This project came in as a damaged copper mount, that had been used to showcase a tile panel, and replacement tiles from the same manufacturer as the original tiles. As you can see in the photographs, the panel suffered significant warping along one of the edges. Straightening it out was outsourced to a metal specialist. Only after that was it realized that the new tile panel has a slightly larger dimension and would not fit. A new copper panel was made to the correct specifications and the new tiles were put into place with a restorer’s adhesive. The original copper mount had a substantial bracket that allows it to securely attach to a  wall. This was transferred to the new copper mount.
The tiles are from Sant’ Anna in Lisbon, Portugal, established in 1741.
