A viscous, pitch-like ink mixture made from the soot produced from burning wood. It was used as a water-based ink. Depending on the material from which the soot was derived, bistre varied in tone from yellow-brown to almost black, with beechwood generally believed to produce the best quality and the most attractive color. The most important use of this colorant was in watercolor painting.
