Calcined Bone

When bone is burnt by a fire it can undergo a range of changes in appearances, such as calcining. Calcining, characterized by its bright white colour, is caused when bone is burnt at a higher temperatures. The bone can shrink, become more white or chalky in appearance, more fragile and more likely to fragment into smaller pieces. These pieces of calcined bone were collected during the summer of 2017. Calcined bone indicates the presence of a hearth at the site.
