Cooper was mined and used for implements during a period in the late Stone Age. He could have a great mass of cattle or a great mass of wheat, but these are not good treasures - you cannot carry them around. Egg took the Iceman's copper ax blade in his hand. The axe was the most important clue to the dating of the Iceman. The research on the body of the Iceman is being examined by 40 different research teams which work together on finding more information about life in the Stone Ages and for future information.
Extreme care is taken in studying the body.
The Iceman is wrapped in several layers of insulation in the cooling cell to keep the body under the same conditions as it was conserved in the ice. When the research team brings the body out to study, it is placed in a chamber with a stable micro-climate and studied at most for 30 to 40 minutes. After the usage is up the body is wrapped back with layers of insulation and replaced back in the cooling cell, where it has to stay for several days before it can be examined again. The care of studying and preserving the body are critical steps in keeping the body in exact condition as it was found. One major mystery about the Iceman is how the body preserved for more than 5,000 years, and if the cooling cell can give the body the temperature the natural surroundings gave him.
