Metal. Corrosion due to wood acid exposure. Comments: Continued exposure to acids from the MDF board backing caused lead corrosion. Drawing at left shows condition prior to installation. On display in a show case with a MDF board bottom and backing. Compared with the drawing to the left in the show case, showing the outline of the amulet when it was inserted to the case, it can be seen how it since then has corrodes away in the middle. The amulet is from a Danish museum. Image credit: Morten Ryhl-Svendsen, IAQ in Museums and Archives. Permission for use provided via email by M. Ryhl-Svendsen 11/2019.
