Penelope Clifford holds a BA in Archaeology from the University of Western Australia, and became interested in patina 15 years ago while studying artefacts from an historical archaeological site at Cossack, Western Australia. Over and above her interest in patina, as an archaeologist, and natural history researcher, her research encompasses mediaeval and historic buildings and churches, the voyages of ancient and historic explorers, Indigenous middens and, in the natural sciences, tidal-flat ecology and wetlands. She is currently conducting further research into the complex formation of patina on glass.
