1. Different materials:
1. Crystal glass:
is just a melting state mixture containing silicon dioxide.
2. Crystal:
is the crystal of the silica.
. Function:
1. Crystal glass:
The glass has only decorative effects.
2. Crystal:
In addition to the decorative effect, there is also a voltage effect.
three, nature:
1. Crystal glass:
refers to the extremely crystal utensils caused by cooking the glass, namely the artificial crystal.
2. Crystal:
one of gems, quartz crystals, which belong to the quartz tribe in minerals, and the chemical formula is SIO2.
The expansion information
Crystal glassware is derived from Europe. The main producing place is Germany, France in Western Europe, Czech Republics and Hungary, etc., each with its own characteristics. Crystal glass is made of silicon (Silica) and lead -oxide (subsequent lead crystals using other materials, such as potassium oxide, oxide, etc.). Degree cares about polishing technology plus quality.
The crystal is a crystal, which has high hardness (Mo's level 7), while the glass has low hardness (Mo's level 5.5). The crystal can be traces on the glass, and it cannot.
It is a good material for home decoration and gift whether it is crystal or crystal glass. Generally speaking, the price of crystals is relatively expensive. At present, the brand selling high -quality crystal glass on the market is mainly Swarovski.

The difference between crystal and crystal glass:
1. Different materials
Crystal is the crystal of silicon dioxide. Crystal glass is silicon (Silica) and lead -oxide (subsequent lead crystals use other materials, such as potassium oxide, such as potassium oxide , Oxidation, etc.) Cooking together, crystal glass is just a molten mixture containing silicate.
2, the effect is different
The glass has only decoration effects. In addition to the decorative effect, the crystal also has a piezoelectric effect. It has a special health effect.
3, the price is different
The unit price of the crystal is several times or even dozens of times higher than the crystal glass.
4. Different processing processes
The glass can be cast as hot, provincial and labor -saving, and low cost. Crystal is a crystal. After heating is melted, it cannot be reversed, so the heat casting method cannot be used, and only cold processing methods such as cutting can be used. rn扩展资料：rn20世纪50年代，前苏联和捷克等东欧国家就研制了无铅水晶玻璃，到了上世纪末，为了防止污染，无铅水晶玻璃更引起人们的重视，从最早The zinc crystal glass studied in the Soviet Union, the Czech Republic, etc., developed into multiple crystal glass such as 锆 crystal. Lead -free crystal glass include:
1, 钡 crystal glass;
2, zinc crystal glass; Crystal glass;
4, 锆 crystal glass;
5, mixed crystal glass.
This Crystal glass has a high refractive index, large color scattered, high density, and a thick texture. There is a sound of metal when knocking, and the sound of the remaining sound is beautiful. Crystal branch chandeliers and various lights have almost become luxury lamps for churches, venues, hotels, and high -end homes. Waterford is made of large chandeliers made of Windsor Castle and Kennedy Center. Reference information source: Baidu Encyclopedia-Crystal Glass
First, the material is different:
1. Crystal glass: just a melting state mixture containing silica.
2. Crystal: The crystal of the silica.
. Function:
1. Crystal glass: glass only has decorative effects.
2. Crystal: In addition to decorative effects, there is a voltage effect.
three, properties:
1. Crystal glass: refers to the extremely crystal utensils caused by the melting glass, alias, called artificial crystal.
2. Crystal: One type of gemstone, quartz crystal, belongs to the quartz tribe in minerals, and the chemical formula is SIO2.

