Problems

• Divers do remove metal artifacts and largepieces from the sea without any conservationplanning

• Electrochemical Methods are not in use byprofessional C-Rs for the cleaning orstabilization of metals (lack of know-how, andtechniques for diagnosis and monitoring ofobjects undergoing treatments)

• 2003 Removal of a WWII German JunkersAirplane off the coast of Leros island

Approach to Salvage the Object

• Move object away from Port to Museumand create an exhibition place to protect it

• Carry out documentation and analysis ofthe object

• Build a replicate of the wheel

• Try to stabilize using Impressed Current• RAISE MORE MONEY for conservation of

the object!!!!!!

Treatment of collection in TEI

• 25 Artifacts

• Copper & Iron Alloys, Composite(wood, textile, leather)

• Surface layers: marine concretions & corrosion products

Stages of conservationtreatments by students

• Documentation

• Diagnostic analyses (X-RayRadiography, XRF, SEM)

• Chemical & mechanical cleaning of concretions

•Stabilization with chemicals

• Corrosion Inhibitors & ProtectiveCoatingss

Problems with the application of electrochemical treatments

• It requires constant supervision

• Students cannot undertake such projectsat an undergraduate level?

• Work can only be carried out in final year(internship and/or undergraduate thesis) orat Masters’ level training

Future Plan

-raise national funding to promoteresearch and conservation of marine

artefacts removed from the sea-promote in-situ conservation of 

shipwrecks and tourism of 

underwater parks-create a conservation laboratory for

marine artefacts on Syros
