Standard Grade quartz has moderate silicon dioxide (SiO₂) purity. They might contain some impurities such as iron, Aluminium, or other minerals, which slightly reduce their overall quality.

These are quartz lumps that are used primarily in industrial applications. They balance cost and performance, making them suitable for uses where absolute purity is not necessary but where the material’s hardness and chemical properties are still beneficial.

They are used in Ferro Alloy Industries, Glass Making, Ceramics, Abrasives and manyother industries.
