Many friends will encounter a lot of questions about the selection of amber when buying amber. Let's sort out the related issues below, but the following experiments are either not done or less, so as to avoid damage to amber.
1, sound; no inlaid amber chain or beads in the hand gently twitching will give a very soft and slightly dull sound. If the sound of plastic or resin will be crisper.
2, experiment; natural amber texture is very light, when you put it (without any inlay) into the water it will also sink to the bottom. But you don't have to worry about it. You will add dissolved brine to it. When the concentration of the salt is greater than 1 to 4 (1 part salt, 4 parts water), the amber will slowly float, and the fake amber will not float.
3, aroma; amber when rubbing only a little smell that is almost unseen, or simply can not smell. The amber that rubs to produce a scent is called "Samper". Generally, amber will only emit a loose scent when it is burned.
4, ether experiment; regenerated amber with high temperature pressed with amber powder, although the appearance is very close to natural amber, but if a little ether is applied, after a few minutes there will be a feeling of sticky and dissolved. However, I have checked a lot of my amber and put it in ether for about 2030 minutes.
5, eye observation; this is a trick to identify true and false amber; as long as you are familiar with - naturally there will be such a skill. The texture, color depth, transparency, and refractive index of true amber will change with observation angle and illuminance. This feeling is not found in any other substance. Just as we identify true and false people, such as superb artists can create a vivid figure of the wax, "just to the real thing" is just a talk, no matter how good the wax figure can not escape our eyes. As long as you have a favorite amber more than three colors and more than three months, no one can deceive you. Amber is transparent but very moist, not as unobstructed as glass, crystal, or diamond. Fake amber is either very transparent or opaque, with a color that is dead and fake. The fake amber interior is artificially made? "Amber flower" is very glaring, and it will feel a cold and chilly light. After a long time of contact with amber, it can be intuitively recognized by the intuition. Just like the identification of true and false people, even the best wax figure I believe You will also recognize it effortlessly without any effort.
6. Hardness test; when the needle is gently slanted at the angle of 20-30 degrees (when you think it will not harm the amber), you will feel a slight violent feeling and very fine powder residue. If it is a plastic or other substance with different hardness, it is either stuck or sticky or even stuck in.
7, acid-alkaline; true pure natural amber is quite resistant to the normal daily acid and alkali, because a lot of amber produced in the Baltic Sea is salvaged from the sea, they have spent hundreds of millions in the sea itself In the year, if we are not resistant to acid and alkali, we may not see it.
Opical Fiber Concrete which is New, safety and high quality
* Low-loss optical window in the light-visible area, and ability to transmit visible light from end to end, but not including ultraviolet or infrared light
* The impression given by traditional concrete is always murky, but this dark-colored, lifeless concrete may be about to become a thing of the past. combining traditional concrete with fiber optics cable can produce transparent concrete. Combining the fair-faced concrete technology with light-guiding materials, through product research, the light-transmitting concrete is made into garden building products, decorative plates, decorative blocks, transparent concrete bricks, wallboards, etc
* As long as the light is shining on one side of the light-transmitting concrete (monochromatic light or 7 color light), it will be able to see these lights (non-guided infrared light) from the other side of the concrete. These lights can be both chaotic and heavenly like the star in the sky; it also can be arranged in different shapes according to actual needs, such as characters, text, drawings, etc.. Because the concrete itself has solid, heavy-duty, thermal insulation, light and transparent materials, and concrete composite can be made into garden construction products, decorative plates, decorative blocks, can also be used to make a variety of building materials.
* Light-transmitting concrete has a good working performance and a wide application prospect, as follows:
- Light transmission concrete light guide material is evenly distributed and has good light transmission performance. It can transmit visible and infrared light of different wavelengths, which greatly saves the general architectural lighting loss. It is a kind of green and low carbon building material. Works of different textures and colors have significant architectural energy-saving and decorative effects.
- Light-transmitting concrete has good thermal insulation properties and is used in accordance with related materials. It can be used in indoor fire escape, night guidance, and other special fields, and improves the safety of buildings, especially high-rise buildings.
- Compared with ordinary concrete, the light-transmitting concrete's bending strength is greatly improved, and various shapes can be made according to building requirements, which expands the practicality and applicability of building materials.
- Light-transmitting concrete This type of wall itself has a high appreciation value. It has great potential for application in hotels, restaurants, villas, and other buildings that require decoration, and provides a material basis for further improving the architectural aesthetic effect.
* No conductivity or heat transfer(Through the fibers no electrical power is sent, they remain always cold )
* Reduced energy cost
* No electrical hazard
* Long life-time
