Mineral wool

Mineral wool is a material made from natural minerals, like rocks. It is used in a variety of products like insulation, soundproofing, and filters. Mineral wool is made by melting rocks and spinning them into fibers or chunks, like cotton candy. They are then made into small particles that can be used to trap heat, sound, and particles. The minerals help the material last, so it can be used in many different places.
