1. Processing soil samples through flotation, Ahenkro, 1994

Description:
Banda Research Project team member Mensah Listowell processes soil samples from Makala Kataa using a bucket flotation method. The large head pan is filled with water into which he lowers a wire mesh basket filled with soil. As he gently shakes the basket, the soil dissolves and passes through the basket mesh. He uses a small mesh ladle to skim the seeds and charcoal ("light fraction") that float to the top of the water inside the basket. The "heavy fraction" which remains in the basket after the soil has washed away will be set aside to dry. It will be sorted for small artifacts like beads that may have been missed during excavation. Ahenkro, 1994.
