The types and advantages and disadvantages of crystal lamps How to choose and identify crystal lamps
More and more crystal lamps are used in modern home decoration. The decoration of crystal lamps gives the home a refined and elegant feeling. However, in the process of home decoration and renovation, people do not have a special understanding of crystal lamps when choosing crystal lamps. , So it’s not impossible to start. What are the types and advantages and disadvantages of crystal lamps? How to choose and identify crystal lamps? Let's follow the editor of Benwei lighting to get to know it.

3. All copper crystal lamp:
Advantages: beautiful color, good texture, high-grade, long use time, not easy to oxidize and change color.
Disadvantages: higher cost.
4. Zinc alloy crystal lamp:
Advantages: Good mechanical properties at room temperature, abrasion resistance, fine polishing effect, and smooth surface.
Disadvantages: poor corrosion resistance, prone to micro-deformation after long-term use.

The above is a brief introduction about the types, advantages and disadvantages of crystal lamps. I believe that after the above introduction, everyone will have a further understanding and understanding of the types and respective characteristics of crystal lamps. Of course, there are many crystal lamp products on the market. How to choose and identify crystal lamps? Let's take a look at the following introduction:
How to choose and identify crystal lamps:
1. How to buy crystal lamps:
1. Crystal cutting accuracy:
The precision of crystal cutting is directly proportional to the result of the refraction of the crystal. The crystal cut by the computerized method is accurate and symmetrical. Regardless of the shape, it can reflect the dazzling color.
2. The purity of the crystal:
The higher the purity of the crystal, there will be no cracks, bubbles, water ripples and impurities in the crystal, and it is crystal clear and transparent, and it can play the best optical performance, so that the light passing through can refract the beautiful color and the uniform and convergent seven-color spectrum. (Rainbow).
3. The crystal is generously polished:
The appearance is severely polished, and the cut surface of the crystal is smooth and polished, shining brightly, thereby enhancing the reflection of the cut surface.
4. Crystal lead oxide content:
High-quality crystal products, the city accepts full-lead crystals, and the lead oxide content is not less than 30%. It is a pure material that can emit sparkling and bright colors.
5. Hole of crystal chandelier pendant:
If the holes of the crystal chandelier pendant are not scaled, favorable edges, abrasion, and different sizes will appear, which will not only affect the surface of the crystal lamp, but also accidentally collapse, causing the crystal chandelier pendant to fall from the ceiling, causing injury and injury.
2. How to identify true and false crystal lamps:
1. Seeing:
In the process of formation, natural crystals are often affected by environmental influences and always contain some impurities. When observing the sun, you can see faint uniform and small horizontal stripes or catkin-like substances, while fake crystals mostly use inferior crystal ballast and glass ballast. Smelting, polishing, coloring and imitating, without uniform stripes or catkins.
2. Tongue licking:
Even in the hot summer days, when you lick the surface of natural crystal with your tongue, you will feel cold and cool, while fake crystals will not feel cool.
3. Light:
Natural crystals are placed upright in the sunlight, no matter from which angle they are viewed, they can give off beautiful brilliance, while fake crystals cannot.
4. Hardness:
Natural crystals have high hardness, so lightly scratching the jewelry with gravel will not leave traces; if there are streaks, it is a fake crystal.
5. Check with polarizing lens:
Turning 360 degrees under a polarizer is natural crystals that appear to be bright and dark, but fake crystals that do not change.
6. Check with two colors:
Natural amethyst has dichroism, while fake crystal has no dichroism.
7. Check with a magnifying glass:
Check under transmitted light with a ten times magnifying glass, and the bubbles that can be found can basically be regarded as fake crystals.
8. Check with hair strands:
Putting a crystal on a hair strand, the human eye can see the double shadow of the hair strand through the crystal, it is natural crystal, mainly because the crystal has double refraction.
9. Detect with thermal conductivity meter:
Adjust the thermal conductivity meter to green 4 grids to test gemstones. Natural crystals can rise to 2 yellow grids, while fake crystals do not rise. When the area is large, it rises to yellow one grid.
