Work has been progressing nicely out in the Tank Farm. After a week in Tank 1 with the copper alloy artifacts, we refilled the tank with fresh solution, covered it back up with a tarp and moved into Tank 6. Tank 6 and 5 (which we were into this week) hold wrought iron artifacts. They all received a through cleaned via dry ice blasting, which is rapidly becoming one of my new favorite things.
One of the most exciting things about dry ice blasting these artifacts is that removing concretion often reveals previously hidden features. This has been the case for two artifacts in the last two weeks. The first was one of the stanchions off of the turret.
