Zusammenfassung:A calcined solid drawing material may be capable of drawing a line excellent in color development and transparent while having a high strength regardless of a black core or a colored core. The calcined solid drawing material may include a skeleton core including at least an extender and a binder component, and a drawn line permeability T of the drawn line is 0.8 or more, as calculated by Equation (I):T=(L*w−L*b)/(L*b−L*p)  (I),wherein L*w is brightness of a drawn line written on white paper, L*b is brightness of a drawn line written on a black paper, and L*p is brightness of the black paper.
