Collections Manager Christa Deacy-Quinn recently conserved a Christian wall altar with Pieta and Last Supper motif (1995.16.0001A). The wall altar’s glass was covered with masking tape, likely for stabilization during transportation years ago. Unfortunately, once peeled, it became evident that significant amounts of adhesive would remain on the surface of the glass.
To combat this, Christa used a heated spatula to slowly loosen and peel the masking tape from the surface. This allowed for the tape to be removed in full strips and minimized leftover residue. From there, a sponge dipped in 200 proof ethanol was placed on the glass to soften the areas of gummy adhesive. Christa then used a razor blade to carefully remove the now-loosened adhesive residue. Last, the glass was cleaned to remove any streaking and smudges. The wall altar is now ready for future display or further scholarly research!
