Crystal chandeliers are divided into many types according to their different materials. Crystal chandeliers made of different materials have their own different characteristics.
Glass tube crystal chandelier: modern and beautiful, good light transmission, crystal clear, good high temperature resistance, easy to break, restricted in shape and difficult to clean.
Iron crystal chandelier: unique style, beautiful shape, low cost, but easy to fade or rust.
Copper crystal chandelier: beautiful color, good texture, high-grade, long-term use, not easy to oxidize and change color, and the price is relatively high.
Zinc alloy crystal chandelier: good mechanical properties, wear resistance, fine polishing effect, smooth surface, poor corrosion resistance, and prone to micro-deformation over time.
Cutting accuracy: The accuracy of crystal cutting is directly proportional to the refraction result of the crystal. The cutting must be accurate and symmetrical so that the crystal can reflect the dazzling color.
Crystal chandeliers
Purity: The higher the purity of the crystal, there will be no cracks, bubbles, water ripples and impurities in the crystal, and the appearance should be crystal clear and transparent, and the light will be better reflected.
Polishing: Only a serious and strict polishing process can make the crystal cut surface smooth and shining bright, and strengthen the reflection effect of the cut surface.
Lead content: High-quality crystal products, with lead oxide content of not less than 30%, can better emit bright colors.
Pendant hole: The hole of the crystal chandelier pendant should not have favorable edges, wear and size, so as not to affect the surface effect of the crystal lamp.
During the formation process of natural crystal, affected by environmental factors, it will contain some impurities. When you observe the sun, you can see light uniform and small horizontal stripes or catkin-like substances, while fake crystals are mostly smelted by inferior crystal ballast and glass ballast. It has been polished, colored and imitated, without uniform stripes or catkins. Natural crystals are cold and will feel cold and cool to the touch, while fake crystals do not feel cool.
Natural crystals are placed upright in the sunlight, no matter which angle you look at, they can give off beautiful brilliance, while fake crystals cannot. Natural crystals have high hardness and will not leave traces when scratched with hard objects, while fake crystals will leave scratches. Place the crystal under the polarizer and rotate it 360 degrees, the natural crystal is changed like bright and dark, and the fake crystal is unchanged. Check under transmitted light with a ten times magnifying glass. If bubbles are found, it is a fake crystal.
