Treating copper and copper alloy artifacts afflicted with bronze disease remains highly important in the field of cultural heritage conservation. Doing so on remote archaeological sites poses particular challenges, especially with regard to sustainability. Existing methods of treating bronze disease using corrosion inhibitors may pose risks to the environment and to the user. The need for to develop sustainable practices is paramount across disciplines. This thesis will investigate propolis as a more sustainable option for the treatment of bronze disease on pre-corroded copper alloy coupons. Raman Spectroscopy and X-ray Diffraction Spectroscopy revealed that clinoatacamite and other copper chloride hydroxides were formed on the copper alloy coupons during pre-corrosion. Scanning Electron Microscopy was used to observe differences between the surface morphology of untreated and inhibitor treated pre-corroded coupons. Lastly, weight change experiments were conducted to assess the inhibitor efficiency of propolis on pre-correded copper alloy coupons. The results in this study do not indicate that an 100 ppm inhibitor solution of propolis is affective at inhibiting bronze disease; however, the hypothesis that propolis may demonstrate efficacy at higher concentrations should be tested in future studies.
