Restoration of Historic Artifact
Panama Pacific Exposition Urn Conservation
San Francisco, CA

The Panama Pacific Exposition Urn is an ornate urn composed of gypsum. It is hexagonal in shape, adorned with cherubs and swags. Once a part of the 1915 San Francisco World’s Fair, it is now displayed at the San Francisco Conservatory of Flowers.

Prolonged exposure to the environment, biological growth, and air pollution contributed to the deterioriation of this historic urn. ARG Conservation Services performed cleaning tests, followed by a complete cleaning and application of a biocide and water-repellent coating to deter further biological growth on the stone’s surface.