The identification of crystals and glass
1. Wipe or wash the crystal crafts that you want to identify. After drying, touch the crafts with the tip of the tongue. If there is a cold sense, it is a crystal product. If there is a temperature, it is glass. During the test, try not to hold the sample or put the sample near the heat source (under the sun, the side of the stove) to avoid errors from rising the temperature of the sample.
2. Observe the crafts with a magnifying glass. Inside the glass, there are often vortex or curved curved line patterns caused by uneven melting, and there is absolutely no crystal. In addition, there are often many bubbles in the glass, and there are very few crystals.
3. For crystal balls, you can put it on the newspaper and look at the newspaper below from the top of the crystal ball. If it is glass products (including crystal glass), the handwriting on the newspaper will always have only one image.
4. Crystal glasses can be checked in the polarizer. The polarizer is adjusted to the right position. At this time, the vision is all black, and then the crystal lens is placed between the two polarizers. Do not strictly parallel the lens and polarizer. At the corner, then rotate the lenses.
5. When traveling out, the polarizer is inconvenient to carry, and can bring two polarizers (or two minimum photographs with polarizers) with two diameter less than 40mm. The person holds the glasses and puts it between the two polarizers. If there is a significant brightness change, it is a real crystal product. If the darkness does not change, it is a glass product.

There are four main differences, as follows:
1, different materials
The crystal is the crystal of the silicon, and the crystal glass is only a mixed mixture containing silicon dioxide.
2, the price is different
The unit price of the crystal is several times or even dozens of times higher than the crystal glass.
3, different physical properties
(1) Crystal is a crystal, which has high hardness (Mo's level 7), while the hardness of the glass is low, (Mo's 5.5 level), the crystal can be on the glass on the glass Drive traces, but instead.
(2) Crystal is the crystal, which has good thermal conductivity. It feels cold with the tip of the tongue. The glass looks warm.
4. Different processing processes
The glass can be cast as hot, provincial and labor -saving, and low cost. Crystal is a crystal. After heating is melted, it cannot be reversed, so the heat casting method cannot be used. It can only be used with cold processing methods such as cutting grinding.
The crystal hardness, not easy to wear, low glass hardness, easy to rub hair, good crystal stability. It will not change color for a long time, and the glass is easy to yellow.

standard
has no national and industry standards in China. The habits are divided into:
(1) high lead crystal glass PBO ≥ 30%;
(2) The mid -lead crystal glass PBO ≥ 24%
The development process
crystal glass has a long history. In ancient times, due to the large impurities of glass raw materials, the melting temperature was not high, the glass was not melted, and there were a large amount of molten sand and bubbles, air bubbles, air bubbles At the same time, there are many metal ions such as iron, manganese, and titanium in raw materials, and the glass is often opaque or translucent.
In the 13th century, the Venetians used a seli -impurities and levant -containing plant ash to melt into colorless and transparent glass.
15th century, the quality of raw materials has been further improved, and the pure alkali soda crystals in the pure quartz sand and plant ash boiling water in the lower reaches of the Ticino River; It is a kind of sodium and lipid crystal.
The difference between crystal and glass is as follows:
1, the essence of crystals and glass is different. Crystal crystal body has double refraction. The glass is an amorphous body, which reflects unparalleled. Therefore, you can clearly separate the two with a polarizer.
2, crystal and glass hardness. The hardness of the glass is lower than that of the crystal, so the crystal can always be engraved with glass, and the glass cannot be engraved.
3, the thermal guidance of crystals and glass is different. Crystal heat conduction rate is high, and glass thermal conductivity is low. Therefore, the crystal hand has a cool feeling, while the glass has a warm feeling.
Extension information:
Crystal (Rock Crystal) is a rare mineral, a kind of gemstone, quartz crystal, which belongs to the quartz tribe in mineralology. The main chemical ingredients are silicon dioxide, and the chemical formula is SIO2. When purifying, colorless transparent crystals are formed.
Glass is a non -crystal inorganic non -metal material. Generally, a variety of inorganic minerals (such as quartz sand, borax, boric acid, heavy spar, carbonate, limestone, long alkali, etc.) are used as the main raw materials. Auxiliary raw material.
. Its main ingredients are silicon and other oxides. The chemical composition of ordinary glass is NA2SIO3, Casio3, SIO2, or Na2O · Cao · 6sio2. The main component is silicate reinvantage salt, which is an amorphous solid of irregular structures. Widely used in buildings, used to transmit light, belong to a mixture.
