Talc is a Hydrated Magnesium Silicate with the chemical formula Mg3 Si4 O10 (OH)2.. It is a naturally occurring platy mineral. It can be white, grey, green, pale green & gray white in color. It has a Mohs hardness of 1, has a vitreous-pearly lustre, a white streak and has a density of 2.75.

Talc is valued for its extreme softness, smoothness, hydrophobicity, high lubricating and hiding power and for its ability to absorb oil and grease.

Talc is practically insoluble in water , weak acids and alkalis. It is neither explosive nor flammable. Although it has very little chemical reactivity, talc does have a marked affinity for certain organic chemicals, i.e. it is organophilic. Above 900°C, talc progressively loses its hydroxyl groups and above 1050°C, it re-crystallises into different forms of enstatite (anhydrous magnesium silicate). Talc’s melting point is at 1500°C.
