The glass and crystal products are seen everywhere like paperweight, door knobs,necklace etc. Both of them looks so beautiful. However, besides the price, how to identify the glass and crystal.
In fact, the ingredient of glass and crystal is actually very simple. Basically, crystal is the byproduct of the combination of lead and glass which means that pure glass is completely devoid of any lead. After adding lead, the glass become crystal which has new properties. The most obvious difference is the weight. Crystal is often much more weight compared to glass since the lead is a heavy metal. Instinctively. Adding lead to glass will make a weightier compound in crystal.
The wight is a way to distinguish the glass and crystal. To the eye, the most obvious difference between glass and crystal is the diffraction of light inside. Without lead, glass will allow light to go through,but when lead is added, light begins to diffract inside causing that rainbow of color that is most often associated with crystals. A prism is the most obvious example of a crystal diffracting light. Also,when glass furnaces were filthy, to add lead assured clear and transparent glass. But for really nice crystal, it is need to add lots of lead. That is why the real crystal is much more expensive.
In a other hand, the softness of crystal is different with glass. In adding to being a heaving metal, lead is also famous of being very soft and malleable, Where glass usually breaks with the application of too much force, lead allows crystal the ability to be etched, shaped, and chiseled. And as with each property, the more lead there is, the softer the crystal will be.
However, How many lead in glass can be considered crystal? The legal transition from glass to crystal varies from country to country. in the United States of America, anything above a 1 percent lead content is considered crystal, ,whereas in Europe, anything with a 10 percent lead content is considered crystal.For that matter, any glass may contain trace amounts of lead and be considered crystal. Further, there are some dealers who will not use the term crystal and instead refer to any glass with a lead compound as lead glass, since glass does not, officially, have crystalline properties. But for the most part, the combination of lead and glass is considered crystal. And as mentioned before, more lead means a heavy, softer, and more diffracted crystal. Put simply, the higher the lead content the higher quality the crystal, while glass means no lead.
In our daily lift, knowing the intricate differences between glass and crystal can go a ling way when we purchase one. But there are a tenet: buy what you like. with cleaner furnaces and glass - lead is unnecessary - and with only a 1% barrier to call glass 'crystal' - it really makes it inconsequential.
