Quartz Lumps

Quartz is an industrial mineral used in the production of glass, cement, pottery, and filters. It provides a hard surface that does not degrade over time. It can be polished, crushed, or cut into diverse shapes for use in industries like construction (e.g., counter tops), engineering (e.g., bearings), and automotive (e.g., airbags); it is also incorporated into the manufacture of electrical insulators and electronic components, among myriad other uses.
