title: Identification of graphite in tissue sections.
abstract: Graphite can be identified in tissue sections by its birefringence, in spite of its black color, and by its resistance to conventional incineration, but it is removed by exposure to radiofrequency-excited oxygen plasma. Amorphous carbon is removed by conventional or radiofrequency incineration.
