Experimental Study on Enhancement Technique of Amber

According to the common varieties of amber products in the market and different temperature,pressure and atmosphere in the enhancement experiments,the amber samples from Kaliningrad,Russia,are treated into the golden ambers,red ambers,amber with the golden-yellow flower-shaped inclusions or red flower-shaped inclusions and old ambers,etc.The technical process,conditions and influence factors of the amber enhancement are also discussed.The results show that the technical process could be divided into 4 stages,i.e.preparation,opening the oven,enhancement and closing the oven.The golden amber products could be achieved by the purification technique,the red amber products could be achieved by the roasted colour technique,the amber with the flower-shaped inclusions could be achieved by exploding technique and the old amber products are achieved by the heating under the common pressure and slow oxidation.The influence factors of the enhancement technique of amber are summarized,including colour,transparency,size and conditions of temperature,pressure and atmosphere.
