How to visually distinguish crystal from glass.
What made chandelier from crystal or skillfully treated glass? At first glance, it is difficult to answer immediately, however it is possible. Visually, crystal and glass are very similar - however, they differ in production technology, and according to the characteristics. For the production of parts from glass, quartz sand, calcium carbonate, sodium or potassium carbonate are fused. Crystal is made from the same ingredients with the addition of lead oxide. To do this, use the sand peeled from the iron oxides, eliminating the crystal from an unnecessary greenish tint and giving it special purity and transparency. The lead oxide additive increases the refractive index and dispersion of light, increases the decorative qualities of crystal products, from a jewelry point of view - "color game", "fire". Moreover, the latter is almost a quarter (24%) in the total weight of the product, which causes the presence of crystal products of some "metal" properties - pleasant gravity, soft ring, silver shine and ease of processing and polishing. Possible supplement of barium oxide mainly increases the refractive index. The addition of lead oxide also increases the plastic properties of crystal and, accordingly, the possibilities for its processing - cut, thread, etc. Acquired transparency, strength, weight and gloss allowed him to give it a name by analogy with a mountain crystal.
How else to distinguish a crystal chandelier from her glass copy? If you take into your hands two at first glance, the same suspension, then glass is heated, and the crystal will remain cool: they have different thermal conductivity.

Crystal detail chandelier is not easy to scratch, damage. The addition of lead oxide gives crystal products greater strength. However, it is still very careful to handle crystal products: when the glass is blowing with large slices, and the crystal is broken into small fragments. On the glass over time, scratches appear, cracks, sweat. With a crystal, this does not happen - it is a more durable material.
If you look through the details of the chandeliers and see the flow lines - whisie, then in your hands the glass. In addition, if you look at any object through a glass item, the image will be slightly increased. Crystal will give a split object without increasing. In crystal items there are no air bubbles. In the glass, most likely, you will see them, but there is no present crystal. It is determined by the fact that the latter does not contain foreign inclusions. If you look through the crystal faces on the sunlight, then you can see the overflow of all colors of the rainbow. The glass chandelier will not have such a decorative effect.
Crystal products are characteristic of a clean, deep, growing ringing with the usual lung impact of two suspension, as well as when spending a wet finger on the surface. The glass chandelier does not have such a sound - when the sound is impact, the sound will be deaf, creaky and short. The "vocal" crystal abilities depend on the percentage of lead oxide. From this, its transparency, strength, weight, shine and other properties are. Crystal chandelier will be heavier than its glass copy.
And last: the real crystal chandelier must have a certificate of the manufacturer. How to properly care for the crystal chandelier, we set out in detail in our article "General cleaning: Wash all chandeliers in the house." But, many crystal chandeliers are high enough, they have a lot of weight, size and, often, complex design, so they put them in order, on time to change the burned light bulbs, cartridges - the task is quite difficult.
The using of one technical device is able to solve the issue of free access to the chandelier at any time at what height would be neither. This device is a light lift for a chandelier. The device is small in size with electric or mechanical control and calculated to omit or raise even a very heavy chandelier, the carrying capacity of individual models up to 5000 kg, lowers the durable steel cable with the chandelier, and after the cleaning is carried out up to the ceiling. Use the remote control to raise and lower the chandelier is easy and convenient.
The PAYTEX company has a successful long-term experience in working with light lifts for a chandelier of big weight. We will be happy to help everyone who needs it. Contact!
