead poisoning risk from drinking wine that has been stored for long periods in lead crystal decanters.
