Pech de l'Azé IV - Bordes' Collection

---

There was also a significant portion of both the stone and bone assemblage (roughly 9 percent, or 7,500 objects), primarily from the last two years of excavation, which was not washed. The principal issue with this material was the deterioration of the artifact labels. Each artifact was wrapped in foil and the ID number for the piece was written in pencil on masking tape that was then wrapped around the foil. With time, however, the tape looses its adhesive properties and becomes separated from the artifact. This had happened already with a small portion of pieces (less than 50).

Over four years, all of the unprocessed material was washed and labeled.
