Again, I'm joining in an excavation at the Hasankeyf Höyük site in Turkey now. I left Japan on 5th, and came here on 6th. My survey just started on 7th. As well as last year, I'm analysing residue samples from grinding stone tools. This time, I can conduct various sampling methods.
- Before unearthed and washed with water: I'm taking samples from stone tools before unearthed, and again taking samples after washed shortly. After they are unearthed, I'm taking soil samples beneath them as well.
- After unearthed, before washed, and on-site stored: These stone tools are kept on-site after unearthed. I'm examining starch extraction of them with 1.
- After unearthed, before washed, and stored with soils in our guesthouse: These stone tools were covered with a bag after unearthed, and kept in our guesthouse. I'm examining starch extraction of them with 1 and 2.
