Metals

Of the 10 metal objects found in J6, only two are intact/whole. These are a copper-alloy needle i14 and a copper-alloy pin i30. Both were encrusted with soil and had oxidised surfaces. During the last excavation seasons we did have any specialist for metal conservation, waiting for next years. The objects are in the conservation lab. The other metal objects were taken for chemical analysis

Ceramics

The ceramic material that needs a treatment is mainly composed of vessels that are found broken in the ground but almost complete and can be reconstructed.

Seal impressions

Delicate sealing impressions that in 90% of the cases are taken to conservation, where they are left to dry and then are cleaned. Depending on the quality of the clay and on its hardness, they can be very hard and easy to clean, or extremely crumbly and difficult. To clean these, a magnifiyng lense and in some cases a microscope are usually necessary, together with scalpels, dental tools, needles.
