Paint Spheres
The paint spheres in this image are blue. There are two paint spheres stuck together in this image. The transpartent
vehicle is easily seen at the edges of the spheres. The pigment and the rutile opacifier are submicrometer in diameter and are difficult to see.
This particle looks dark except at the edges of the particle when only transmitted light is used.
Transmitted Off Crossed Circular Polarized Light and Reflected Darkfield Illumination
Definition/Function:
Paint spheres are created by spray painting or brush painting. More are produced by spray painting.
Significance in the Environment:
The presence of paint spheres indicates residues from painting. It may be associated with construction residues or be the result of a painting
activity alone. The presence of paint spheres may indicate a source for solvent odors.
Characteristic Features:
Associated Particles:
If this is part of a building construction residue then sawdust, plaster, magnetite spheres, and abrasive particles may be present. It this is
from a paint spray booth then spherical agglomerates of alkaline salts, organic residues, and pigment may also be present. If it is from a local
uncontrolled painting activity then the spheres will not be associated with construction or water scrubber residues.
