Treatment and Conservation Study for Two Archaeological Spears from Dhamar RegionalMuseum, Yemen
Archaeological iron artifacts are often covered with a crust, containing organic fibers, mineral particles, dirt, etc. Before conservation, this crust must be carefully removed. With traditional mechanical and chemical methods, there is an obvious risk of over-cleaning. These methods also increase the risk of the oxidized or primary corrosion layer breaking away which will lead to loss of information about the form of the object and other important surface details.
