There are generally two ways to see whether the jade has been pickled: 1, take some high-definition pictures and enlarge them on the computer. Usually you can see the acid etched reticular acid lines. 2. Check with a ten-fold jewelry magnifying glass to see if there is any acid etching on the surface of the jade blank. See if the crystal structure or fiber structure in jade has been corroded by acid through lighting.
As long as you take a photo with a purple flashlight, you will know that pickling must be injected with glue. If the stone has a luminescent fluorescence reaction, it is pickling. If you don't have a purple flashlight, you can use a money detector, which also has purple light.
/Look at the color of the pickled jade bracelet. Experienced people can observe directly with the naked eye. Its surface color is unnatural. 2/ Weigh the acid-washed jade bracelet, and the internal structure will become loose. When you weigh it with your hands, you will feel floating and there will be no feeling of "pressing your hands".
First of all, strong acid and alkali solutions are corrosive. After the jadeite is soaked in these strong acid and alkali solutions, the surface will be pitted and the structure will become loose. The surface will be called "corrosion pit", and the light will diffuse reflection, which does not look like the glass luster of natural jadeite after polishing.
Sulfuric acid and hydrochloric acid can not change the structure of jade at all. So what you said doesn't affect at all.
