Stone wool production process

Mineral wool, also known as mineral fiber, mineral cotton, man-made mineral fibre (MMMF), and man-made vitreous fiber (MMVF), is a general name for fiber materials that are formed by spinning or drawing molten minerals (or "synthetic minerals" such as slag and ceramics). The nomenclature of these wool products is simply the parent/raw material name in prefix to wool. Wool from glass is glass wool, wool from rock is stone wool and so on. Specific mineral wool products are stone wool and slag wool. Europe also includes glass wool which, together with ceramic fiber, are completely man-made fibers. Applications of mineral wool include thermal insulation, filtration, soundproofing, and hydroponic growth medium.
