Calcified bone is displayed in ground sections. Bone from which the calcium has not been removed is sawed into relatively thick slices. These are then ground thin and smooth, which destroys the organic components, like bone cells and blood vessels. The dye, e.g. basic fuchsin, infiltrates the resulting empty spaces which previously contained bone cells with their processes. This renders the architecture of the lamellar bone visible. The ground section is more or less intensively stained, depending on how well the dye has infiltrated the empty spaces.
