Ash from a nearby Industrial Fire
                This is ash and char from a Maria fire along with debris
                  from the local industrial environment. Much of the material
                  that burned was a fiberglass composite. The resin had burned off of much of the
                  composite so glass fiber was common in the downwind direction from
                  this fire. This glass fiber is coated with ash and soot from the fire. Agglomerated
                  soot particles (the black fuzzy edged particles) are another
                  major component in this assemblage from the fire. The black sphere right of lower
                  center is from welding and not the fire.
