What minerals would scratch fluorite - talc quartz or calcite?
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.
Can quartz be scratched by a penny?
No. According to Mohs Hardness Scale, Quartz has a hardness of 7 while copper has a hardness of about 3. The higher number indicates a greater hardness.
What is the hardness of a ruby on the Moh's hardness scale?
A ruby is a mineral corundum. The Mohs hardness scale lists the following from softer to harder: Talc - 1 Gypsum - 2 Calcite - 3 Fluorite - 4 Apatite - 5 Feldspar - 6 Quartz - 7 Topaz - 8 Corundum (which includes the ruby) - 9 Diamond - 10 Ruby has a Mohs hardness of 9.
What is the hardness of opal?
Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike crystalline forms of silica, which are classed as minerals Opal is a hydrated amorphous form of silica; its water content may range from 3 to 21% by weight, but is usually between 6 and 10%.

What will scratch calcite?
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
What is the mohs hardness of scale of limestone?

Can you scratch a copper coin with a knife blade?
Yes because a copper coin (being made of copper which is a 3 on the Mohs scale of hardness), is not as hard as a knife blade (which is a 5.5 on the Mohs scale of hardness).
Which object can scratch calcite but not apatite?
On the Mohs mineral hardness scale, calcite is about a 3, and apatite is about a 5. So, whatever is at a hardness of 4 will scratch a 3 but not a 5. That mineral is fluorite.
What is the hardness of dolomite on the MOHS hardness scale?
Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.
