What mineral is harder than calcite but wont scratch glass?
Fluorite is a mineral that is harder than calcite but won't scratch glass. Calcite has a hardness of 3 on the Mohs scale, while fluorite has a hardness of 4. However, glass typically has a hardness of about 5.5, making it too hard for fluorite to scratch.
Can calcite scratch other minerals if so which one?
No.because calcite is softer then feldspar
What is harder glass or calcite?
Glass is generally harder than calcite. Calcite has a Mohs hardness of 3, while glass typically has a Mohs hardness of around 5.5. This means that glass is more resistant to scratching and abrasion compared to calcite.
What can Garnet scratch?
Garnet, a mineral with a hardness of 6.5-7.5 on the Mohs scale, can scratch materials with a hardness lower than itself, like glass, steel, and softer minerals such as calcite and fluorite.
What mineral will scratch glass but not a sreak plate?
A mineral that can scratch glass but not a streak plate is quartz. Quartz has a hardness of 7 on the Mohs scale, which allows it to scratch glass (which has a hardness of about 5.5) but is harder than the streak plate, typically made from porcelain, which has a hardness of around 6-7. Therefore, while quartz can leave scratches on glass, it will not produce a streak on a streak plate.

Can quartz be able to scratch calcite?
Qtz is a 7 on Mohs Hardness scale. So it can scratch itself or anything less on the scale. Just that simple.
What is the hardness of a mineral if it scratches a penny but will not scratch glass?
Between 3.5 and 5.5 on the Mohs scale of mineral hardness.
Will fake diamond cut glass?
Your answer depends on the composition of the 'fake diamond' and the composition of glass. Each mineral has a rating on the Mohs Scale of hardness. The harder mineral will scratch the softer mineral.

Is calcite a mineral and why?
By definition, a mineral must have a definite crystalline structure. Calcite has this. Glass is amorphous, meaning it does not have such a structure.
What can a copper penny scratch?
A copper penny can scratch materials with a Mohs hardness of 2.5 or lower, such as gypsum, talc, and some plastics. It will not scratch harder materials like glass, steel, or most ceramics.
Does the mineral serpentine scratch glass?
No. The hardness of serpentine is 3-4.5, whereas a hardness of at least 7 is needed to scratch glass.
What mineral will scratch glass but not a sreak plate?

Quartz has a hardness of 7 on the Mohs scale, which allows it to scratch glass (which has a hardness of about 5.5) but is harder than the streak plate, typically made from porcelain, which has a hardness of around 6-7. Therefore, while quartz can leave scratches on glass, it will not produce a streak on a streak plate.
Both calcite and quartz can be found as clear crystals what tests can be used to correctly identify them?
Quartz would scratch the calcite. Calcite would not scratch the quartz. Calcite will react with dilute hydrochloric acid. Quartz will not. Calcite will exhibit double refraction. Quartz will not. If the crystal forms are intact, quartz crystal may appear six sided with pyramidal terminations. If they are of equal size, the quartz will be heavier.
