Archaeologists in the Heddernheim section of the German city of Frankfurt have excavated and conserved an intact wooden cellar—including its five-step staircase—datingMuseum conservator Thomas Flügen describes this four-month, 15-step process as requiring innovative solutions that included injecting the entire surface with epoxy resin, covering it with silicone rubber and gypsum laminate, and then cutting it into 33 sections before taking it to the museum. There, it was reassembled and bonded back together by placing glass fiber laminate on the underside.
