Simple flotation in water
combined with a submerged sieve is now standard practice for the
recovery of both biological and archaeological remains in the field.
Using a flotation tank in northern Syria
to recover charred plant remains from archaeological sediment at Jerf
Charred plant remains essentially seeds
and charcoal are collected in a sieve.
Residue which does not float and which is trapped on the submerged
sieve is then sorted for small animal bones and archaeological objects. Daniel
Helmer and George Willcox.
