Will the mineral topaz scratch quartz or will quartz scratch topaz Why?
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.
What minerals can scratch emeralds?
Emeralds have a hardness of around 7.5-8 on the Mohs scale, so minerals with a higher hardness like corundum (9) and diamond (10) can scratch emeralds. Minerals with a lower hardness, such as quartz (7) and feldspar (6), would not be able to scratch an emerald.
Can corundum scratch topaz?
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
Is the mohs hardness scale is it relative to a scale?
Mohs scale is a relative scale that defines the hardness of a mineral as its ability to produce a scratch on the surface of a reference mineral. The number for hardness assigned to the tested mineral is the number given to the hardest material that the mineral can scratch. The reference materials are 1) Talc 2) Gypsum 3) Calcite 4) Fluorite 5) Apatite 6) Orthoclase 7) Quartz 8) Topaz 9) Korundum 10) Diamond These materials can be tested more quantitatively for their hardness by standardized tests on how resistent they are against scratching. The mohs scale is thus more of a handy tool when one is out in the countryside and wants to have a rapid test if one found a quartz or a calcite.
What is the Mohs Hardness Scale of the Blue Sapphire?
1 to 10. but above 5 to 8 is amazing stone.
If a material has a hardness of 8 can it not be scratched by a material with a hardness of 7?
Yes, a material with a hardness of 8 can scratch a material with a hardness of 7, but not the other way around. Hardness is a measure of a material's resistance to scratching, so a material with a higher hardness value can scratch a material with a lower hardness value.
Will the mineral topaz scratch quartz or will quartz scratch topaz Why?
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.
What kind of mineral can scratch quartz but not diamond?
According to the Mohs scale of hardness, Diamond has a hardness of 10 and Quartz has a hardness of 7. Any mineral with a hardness greater than 7 can scratch quartz and diamond can scratch any mineral with a hardness less than 10. Corundum (hardness of 9) and Topaz (hardness of 8) are two examples of minerals that can scratch quartz but not diamond.
What minerals can scratch emeralds?
Emeralds have a hardness of around 7.5-8 on the Mohs scale, so minerals with a higher hardness like corundum (9) and diamond (10) can scratch emeralds. Minerals with a lower hardness, such as quartz (7) and feldspar (6), would not be able to scratch an emerald.
Can corundum scratch topaz?
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
What minerals have a hardness of 7 on the mohs scale?
Minerals that have a hardness of 7 on the Mohs scale include quartz, beryl (which includes emerald and aquamarine), and garnet. These minerals are relatively hard and can scratch materials with a lower hardness rating.
Could corundum scratch topaz?
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
5 why is Gypsum is a 2 on Mohs hardness scale while topaz is an 8 Can gypsum scratch topaz?
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.
What mineral can scratch glass and be scratched by topaz?
Quartz is the mineral that can scratch glass and be scratched by topaz. Quartz ranks 7 on the Mohs scale of mineral hardness, scratching glass which ranks around 5.5. Topaz, ranking 8 on the Mohs scale, can scratch quartz but not glass.
Glass has a hardness of about 5.5 what minerals would scratch the glass?
There are many minerals with hardness above 5.5 but the standard ones are feldspar,quartz, topaz, corundum and diamond.
How is the hardness range for a mineral determined?
The answer is quite complicated in fact I don't know the exact answer. What I really know is that a geologist will probably know the exact answer. Geologists study rocks and rocks have lots of minerals. You can search the answer as well by looking at geologist websites. If it doesn't work then I hope someone else can edit this answer.
Does gypsum scratch flourite?
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.
