May 7 1999: Turning the posterior part of the skull
The posterior part of the skull was cleaned for clay today. We used a box with soft material to protect the fragile inner side while we removed the burlap and plaster from the outside.
Some of the bones are now already finished. Here is the lacrimal bone.
