Talcron products are intended for use as a general purpose talc filler in caulking compounds, automotive sound deadeners, auto-body putty, anti-caking agents in fertilizer, construction chalk line powder, and other miscellaneous end uses where color is of secondary importance and an economical source of talc is desired. There are no detectable quantities of asbestiform minerals.

When used in ceramics, tests should be done to be sure that the iron content does not darken the mix more than can be tolerated.
