Vermiculite is an aluminum-iron hydrate silicate like mica. It can be used for many industrial applications and has been used as insulation. Being a mom is a full time job except no pay check no sick days shirt. Some sources of vermiculite deposits have been found to be contaminated with small amounts of asbestos. A vermiculite mine operated by W. R. Grace and Company in Libby, Montana makes it dangerous for workers and community residents to exploit asbestos-contaminated vermiculite, typically richterite, winchite, actinolite or tremolite.  Asbestos-containing vermiculite from Libby mine has been used as insulation in residential and commercial buildings throughout Canada and the United States. The filled Vermiculite of W. R. Grace and Company is marketed under the name Zonolite but is also used in spray products such as Monokote. In 1999, EPA began a Libby cleanup effort and now the area is a Superfund cleanup area.  EPA has determined that harmful asbestos is released from the mine as well as through other activities that disrupt the region’s land. Tan (talc) can sometimes be contaminated with asbestos due to the proximity of asbestos ore (usually tremolite) in underground mines.  In 1973, US federal law required all non-asbestos-soluble products,  and today has strict quality control in the manufacture of cosmetic-soluble, soluble products (wallet For example, talcum powder from industrial grade (often used in friction products) has largely eliminated this problem for consumers.
