Museum no. M.120C-1929
This plaque imitates those once used to form the sides of a casket or box. It was made in around 1900 and was decorated by etching, a technique popular in Germany during the 16th century for decorating steel locks and armour. With etching, the craftsman covers a piece of metal with an acid-resisting substance such as wax, then scrapes a design with a sharp tool and immerses the metal sheet in acid. The exposed metal corrodes, revealing the design.
