Talc is hydrated magnesium silicate. It generally occurs in two morphologies, either macro- or microcrystalline. Talc can have slightly differing compositions subject to the associated minerals in the orebody, but all talcs exhibit to a lesser or greater extent the following unique features: softness, hydrophobicity, platyness and organophily. These properties can be further enhanced by careful and sometimes propriety processing and bring a number of specific benefits to a wide range of industries including paper, paints, plastics, ceramics, rubber, personal care and roofing.

In low-temperature earthenware, talcs improve plasticity in the ram process. They contribute to a good glaze-body fit and, for very fast firing cycles, they reduce cool-down cracks.
For low-temperature porcelain, low iron content grades improve vitrification, allowing shorter firing cycles and improved mechanical resistance.
Combined with feldspar to form a eutectic-flux,  talcs reduce firing temperatures and cycles. They also stabilize firing shrinkage. Talcs control thermal and moisture expansion, thereby improving glaze-body fit and reducing delayed crazing.

In paper industry, irreversibly adsorbs organics, preventing their agglomeration, regardless of changes in process temperature or pH. ,improves plant productivity, reducing specific energy demand and plant discharge. ,ignificantly improves paper machine and printing press runnability while improving paper quality. reduces stickies deposits in recycled paper production and keeps the process 'clean', resulting in superior paper quality. enables the amount of chemicals to be reduced on paper machines, thus improving cost-effectiveness.
