Time Team Surveyor Steve Wilkes explains why mapping is an important part of archaeology.

Video description: 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.
