Talc
The softest mineral in the world, functional and environmentally friendly.
What is Talc?
Talc is the softest mineral in the world and is known for its functional and environmentally friendly properties. It is smooth, sheet-like, water-repellent, and chemically inert, meaning it doesn't react easily with other substances. No two pieces of talc are exactly alike, which makes each one unique.
You can find talc in many everyday products, such as magazines we read, plastics used in cars and household appliances, as well as in paints and coatings. These are just a few examples of the many products that are improved by talc.
Chemically, talc is a magnesium silicate hydrate with the formula Mg3 Si4 O10 (OH)2. Its basic crystal structure consists of layers of magnesium-oxygen octahedra sandwiched between layers of silicate. The main surface of talc flakes contains no hydroxyl groups or active ions, which is why it is both water-repellent and chemically inert.
