Vermiculite is a naturally occurring mineral that takes the form of glossy flakes, varying in color from dark gray to sandy brown. It is a hydrous phyllosilicate mineral that undergoes significant expansion when heated, and exfoliation occurs when the mineral is heated sufficiently. Vermiculite is used in various industries, including the building and car industries, as well as in packaging. In horticulture, vermiculite is sold as lightweight, absorbent brown-gold flakes and is used to improve soil quality or give seedlings a helping hand to root more quickly. Vermiculite can absorb three or four times its weight in water and also attracts various plant nutrients such as potassium, magnesium, and calcium, making it useful for propagation and for potting up plants that do best in moist compost. Vermiculite is also used as an anti-caking agent in fertilizers. However, it is important to note that some vermiculite products may contain asbestos, which can cause health problems if inhaled. Therefore, it is recommended to identify insulation that is made from vermiculite and take necessary precautions to protect oneself and family from exposure to asbestos.
