Raw vermiculite is a natural mineral that has not yet undergone the expansion process. It is typically found in the form of small, flat, flaky particles with a shiny and metallic appearance. Raw vermiculite is hydrated, meaning it contains water molecules within its structure, which allows it to expand when heated.
This mineral is primarily used in gardening as a soil amendment, where it enhances water retention, aeration, and nutrient-holding capacity, making it beneficial for plant growth. It is also used in insulation and construction applications due to its thermal resistance and fireproof properties.
Raw vermiculite is non-toxic, odorless, and environmentally friendly, making it safe for use in various applications. Though it is not as lightweight as expanded vermiculite, it still offers excellent durability and stability for a variety of industrial and horticultural needs.
