Charred Wood from a House Fire
This is a piece of charred Douglas fir (upper) and a
hardwood from the structural wood used in this home. This particle
was collected on a tapelift taken on the second floor of a home that had a fire in
the basement. This was carried upstairs by the
chimney effect through the stairwells.

Definition/Function:
Charring or coking of wood tends to retain the structure of the wood. As a result the
genus or even the species of the wood can often be determined
from an examination of the structure still evident. There is a reduction in the size of
the structures of about 20% typically.
Significance in the Environment:
Many types of wood are used in a wood structure building. The studs and structural beams
in a wood building are often Douglas fir or Pine. This
wood is often the dominant type of charred wood in the burnt building. The finish woods
are generally hardwoods though Cedar and Pine are also used
as a common paneling in some regions.
