Description

Pressed charcoal sticks that have been soaked in linseed or olive oil. Oiled charcoal has been identified in 16th century Renaissance drawings (Stratis 1999). The sticks produce a deep black line in which the oil permanently adheres the charcoal to the paper. However, the oil can migrate into the paper usually producing a halo around the line that can darken with age. In some papers, the oil can also be seen on the verso.
