This is a piece of coked cotton fiber that resulted from high temperature but lack of oxygen in a house fire. The
characteristic twist is still preserved in the charred fiber. It was collected as part of a tapelift study of a home after "remediation".

Significance in the Environment:
Coked cotton fiber in a home may be from the top of an incondescent light bulb or a product of a fire where the amount of oxygen present is too low
to oxidize the carbon in the fiber. In this case there were many such fibers as a result of a fire in the home. The wireing in this home was
insulated with cotton/tar insulation and much of it burned in the area damaged by this fire.
