Panning for gold was also known as placer mining. Early miners sat by riverbeds, scooping wet soil into shallow metal pans. They swirled the pans, washing away the dirt to hopefully discover particles of gold. Though complex equipment was eventually invented, pans were still a useful tool to distinguish gold from dirt.
Gold has been used in dentistry since 700 BC.
