The Emperor Nero bought a young and strong slave a relatively small piece of green amber. But in our time, amber lost the price. Modern chemical processes have reduced the price of amber.
So even in ancient times craftsmen learned to transform the usual amber green. Most of the stones cracked from the heat of unrefined olive oil, but the color of the amber pieces was changed to green.
Good effect is observed when the dry heating of amber in conditions of limited access of oxygen. Heated stone tightly wrapped in foil and placed in the oven. After processing, the amber becomes transparent and the glass literally glows Golden-green color.
In modern times green amber is everywhere. The difference in the chemical composition of ambers from various fields, determines the variety of stone processing technology.
Applied multi-step aging in heated gaseous and liquid environments. Is the saturation of fossilized resins with metal ions. Intensive radiation hard electromagnetic spectrum allows to achieve the effect of luminescence in the solid rock.
The researchers, however, say: the most attractive green color of amber is obtained not by the introduction of impurities, and high temperature exposure. Occurs under high temperatures of atomic aggregation to change light transmission of the resins. Light waves are of the greatest length (red) are absorbed by passing through the array of the light takes on a green tint.
