The conference I presented at was The Pan American Ceramics Congress and Ferroelectrics Meeting of Americas (PACC-FMAs). This meeting happens every two years and materials scientists and engineers make up the largest group of attendees.

Experience the fear, the awe, and the excitement during this extraordinary time in our nation’s history.

On December 31, 1862, USS Monitor was caught in a storm and sank 16 nautical miles off Cape Hatteras, North Carolina, in more than 230 feet of water. It is believed the vessel went down stern first, turning over so that its revolutionary 120-ton revolving gun turret separated and became pinned under the ship on the seafloor.

We can handle a lot of heavy lifting with our staff, but sometimes we need to call on outside experts for help. Such was the case with No. 3746, a Japanese mini-submarine designed by Nishimura Ishimatsu. We needed to lift the sub onto a custom cradle and relocate it.

Amphorae are terracotta containers used for trade as their unique shape allowed them to fit snugly together in a ship’s hull. Since the Neolithic period, this shape has been in use and migrated to Europe during the first millennium BCE.

This treatment is a “re-treatment.” Occasionally, we’ll have an object that needs to be re-treated for various reasons. In this case, the Wellington boot was on display in our Monitor Center gallery. It is one of two boots from USS Monitor excavated from the turret and is the most complete of the pair.

The Monitor crew is busy with spring cleaning. Dry ice cleaning, that is. Last month we tackled Monitor‘s skeg assembly.
