Clip: Season 1 | 2m 23s
Students suit up in goggles and gloves when PhD candidate Heather Law Pezzarossi brings them rusty old nails to practice conserving. These artifacts are from a real archaeological site, giving the students a rare and exciting opportunity to practice iron conservation. They snip, clip, and brush away chunks of rust, and then use tannic acid to preserve the metal.
