"CT scans of a 16th century sword from Jena in Germany have revealed a name engraved on the blade, hidden by a thick encrustation of rust. The inscription reads Clemes Stam, the name of the Solingen swordsmith who made it. The blade was one of four surviving swords interred in the graves of the Collegiate Church in Jena where faculty, students and their families were buried in crypts between the late 16th and early 19th centuries."
"He enlisted the aid of industrial research institution INNOVENT e.V. to virtually break through the barrier. The EasyTom 150-160 X-Ray Micro& Nano-CT computed tomography scanner from the French manufacturer RX Solutions, available at INNOVENT since the end of 2022, represents a good compromise between sample size and resolution. On the one hand, relatively large samples up to 70 cm in height can be measured;"
A 16th-century rapier recovered from the Collegiate Church graves in Jena bore a rust-encrusted inscription that CT scanning revealed as Clemes Stam, a Solingen swordsmith. Four swords survived burial in crypts used between the late 16th and early 19th centuries and were recovered after the church was destroyed in World War II. University of Jena researchers investigated the finds for seven years. Archaeologist Enrico Paust enlisted INNOVENT and an EasyTom 150-160 X-Ray Micro & Nano-CT scanner to virtually penetrate heavy corrosion. Layered imaging exposed a sheath, welded steel construction and copper-sheet letters 0.6 mm thick inlaid into the blade.
