If you have many beautiful wine glazers and other products that have been inherited, you probably thought how to distinguish crystal from glass at home. If you broke like a dishes, it is easier to do this - the real crystal is scattered into a lot of small pieces, but the glass beats into pieces. But it is hardly known that you broke a high-quality thing will add you mood. So let's talk about how to deal with whole products that you can use for a few more years.
Sound that is difficult to confuse something
If you are slightly knocking down the crystal, it is squeezed. And this ringing will continue some time after contacting with the surface, as if it would hang in the air. The glass does not give such an effect: it sounds short, the ringing of him seems to be empty, not saturated, and it stops very quickly. Take several different options for dishes and listen as they ring - even without having a musical hearing, you can very quickly find the difference.
Also, the crystal can "stall" if they spend a wet hand over it. But this method is possible to realize not everyone. Take the fool, wet your fingers and spend around the edges - if you're lucky, a beautiful sound will appear. Then you can be sure that you are definitely not glass, because it does not have such properties. But if the product is "silent", do not hurry to upset - there are other ways to make sure that you have a crystal thing.
Heat Hand: Touch the dishes
Crystal is characterized by the fact that long does not become warm in human hands. This interesting ability was even used in antiquity. Riema rich people kept crystal balls to cool the palms when it was very hot on the street. If you will twist a glass or a vase in your hands for a long time, it will not all be very warm. The glass will show completely different properties: it will warm very quickly, repeat the temperature of the hands. It is very convenient to carry out this experiment, too, in comparison. Take the product that is accurately made of glass, and immediately hold it. Then do the same with the presumably crystal thing. If there is a strong contrast, you immediately notice.
Light and color: another way to decide on the material
If you enlighten the products well, you can notice various imperfections in them. Divorces that show how material behaved to frozen, very small air bubbles - it all says that in front of you ordinary glass. Crystal has such defects can not be. And the glass can increase the object, if you look through it. Crystal gives split. But this is also not always easy to check, because patterns often applied patterns, drawings - they are already distorted by an image of the object, so it is not easy to figure out.
Use for definition and bright light. If you bring a crystal vase to the sunlight, you will notice that it will start very beautiful and incredibly overflow. In the refractions of this game you can see different colors Rainbow. Glass responds to light more calmly and does not affect such beauty.
Can crystal cost cheap?
Price is another sign that can be added to the fact that we have already called. If crystal glasses cost suspiciously cheaply, we have almost one hundred percent probability of ordinary glass. Crystal has never been a cheap material. If you do not want to encounter fake, buy products only in stores that will value with your reputation or are official representatives of proven brands. Then you can buy a thing that is not ashamed to show to guests or convey to descendants.
Probably, not many, acquiring products from a mountain crystal, think about whether it is not fake to him. Such a question may not arise due to the fact that rhinestone is not considered, but relates rather to semi-precious minerals. However, fraudsters will not be dreamed, so it would not hurt to arma their knowledge on how to distinguish a rhinestone from the fake.
And to be more accurate, then how to distinguish a rhinestone from glass, because it is from it, as a rule, it is forged by virtue of the external similarity of rock crystal and conventional glass.
Rhinestone - how to distinguish:
First, it is worth remembering that the hardness of the mountain crystal is high, it is much harder glass. Therefore, if you try to scratch the mineral with something sharp (knife, scissors, needles, etc.), then scratches on a mountain crystal will not remain, unlike glass;
Due to the same, described above, any chip or scratches on the product from a mountain crystal should not be;
Despite its hardness, rhinestone refers to fragile minerals - putting a certain force, it can be broken. However, in this case, it is possible to distinguish it from the glass. Glasses, as a rule, scattered into small fragments, the mountain crystal is broken into several parts, and sometimes it is simply split into two;
Answering the question of how to determine the mountain crystal, it is worth saying that there should be absolutely no extraneous inclusions within the mineral. Mountain crystal is a pure mineral, so no bubbles, dust, should not be lanes. To determine their presence, you need to consider the stone at a good light;
There is one natural feature in mining crystal, which also plays when determining the naturalness of a mountain crystal. Despite its high thermal conductivity, this mineral is cold. This means that it is always cold to the touch, but if you squeeze and warm it in the palm of your hand, it warmer quickly, but in a few seconds after the palm is swallowing it will be cold again. It is worth remembering that even when the stone heats up, it will be cooler to the temperature of your body. This property of rock crystal distinguishes it from glass, which, when heated, takes the body temperature, and it will be cool later;
Speaking about how to distinguish rhinestone from diamond, then the diamond has shine much brighter than that of crystal, he plays all the colors even with a very bright light. However, if you are mistaken in favor of diamond when choosing, despair, of course, it is not worth it, because diamonds are more expensive.
Here are the basic rules of how to distinguish a mountain crystal, how to determine the rhinestone and how to distinguish a rhinestone from glass.
And yet, if there were doubts, it is better to seek expertise to the experienced jeweler.
