The work of the Ceramics, Glass & Metals Section, British Museum, Department of Conservation & Scientific Research. Coin Morning. Roman coins are cleaned in formic acid. The corrosion is dense but thin with good detail preserved underneath. There are several thousand coins in this hoard and being able to use chemicals will speed up the cleaning process.
