Abstract. Talc is a naturally occurring magnesium silicate mineral, widely used as a polymer filler. Its main differentiating features in this context are its softness (it is the softest mineral known) and lamellarity (platiness). Useful deposits are widespread and processed by conventional mining operations to produce filler grade material.
