Soot luminosity is visible from the combusting spray. The dark region outside of the combusting spray is the schlieren effect from hot combustion products at the edge of the spray—not soot. The combusting spray penetrates more quickly than the vaporizing spray because of dilation of hot combustion products within the spray.
