No, they are two different minerals.
Talc is a very soft mineral, unlike quartz, and so is less likely to be abrasive.
Talc has a mineral structure that makes it very brittle all the way down to the molecular level - it only needs a touch to break and so it is considered a 'soft' mineral because it is so weak and breaks so easily.
Some non-metallic minerals include quartz, gypsum, feldspar, talc, and mica. These minerals are used in various industries such as construction, ceramics, and cosmetics.
Quartz, copper, fluorite, and talc are all minerals. There are over 4,900 known mineral species. Mineral species are controlled by the Earth's chemistry.
Orthoclase comes in as 6 on Mohs scale of mineral hardness:- Talc, Gypsum, Calcite, Fluorite, Apatite, Orthoclase, Quartz, Topaz, Corundum, Diamond;
Yes, talc is softer than quartz. Talc is assigned a hardness of 1 on the Mohs scale, while quartz has a hardness of 7. This means that quartz is significantly harder than talc.
Quartz- hardness 7 on Mohs Scale. (Calcite: 3, galena 2.5, talc 1)
Talc is a very soft mineral, unlike quartz, and so is less likely to be abrasive.
Quartz powder is dangerous to the respiratory system.
The mineral with a soapy feel is called talc. Talc has a greasy or soapy texture and is often used in powders and cosmetic products.
schist
Talc Diamond Quartz
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
quartz,talc,apatite,feldspar
Apatite is a mineral that can scratch feldspar but not quartz. This is because apatite has a higher hardness value than feldspar but a lower hardness value than quartz on the Mohs scale of mineral hardness.
pumice
No, smoky quartz and moonstone are different types of gemstones. Smoky quartz is a brown transparent quartz crystal, while moonstone is a variety of feldspar that typically exhibits a white to bluish sheen known as adularescence.
