Over the years I have often been inspired by Ammonites which were a marine species that evolved throughout the Mesozoic era between 252 and 66 million years ago. Evidence of their existence comes to us through Fossils and the evolution of Ammonites can be traced by their appearance in rocks of different ages. Ammonites are a theme I have been exploring through different techniques in enamel for many years. During that time work has evolved as I explore new ways of working. The pandemic in 2020 allowed me to take time out to develop new techniques and ways of working and Evolution arose out of this strange and difficult time. They comprise cloisonné enamel on silver using fine gold or silver wire over engraved silver. The silver surrounds are engraved to echo patterns in the rocks that contain them.
