A recent study has provided crucial insights into the manufacturing techniques used to create the Nebra Sky Disc, an artefact thought to date back 3,800 years to the Early Bronze Age. The analysis challenges claims suggesting the disc could be a modern forgery. Researchers revealed that the disc was crafted through an elaborate “hot forging” process, involving at least ten heating and hammering cycles at temperatures exceeding 700°C, according to Christian-Heinrich Wunderlich, a metallurgist cited by Live Science. Discovery and Ongoing Debate The study was published in Scientific Reports on November 21. Unearthed in 1999 near Nebra, Germany, the 12-inch bronze disc, adorned with gold symbols thought to represent celestial bodies, has been the subject of considerable debate. Initial reports lauded it as the oldest known depiction of the sky. However, questions regarding its authenticity arose, including theories suggesting its discovery site might have been staged to enhance its market value. Experts involved in the study recreated a replica using Early Bronze Age techniques, reportedly. The metallographic comparison between the replica and the original disc …
