The article discusses the problems encountered with the conservation of objects uncovered from a 14th-century BC shipwreck found at Ulu Burun, (Kas) Turkey. After a brief description of the storage and recording methods on-site, the conservation considerations are given. The work of cleaning, desalting, drying and stabilizing the artifacts is discussed in five cases where particular problems were encountered: an example of a composite material, a copper-alloy sword with wood and ivory inlays; a waterlogged metal, a silver bracelet; waterlogged elephant and hippopotamus tusk and tooth ivory; glass and amber beads; and finally, tin ingots and artifacts.
