Artefact Handling At ADMAT's Maritime Archaeological Centre.
During this field school project, a number of artefacts were examined. Two iron concreted cannon balls from The Tile Wreck and one from The Island Wreck were examined, then the concretion was removed and the artefacts were further examined. Small ballast stones from The Island Wreck were cut open and examined under a lope prior to being sent to ADMAT-FRANCE for identification.
One session which the Team enjoyed was the part where we examined some of the larger iron concretions from The Tile Wreck. From X Ray analysis conducted in Toronto, we know that most of the tools or iron items were now Ghost Concretions with voids. These had been created by the iron leaching out of the object forming the concretion. In time all the iron was dissolved leaving a hollow creating a ghost of its former self. Two box carpenter plane blades were cut and the residue removed and cleaned to reveal a section of the items. As a result of this we now know the object was not what we thought it was.
