As we all know, the tea perch (especially black tea perch), chameleon, and the change of light intensity and angle of the backwater in Burmese amber present a variety of colors, and the diversity of colors alone is more complex and diverse than that of blue perch.
Everyone is amber, why is there such a special change in The only Memph? Today Xiaobian will talk to you about this problem.
(1) Black tea per
In fact, the reason for the discoloration of amber is nothing more than which: such as what light source changes, spectral wavelength changes, amber reflection refraction of light, amber penetration attenuation of light and so on!
However, after careful observation and research by Xiaobian, I feel that the photoreserving reaction of Burmese amber is more biased towards the Tyndall phenomenon!
(1) Tea Perk
Tyndall effect: When a beam of light passes through the colloid, a bright "pathway" in the colloid can be observed from the vertical direction of the incident light, a phenomenon called the Tyndall phenomenon.
I believe that everyone often has such an experience, in the early morning, in the dense woods, you can often see a column of light passing through the branches and leaves, similar to this natural phenomenon, that is, the Tyndall effect. This is because clouds, fog, and soot are also colloidal, but the dispersant of these colloids is air, and the dispersing matter is tiny dust or droplets.
This principle may explain the cause of discoloration of tea and chameleons.
In order to verify this, it is actually very good to do something similar to stone rock. Using a flashlight, a beam of light in the dark, and letting the optical fiber penetrate the amber, this effect will occur.
Compared with the more obvious, Liu Qing and JinPo class do not have this situation. Only chameleons, green tea, black tea, yellow tea and other teas will exist, Burmese amber tea by the length of light retention time, color, water purification, etc. to identify, the identification of the Tyndall effect is also very important.

There is also a special phenomenon of Burmese tea is "light absorption", that is, if we illuminate the amber body with strong light and immediately remove the light source, there will still be a few seconds of residual light and shadow effects on the amber.
This phenomenon is generally called "absorbing light", also known as Galasan.
And this "light absorption" phenomenon, not only tea perk, some other gold perk, golden brown, brown red perch, will also appear such a situation. This situation may not be noticed by many people, but in fact, it is an excellent way to distinguish amber from plastic and other imitations.
There is also a more special kind of amber in Burmese amber, this amber golden yellow with a redish inclination, under the illumination of natural light, the amber surface will have a faint blue-white or greenish-white machine oil light, this amber is known as: black tea permeather chameleon.
This amber is a very rare species of Burmese amber, rarer than blood permeation, and it is called a chameleon when illuminated by violet lamps, and the fluorescence will be biased towards white and blue.
Black tea perme chameleon, yellow and red in natural light, the color is clear and translucent, under the black will be more inclined to the glow of the gemstone, the surface appears white, green and blue change color, the whole amber looks magnificent, unpredictable. If you use strong light to illuminate, there will be a purple band of light inside, which is what we called the Tyndall phenomenon earlier.
These unique performances are not available in other ambers! It can be said that in terms of the singularity of the color appearance alone, the Burmese chameleon is superior to the dormant.
