This past week, the Monitor conservation staff began screening concretion and corrosion products removed from the interior of the turret over the last 10 weeks (see previous posts and video links on the main page). As with any archaeological excavation, we want to make sure that even small objects and fragments are recovered for future study and interpretation. This being said, we have opted to use a process called wet screening. Under this technique, material types of various sizes are separated out while at the same time washed by a steady stream of water to remove loose sediment and rust. The additional washing makes the identification of small artifacts easier and speeds up the overall screening process.
