The Effect of Preservative Solutions on Hull Plate Samples From the USS MONITOR.

Abstract

The temporary preservation of artifacts recovered from the USS MONITOR are described. an alkaline solution of sodium benzoate with biocide was effective in preserving a section of wrought iron hull plate for many months. The effects of several preservative solutions on small sections of MONITOR hull plate were studied. Sodium benzoate and nitrite were found to be effective with trisodium phosphate, but ineffective in the absence of an alkaline pH buffer. Chloride seawater salts were extracted at rates conforming to first-order kinetics. However, extraction was not complete under static conditions, and additional chlorides appeared upon exposure of the specimens to humid air. Descaled specimens were more stable in the atmosphere than those with the scale intact. (Author)
