Topaz is #8 on the Mohs scale of mineral hardness.
Topaz is the mineral that defines 7 on the Mohs scale.
Topaz is number 8 on the Mohs scale.
Yes Topaz is a mineral. On the Mohs. Scale it is 8 for its hardness.
Topaz ranks 8 on the Mohs scale for hardness.
Aquamarine is between 7(Quartz) and 8(Topaz) on MOHs scale of hardness. But, Aquamarine is closer to 8(Topaz) than 7(Quartz). :-)
no,calcite is ranked number 3 on the mohs scale of hardness. topaz is ranked number 8 on mohs scale of hardness. 10 is the hardest(diamond) 1 is the softest(talc) look it up!
No. Gypsum has a hardness on the Mohs scale of 2. Topaz has a hardness on the Mohs scale of 8. This means that topaz ranks much harder than gypsum and that gypsum cannot scratch topaz. Please do not refer to these numbers as absolute hardness. This does not mean that topaz is 4 times as hard as gypsum since they are ranked 8 and 2. The Mohs scale only designates a hardness scale of 1 through 10 so that geologists and mineralogists in the field have a quick way of determining a mineral's identity or eliminating possible options of what the mineral may be.
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
topaz has a hardness of 8 on the mohs hardness scale, quartz has a hardness of 7. topaz will be able to scratch quartz, but quartz can never scratch topaz.
By comparing its ability to scratch or be scratched by minerals with a known hardness on the Mohs hardness scale. For instance, if a mineral can scratch quartz (Mohs-7), but is scratched by topaz (Mohs-8), its hardness is somewhere between 7-8 on the Mohs scale.
A topaz has a hardness factor of 8 on the Mohs scale, whereas a diamond is a 10.
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
Fayalite has a hardness of 6.5-7 on the Mohs scale. Therefore it scratches orthoclase (hardness 6), but not topaz (hardness 8).
Topaz (8), corundum (9), and diamond (10).
The Mohs scale. # Talc # Gypsum # Calcite # Fluorite # Apatite # Feldspar # Quartz # Topaz # Corundum # Diamond The Mohs scale, however, is an purely ordinal scale. For example, corundum (9) is twice as hard as topaz (8), but diamond (10) is almost four times as hard as corundum. Check the related link for more info.
Yes..in a high definition the Fayalite can be able to scratch the Orthoclase but not the topaz. If you look on the Mohs scale, the Orthoclase is not harder than the Topaz. So, in clear words, yes!!
No. Hardness is measured on the Mohs Scale, named after German Friedrich Mohs. On this scale Talc (the softest) measures 1, while Diamond (the hardest) measures 10. Glass has a Mohs' scale hardness of around 5.5, so anything above that will have the ability to scratch glass. For example, quartz (Mohs 7), hardened steel (Mohs 8), corundum (rubies and sapphires, Mohs 9),or diamond (Mohs 10). The Mohs scale is purely an ordinal scale, expressing relative hardness in a simplistic way. Carborundum (Mohs 9) is twice as hard as Topaz (Mohs 8), but diamond (Mohs 10) is four times harder than arborundum.
On the Mohs relative hardness scale, the top three from the hardest down are diamond, corundum, topaz.
it is number 10 on the mohs scale
what is platnum on the mohs scale
Tantalum is 6.5 on the Mohs scale,
Mohs measures relative hardness (quartz is harder than orthoclase; topaz is harder than quartz), but it doesn't accurately tell HOW MUCH harder something is than something else. There is another scale, called the Rockwell, which does this.
2.5-3 on the Mohs scale.
Fluorite is 4 on the Mohs scale.
No, gypsum cannot scratch topaz. Minerals with a higher number on the Moh's Hardness Scale can scratch minerals that are lower-numbered, but lower numbers can't scratch higher numbers. A mineral would have to have a number higher than an 8 on the Moh's hardness scale in order to scratch topaz.
