It depends on the distance and the shape of jade. Generally speaking, it won't break if you just drop it on the glass.
It looks bad from the outside. The jade pendant knocked on the glass counter. For jadeite, it is more serious to look bad from the outside. Because jadeite is a brittle gem, it may not be visible from the appearance, but its internal structure is composed of many small crystals.
In addition, the line that can only be seen 30 times cannot be lit. .
You can't scratch it under normal circumstances. The first possibility is that unless it is strong, it is deliberately destroyed at a special angle, because as we all know, the hardness of jadeite is 5 Mohs higher than that of glass. Another possibility is that the jade bracelet is fake and synthetic.
If those downstairs think that things with high hardness and low impact hardness must be broken first, congratulations to those downstairs, you haven't studied physics. Hardness can only show that under the condition of friction and no relative collision, a small hardness may be damaged. It's like an artificial diamond cutting glass.
The texture of jadeite is generally brittle, and it is easy to crack when it falls to the ground. Jade fell to the ground, generally speaking, to protect you from disaster. If the appearance is good, I suggest you take a closer look inside. Some hidden cracks in jadeite are hard to find. Some jadeites have no cracks outside, but there are cracks inside. I'm afraid you haven't seen them before.
The windshield of a car collides from the inside or the outside according to whether the scattered objects collide from the inside.
The windshield of a car will not fall apart when it is broken. Because automobile glass contains a polymer material-polyvinyl butyral. Polyvinyl butyral (PVB) polymer materials often have quite good toughness. When they are impacted by external forces, they can dissolve energy by changing their own shapes without breaking.
Automobile glass can be divided into laminated glass and tempered glass. Now most of them are laminated glass (front bumper). The front windshield of an automobile is laminated glass, and its structure is divided into three layers or laminated glass, that is, glass on both sides and super glue in the middle. Its main function is that car glass will not hurt people when it collides like tempered glass! .
After the windshield is broken, the starting point of the broken glass presents a typical "butterfly spot" shape, as shown in the above picture. It is obvious from the thickness direction that there is a stone in the middle of the thickness direction, so it can be concluded that the fracture of glass is caused by the "self-explosion phenomenon" of tempered glass, not by external force.
Seek the correct maintenance method of jadeite.
Fuel saving is the most important maintenance method. Some jadeites will have cotton threads and spots after being left for a period of time. Practical experience has proved that applying proper amount of oil can eliminate cotton threads and spots in a short time and restore the original appearance of jadeite.
Maintenance method of jadeite: clean it regularly to avoid contact with oil stains, so as not to affect the surface color; Avoid collision with hard objects to avoid cracks; Often worn on the body, it is moistened by human body at constant temperature, absorbs skin oil and sweat, and gradually forms patina.
Jade can be soaked in water for a period of time, then gently wiped with a soft brush, and finally absorbed with a soft paper towel.
Jade maintenance methods: artificial cultivation, hydroponics and enclosure cultivation. This kind of maintenance is that when jade is worn, it contacts with human skin and absorbs the oil secreted by human body. In the long run, it will make jade brighter.
Maintenance is as follows: Regular cleaning First of all, friends who wear jadeite should clean jadeite regularly. The method is simple: soak jadeite in clear water for 30 minutes. If its surface becomes dirty due to long-term wear and tear, gently scrub it with a small soft brush after soaking.
It is best to put it in a jewelry bag or jewelry box to avoid friction or impact. If it is high-grade jade jewelry, don't put it on the table, so as not to accumulate dust and affect the brightness. Try to avoid contact with perfume, chemicals, soap and human sweat.
How to identify the quality of jadeite?
1. A very simple way to judge the quality of jadeite is to listen to the sound. Tap the jade gently with a gadget and listen attentively. The sound of natural jadeite is crisp. Generally, it is judged as a good jade with a crisp and melodious voice, and a bad jade with a deep silence.
2, look at the color Jade is very rich in color. When identifying good or bad, the fuller the pure jade, the better. Generally, the best color in jade is green. When looking at the color, it is best to observe it in natural light, so that not only the color of jade can be seen clearly, but also the uniformity of color distribution can be seen.
3. Look at the identification method of planting water jadeite. When identifying the quality of jadeite, you can distinguish it from the type of water. Generally speaking, the older the water, the better the water head and the better the quality of jadeite. It seems that the transparency and hydration degree are very high, and obvious fluorescence can be seen under light, while the jadeite with poor quality has poor water head and weak permeability.
4. Method 1: Is there a testing organization nearby? The certificate issued by the testing organization is the simplest and most authoritative identification method. Method 2: It is one-sided to identify jadeite by its characteristics. Let me explain it in detail below. To identify yourself, we must first know the characteristics of jade.
