    Group F dusts are carbonaceous, the primary dust in this group being coal dust. (*also coal dust and carbon black). These dusts have somewhat lower ignition temperatures than the Group E dusts and a layer of Group F dust has a higher thermal insulating value than the layer of Group E dust, thus requiring a more careful control of the temperature on the surface of the material.
