The latest installation by ceramicist and ocean advocate Courtney Mattison is Confluence (Our Changing Seas V), a porcelain coral arrangement produced for the US Embassy in Jakarta, Indonesia. The site-specific work features a vibrant cluster of coral structures at its center which turn stark white the further they are placed from the installation’s core. This shifting gradient references the rapid devastation caused to reefs as temperature levels rise and force corals to lose their colorful algae.
