Nitram Liquid Charcoal is water soluble, so you can adjust the values from very light to a deep, rich black. Straight out of the tube, it is as thick as oil paint - you could even use a palette knife. It dries very fast.

EXTRA FINE, EXTRA SMOOTH
Nitram Powdered Charcoal is milled to an extra fine, uniform 100µ particle size. It is smooth, velvety and consistent. It has no coarse or grainy lumps that can mar the surface of your paper. You can use a brush or a paper stump to create shapes and tones quickly and easily. The uses are limited only by your imagination!
