Treatment of the prism Ashm 1911-405

This four-sided prism contains a frequently copied Sumerian literary composition, which is nowadays called the "Kesh Temple Hymn." Although the inner clay body appears to be in a relatively good condition, some areas on the surface became unstable. In the course of a recent treatment of the prism a loose fragment (highlighted) could be rejoined to the tablet. Since any supporting material was gone, the fragment needed to be lifted onto a modern fill. The surface of the prism contains many smaller cracks. In order to stabilise the surface and prevent additional fragments from falling off, a thin adhesive was applied with a micropipette to consolidate the cracks.
