What is Pigment Black and Which grade of black are used in paint and coating formulations?

 What is pigment black?

Black pigments derive from carbonized wood, bone, oil, tar, resin — or any organic material. The pigments are made by burning organic materials, like wood or oil, and collecting the carbonized remains, such as charcoal or soot. These are then ground into a powder.

 Although carbon black pigments look similar on paint surfaces, under a microscope their particles have different shapes depending on the material used to produce them.
