Some people say that burning jadeite can distinguish between true and false;
Someone asked, can I wear jadeite when I soak in the hot spring?
Today we will explore:
Emerald and fire, or rather, the relationship with high temperatures.
01. Identify the true and false
There is a widely spread saying that if the jadeite is burned on the fire, it can be distinguished whether the jadeite is A goods, because if it is B goods, the glue inside will be melted.
It sounds like a lot of sense, but I personally don't recommend it.
When it comes to fire, there is one word, melting point.
The melting point of jadeite, after high temperature testing, is about 800-1000 degrees. At this temperature, the jadeite will begin to melt into a glassy shape.
What is the concept of 1000 degrees?
The maximum temperature in the center of the burning cigarette butt can reach 800 degrees.
Although the melting point of jadeite is high, it is another matter if it has to be burned with a high temperature fire.
02. Destruction & beautification
Just like this example of burning an emerald bracelet with a gas stove, after high temperature burning, the bracelet directly changes color and is scrapped.
After cooling, it breaks with a gentle break.
From the burned cross-section, no residue and coke were found in the gaps, still had a glass luster, and no large areas of shedding and honeycomb-like appearance were seen on the surface.
The black part is the black smoke that natural gas remains on the surface. After removing the remaining black fume material, the fracture is still fibrous, without any change, which is enough to prove that this jade bracelet is A goods.
You know, the flame temperature of natural gas is divided into 3 segments, which are 900 degrees, 1300 degrees and 1800 degrees, if you use the fire of natural gas to verify the true and false, then I am afraid that there is no real jade in the world.
It can be seen that the method of using fire to identify the true and false is not only crude and unreliable, but also harmful to people.
Even if it seems to have a beautifying effect of burning red, in fact, there are many drawbacks.
Burning red is a treatment method for red and yellow jade. During the heating process, due to the loss of part of the adsorbed water, the iron filled in the jadeite gap will gradually crystallize from the original colloidal form and convert into a small collection of fibrous or needle iron ore microcrystals, so that the color of the jadeite becomes more vivid.
But on the other hand, the gap between the particles of jadeite will also be exposed, there will be many small dry cracks, the texture will become thicker, the transparency will decrease, etc., compared to the natural red jade, the value of the red jade is not high.
03. Daily maintenance to prevent high temperature
Now we all know that high temperature is not friendly to jadeite, which will make the water head of jadeite worse, the germplasm dry, the structure destroyed, and the fissures increase.
Therefore, in daily wear, it is necessary to pay attention to high temperature prevention.
First of all, when cooking or grilling, avoid contacting the emerald with high temperatures or open flames. If the environment is very hot, it is best to remove the jadeite jewelry in case it is damaged.
At the same time, friends who like to steam saunas should also remove the jadeite before entering the sauna, so as not to heat and shrink the jadeite, causing internal cracking.
When going out to play, if it is a place with strong sunshine, such as the seaside, try not to wear jadeite, one is to avoid being too strong sunlight, and the other is to collide with jadeite when playing.
In addition, for long-term jadeite, it is necessary to regularly wash the soaked water, and the jadeite that is not worn frequently should be carefully put away and placed in a cool, dry and ventilated place.
Beautiful and beautiful things, always let people feel pity and love, jade is the same, worthy of our careful treatment, careful care ~ people raise jade for three years, jade raise people for a lifetime ~
