Asbestos (/ s b s t s, z-,-t s /) is a naturally occurring fibrous silicate mineral.There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. It aligns the physical, mental, emotional, and spiritual bodies with the etheric body to ensure optimal health. Quartz is a hard, crystalline mineral composed of silica (silicon dioxide).The atoms are linked in a continuous framework of SiO 4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.. Quartz exists in two forms, the normal Aperture is a hole, gap, or slit and any other small opening. This compound is banned because of its toxic properties toward a human. What is Hornblende?
