Recovery specialists need to have a clear sense of the pros and cons of existing treatment options before they can respond effectively.

This study evaluates the physical effects of drying waterlogged archaeological wood using supercritical carbon dioxide as compared to air drying and the polyethlene gylcol (PEG)/freeze drying method.

NCPTT received a final report from a PTT Grants project, “Protocol for Emergency Washing, Drying, and Sterilization of Historically Significant Books” by the University of Utah’s Marriott Library.

When Union ships sunk the English blockade runner Modern Greece off the coast of North Carolina in 1862, Confederates at nearby Fort Fisher wasted little time in salvaging munitions from the vessel. Nearly 150 years later, what they left behind is helping make history in preservation research.

A new preservation technique involving the use of supercritical fluids to dry waterlogged archaeological wood will be investigated and compared to current preservation treatments.

Eric Shindelholz, formerly The Mariners’ Museum, successfully concluded his grant research and submitted his final deliverables regarding his project to investigate the use of emerging technologies for drying waterlogged archeological wood artifacts.
