A randomly formed @P04433@ material and may be coarse, fine and/or @C01172@ in proportions depending on its origin. Soot consists of @V06600@ quantities of carbonaceous and inorganic solids together with absorbed and occluded tars and resins.
Note:
An unwanted by-product of incomplete combustion or @P04961@. Soot generated within flames consists essentially of aggregates of spheres of carbon. Soot found in domestic fireplace chimneys contains few aggregates but may contain substantial amounts of particulate fragments of @C01142@ or @C00974@. Soot from diesel engines consists essentially of aggregates together with tars and resins. For historical reasons, the term soot is sometimes incorrectly used for @C00824@. This misleading use should be avoided.
