Will crystal break easier than glass?
The addition of up to 30% lead oxide, ( though most manufacturers are reducing it to 24%, the legal minimum to be called lead crystal ), gives crystal glass a high index of refraction which makes it sparkle when cut at sharp angles, is softer to cut, and gives the glass a distinctive long lasting ringing tone when it is struck gently with a hard object like a fingernail. The lead may under very extreme conditions leach out into acidic beverages, like white wine or orange juice ( if stored over night in a fridge for instance). The glass is also more fragile and subject to temperature shock: Crystal glass will often break when cold water is poured into a hot glass or vice versa. Glass is a liquid in the sense that it does indeed flow, but it flows over an extensive period of time. The difference between a crystal and glass, is that a crystal has a homogenous solid formed by a repeating,

Whats the difference between crystal and glass... as in crystal versus glass champagne flutes... I know glass is a viscous liquid but what is crystal?
Crystal is defined legally by a UK British Standard BS 3828 of 1973 and the EU Crystal Glass products directive 69/493 EEC of the 19th March 2002, Gazette No 24700 . The Refractive Index by UK and EU law, must be not less than 1.520, and the density must be of at least 2.54 g/cm2. If lead is present, to be called "Crystal Glass" it must contain 10% at least of zinc, barium, or potash, alone, or together. (In the USA, only 1% is needed, which would easily be considered just plain glass by the UK.) Only Lead crystal, ( or Full Lead Crystal with over 30% lead) contains lead or other materials which modify the characteristics of the material. The same is true for other types of glass where the refractive index is changed by inclusion of other materials to make camera lenses etc. "Lead crystal" was a British invention discovered by George Ravenscroft and registered on the 16th May 1667, and financed by the Worshipful Company of Glass Sellers of London. The addition of up to 30% lead oxide, ( though most manufacturers are reducing it to 24%, the legal minimum to be called lead crystal ), gives crystal glass a high index of refraction which makes it sparkle when cut at sharp angles, is softer to cut, and gives the glass a distinctive long lasting ringing tone when it is struck gently with a hard object like a fingernail. The lead may under very extreme conditions leach out into acidic beverages, like white wine or orange juice ( if stored over night in a fridge for instance). The glass is also more fragile and subject to temperature shock: Crystal glass will often break when cold water is poured into a hot glass or vice versa. Glass is a liquid in the sense that it does indeed flow, but it flows over an extensive period of time. The difference between a crystal and glass, is that a crystal has a homogenous solid formed by a repeating, three-dimensional pattern of atoms, ions, or molecules and having fixed distances between constituent parts. Glass on the other hand, has molecules that are disordered but are rigidly bound.

How to tell if beads are glass or crystal?
It's not easy. If you have a lot of, say, 8mm bicones of both glass and crystal, you could weigh them (the glass separately from the crystal). The crystal should weigh more than the glass. However, if you want to tell Swarovski crystal from non-Swarovski crystal, there are a few characteristics to check. First of all, all Swarovski beads will be cut the same, whereas non-Swarovski beads will vary in cut quality, style, and facet placement. Second, Swarovski colors saturation will be consistent throughout each color and each bead. Non-Swarovski colors may fade or separate within the bead. Third, drilled holes in Swarovski beads will be centered, consistent, and not overly large in each and every bead. In non-Swarovski beads, drilled holes may be on an angle/not true vertical, may be 1mm or more in diameter, may not be centered in every bead, and you might see more than one hole drilled in, say, an 8mm cube. Finally, in the case of an aurora borealis finish, the Swarovski beads will exhibit a subtle iridescence, but the non-Swarovski beads will exhibit an obvious, coated iridescent effect.

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.

YES! Because when you heat the mixture of water and glass beads up at boiling temperature, the water will evaporate and leave the glass beads behind. =-)
