Twilight chrome oxide (or sulphuric acid) and colorless natural jadeobjects in the same water, through the electrode in the object The surface is green. This kind of ochre only stays on the surface layer thicker and more stable than the brush color, and can withstand short-term wear, but the color is too yellow or too blue, it is very evil, making it difficult to accept. Dyeing is the process of acidification. The dyed objects are attached with a layer of impregnated dye. Under the high magnification magnifying glass, most of them have dye deposits. The ochre is hardly plated with a layer of impregnated dye at high temperature and high pressure. The thickness of the magnifying glass is uneven, and it also has precipitated deposits. There is little difference between dyeing and cabin color. The false color dyed can not withstand the strong sunlight, and can not withstand the heat of baking. The retention time is very short. It does not exceed 10 months at normal temperature. Will automatically fade or disappear. If it meets with strong acid and strong base, Burmese jade bracelets it will be completely corroded. Baking color Due to the collection of multi-body minerals, the coloring ions in the jadeite composition have Cr, Fe, Ti, S, Cl and other elements.
