Talc: Talc is a phyllosilicate mineral that cleaves into thin sheets. These sheets are held together only by van der Waals bonds, which allows them to easily slip past one another. This characteristic is responsible for talc's extreme softness, its greasy to soapy feel, and its value as a high-temperature lubricant. What is Talc?
