A micromorphology sample has been prepared cutting through the floors of the western room (Space 158) and central floor area (Unit 8296) of Building 3. The block is ready to be carefully cut from the matrix which still holds it. The thin layers of repeated floor plaster can be seen at the base of the block, a thick layer of dark foundation material, and then on top a thick layer of beige packing covered by thinner white plaster floor layers on the floor of Space 158. From the slides that will be created from this block by Çatalhöyük project micromorphologist Wendy Matthews, the history of the building and many more pieces of information can be "read" under the microscope.
