This was by no means a normal restoration. Restorer Hartmut von Wieckowski tells gruesome tales about the condition of the mammoth bull from Pfännerhall, whose bones had been “completely overtreated” with synthetic resin during an earlier restoration. The animal was found in 1953 during brown coal mining in Braunsbedra in the Geiseltal in Saxony-Anhalt together with the bones of a young mammoth. However, parts of the young mammoth’s bones were destroyed during excavation, but the approximately three-meter tall (shoulder height) adult mammoth could be recovered in large parts. The animals lived around 200,000 years ago.
The exhibition of the mammoth bones in the State Museum of Prehistory in Halle/Saale immediately became a sensation and a magnet for visitors. And it has remained so to this day. Now the restored mammoth is one of the stars of the current exhibition “Climate Forces”, which deals with climate development as a “driving force of evolution”, as the subtitle says.
Before the first exhibition, the mammoth bones were plastered and molded for a replica. Around the year 2000, the original bones were “provisionally plastered, supplemented with synthetic resin and molded. As were the uncleaned surfaces,” says Hartmut von Wieckowski, who has spent the past two years mainly removing these synthetic resins. “My job was to restore them to their original condition, in addition to cleaning and conserving them.” Even the tusks made of mammoth bone had been smeared with synthetic resin in an uncontrolled and charmless manner. Epoxy or polyester resins are suitable for bonding, but are poor for preserving and supplementing bones. The resin shrinks, becomes brittle and porous and leaves cracks. It is also highly flammable, which, in addition to the development of gas, promotes the destruction of irretrievable cultural assets. Von Wieckowski partially blocked off the bone structures and used a polymer plaster of fire class “1”, which is easy to process and color. “I left partial age additions in order to document incorrect restoration decisions,” says von Wieckowski.
