Do Not Migrate

NCPTT recently provided technical assistance to the Louisiana State Exhibit Museum in Shreveport regarding concerns about the condition of several archeological copper objects associated with the Gahagan burials that were excavated in the 1930s. The objects included a pair of long-nosed god masks, a copper hand effigy and copper/wood ear ornaments. NCPTT’s Jason Church, David Morgan and Mary Striegel, evaluated the chemical makeup of the objects using a portable X-ray Fluorescence Analyzer. They offered recommendations about display conditions and referrals to conservators who may assist the museum.
