Abstract
A method of marking an industrial process material including selectively incorporating a luminescent marker onto and/or into the industrial process material in a trace amount insufficient to be optically detectable in the presence of ambient light but sufficient to be non-destructively optically detectable in and/or on the industrial proce material in situ in the field or on-site. The trace amount of the luminescent marker is used to track, identify authenticate the industrial process material for at least one of material control, inventory control, stock control, logistics control, quality control and pollution control.
