Photomicrograph of epsomite "cave cotton" from a wall of a former limestone quarry cavern in Ohio

Summary

[edit]
Description
English: Photomicrograph of mineral fibers magnified 300 times found on a wall of a former limestone quarry cavern in Ohio, being used as a storage warehouse for painted and sculptural artwork.

Facility staff referred to the fibers as "cave cotton" due to the texture and appearance of the fibers. Atomic weight concentrations suggest that the mineral fiber contained a compound consisting of magnesium sulfate with formula MgSO4, referred to as epsomite.

This photograph was taken during a Health Hazard Evaluation, a NIOSH program by which employees, union officials, or employers can request an evaluation of possible health hazards at their workplace at no cost to them.
