When I visited the Georgian National Museum in Tbilisi in early 2014, I was deeply impressed by a documentary showing a craftsman working on an enamel piece. I learnt that this person was Ermile Magradze, an art scientist, who dedicated decades of his life to rediscovering the lost technique of making «Georgian Cloisonné Enamel». The specialty of this Georgian technique compared to the European technique is that the creation of the individual colour chambers is achieved by a silver thread soldered onto a metal plate.
This special goldsmithing technique originated mainly in Byzantium and Georgia in the II century a.d. and was practised until the middle of the XV century. Due to historical circumstances this sophisticated technique was lost.

My wife Nina Gamsachurdia, Georgian and art historian, could establish contact to Ermile Magradze and arranged a meeting in his workshop in Gori. Meeting him was another time I was overwhelmed by the fact that he is not only a profound art historian, but also an exquisite craftsman who hand made all the necessary tools based on his knowledge of ancient times. 
The aim of his research was to rediscover the process of creating the Georgian type of Cloisonné Enamel, using an accurate selection of raw materials (various gems, silver and others) and his own time-accurate tools. 

Eventually Ermile Magradze achieved his goal. As a sign of recognition, he received a doctorate from the University of Tbilisi in 2021.*
