The present invention relates an indicator system for assessing a reduction state of unconsolidated material that includes a delivery tube defining an interior chamber, and a substrate disposed within the interior chamber and including a reactive coating thereon. The reactive coating is at least partially removable from the substrate upon exposure to a reducing condition of unconsolidated material over a period of time. An indicator device including a reactive coating comprising a manganese oxide is also disclosed.