Do not forget that
Almost no solemn event is without a stall of glasses. Modern technologies in the manufacture of dishes for special occasions has reached such heights that few can distinguish glass from crystal.
You will be surprised, but from the point of view of chemistry, all, and festive, and casual dishes are made of glass. The difference is only in the composition and proportions of ingredients.
The most popular and affordable can be called sodium-lime glassconsisting of quartz sand, soda and lime, which are the most affordable natural resources.
If alkaline components are replaced by boron oxide, then it turns out more durable borosilicate glass, patented by the brand name "Pyrex". Such glass is not afraid of strong heating and is usually used to produce heat-resistant dishes.
Crystal - This is a special type of glass, manufactured with the addition of lead. Moreover, in the US, crystal is considered glass containing only 1% of lead monoxide, and in Europe - 30%. Best exclusive glasses are made of crystal handmade, for example, elite glasses Riedel.
Crystal glass or lead-free crystal - Last technological development of glasses and other drinking dishes. Instead of lead oxide, recognized by harmful global health organizations, other ingredients add to such glass, allowing to improve glass quality. Formula of the composition of U. different manufacturers may differ. But in general, the crystal glass is more adapted for everyday and professional use Due to its strength and resistance to mechanical exposure.
For example, Spiegelau glasses are manufactured from the crystal glass. The high quality of the components used makes Spiegelau products more brilliant, transparent, durable, resistant to shocks, safe for use in the dishwasher, compared with other glasses made of cheap components.
Crystal glass contains at least 10% metal oxides. Potassium compounds improve the reflection, transparency, make the glass brighter and brilliant. Zinc increases chemical resistance, it is thanks to his glasses of Spiegelau, you can safely wash in a dishwasher, without fear that they will sweep.

So how to distinguish lead crystal from glass?
It is worth noting that in some cases, glassware from glass (more precisely crystal glass) is made as workshops, which only special examination can make a conclusion about its composition. After all, the crystal glass has the same melodic ringing and crystal transparency, as well as traditional crystal.
Choosing the dishes in the store site pay attention to the product characteristics. We are designed by the manufacturer's instructions and indicate the material from which the glasses are made. You can choose glasses of the desired quality using the directory filters.
How to distinguish a product from ordinary glass from a product made from crystal? To begin with, let's try to figure out what is each of these materials.
Glass is, as a rule, the material is artificial, because in nature it is extremely rare, after such infrequent natural cataclysms, like a volcanic eruption (volcanic glass) and a meteorite fall. In all other cases, glass has an artificial origin.
Pure rhinestone is a variety of colorless natural quartz having the shape of a hexagon pyramid (icicles). Translated from the Greek "Krystallos" - ice. Crystal in the cavities mountain breeds ("Crystal cellars") and in voids of lava deposits. But it also happens in quartz veins ("crystal coffins"), limestone rocks and slate.
There is also a so-called artificial crystal - glass with lead in certain proportions. In each country, the permissible amount of lead, so that the glass can be called a crystal, different. In Europe, for example, no more than ten percent, in the USA - enough and one. There are also such definitions such as lead and high-grade crystal, which differ in the percentage of lead content.
How to distinguish glass from crystal not in laboratory conditions and without hemological equipment.
The most important difference is in such a physical property as thermal conductivity. If you attach the palm to the glass, it will quickly warm and become warm. Crystal will remain cool, no matter how long they did not hold it in warm hands. IN Ancient Rome Patricia even used for cooling in the heat of hand Crystal balls.
If you spend the wet fingers along the crystal surface, then a clean sound will appear, resembling the ringing, but the glass does not work for such "sound".
Crystal, even processed, solid, rather than glass. Therefore, various damage and scratches to detect on it will not be able, even if it scratch it with a steel tool. But it can easily leave a mark on the glass, even with a slight effect on the surface. In order to break the crystal, certain efforts will be required.
But the presence of gaseous bubbles or foreign inclusions indicates that the usual glass is in front of you. Mountain crystal may include only cracks and stamps.
In the production of glass, it produces so-called swindles - lines for which a viscous liquid substance flows. When the light passes through the glass, these lines can be seen. In the crystal of these lines you will not see.
The glass has a uniform thickness of the entire surface and therefore has a property slightly increase the items when you look through it. Looking through a crystal, no changes in the size and forms of things is noticed.
Mining crystal has such a property as a strong split. For example, if you take a crystal ball and put on the edge of the sheet, the edge is split. Such an effect is definitely impossible to achieve, having spent this experience with a glass ball.
Rhinestone has a high refractive index, thanks to which it differs from the glass with a special glitter on the light and the color game.
There is another important difference that there is no glass - it is a "crystal" ringing. If you knock together two products made from crystal (it can be chandeliers or glasses), you will hear transparent, ringing, long, increasing resonant hum, not characteristic glass.
If you still have doubts, it is necessary to determine the authenticity of the crystal, it is better to resort to the help of expertise.
