Editing Mohs scale (section)

{{More citations needed|section|date=November 2022}}
Below is a table of more materials by Mohs scale. Some of them have a hardness between two of the Mohs scale reference minerals. Some solid substances that are not minerals have been assigned a hardness on the Mohs scale. Hardness may be difficult to determine, or may be misleading or meaningless, if a material is a mixture of two or more substances; for example, some sources have assigned a Mohs hardness of 6 or 7 to granite but it is a rock made of several minerals, each with its own Mohs hardness (e.g. topaz-rich granite contains: topaz — Mohs&nbsp;8, quartz — Mohs&nbsp;7, orthoclase — Mohs&nbsp;6, plagioclase — Mohs&nbsp;6–6.5, mica — Mohs&nbsp;2–4).
