What else can I help you with?
Would a steel file be able to scratch quartz?
yes
The two major types of minerals are what?
Two examples are quartz and mica. Minerals are also classified as metallic or non-metallic.
What is quartz fluorescence?
Fluorescence occurs when a substance has absorbed light and later emits that light. Quartz is a material that undergoes this process. Minerals and creatures can both exhibit fluorescence.
What causes the different colors of quartz?
Trace amounts of other minerals in the crystalline structure of the SiO4.
What is the value per pound of quartz?
This would depend upon a number of factors. Massive, or crystalline? Colorless, or colorful? Clear or opaque? Fractured or flawless? From the Swiss Alps, or from Arkansas? A buck a pound will get you good tumbling grade agate, but a well crystallized rose quartz specimen, or top grade rutilated quartz, or a nice Swiss smoky quartz crystal crowned with pink fluorite crystals... you can add two to four zeroes.
Which minerals will not scratch quartz?
Quartz has a Mohs hardness of 7, meaning minerals that are softer than quartz (Mohs < 7) will not be able to scratch it. Some examples include talc (Mohs 1), gypsum (Mohs 2), calcite (Mohs 3), and fluorite (Mohs 4).
What minerals can a steel knife scratch?
A steel knife can scratch minerals with a hardness lower than that of steel, such as gypsum, calcite, fluorite, and talc. Minerals like quartz, topaz, and corundum are harder than steel and cannot be easily scratched by a steel knife.
What two minerals are harder than calcite but softer than quartz?
Fluorite and apatite are two minerals that are harder than calcite but softer than quartz on the Mohs scale of mineral hardness. They have hardness values of 4 (fluorite) and 5 (apatite) respectively, compared to 3 for calcite and 7 for quartz.
What can scratch fluorite?
Fluorite is a relatively soft mineral with a Mohs hardness of 4, so it can be scratched by harder materials like quartz, topaz, and corundum. However, fluorite can scratch materials with a lower hardness, such as gypsum and calcite.
Which minerals on Mohs' hardness scale can be scratched by quartz?
Othoclase, apatite, fluorite, calcite, gypsum, and talc.
Which minerals would scratch fluorite?
Any mineral with a hardness greater than that of fluorite which is 4 on the Mohs scale of hardness. Examples include quartz, orthoclase, garnet, diamond, etc.
What are 8 examples of minerals?
Diamond, graphite, quartz, topaz, calcite, fluorite, dolomite, magnetite, hematite, pyrite...
Which mineral will scratch fluorite galena and pyroxene?
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Can calcite scratch other minerals if so which one?
No.because calcite is softer then feldspar
Which mineral is hard enough to scratch calcite but is not hard enough to scratch amphibole?
Quartz is hard enough to scratch calcite, as it has a higher hardness rating on the Mohs scale. However, quartz is not hard enough to scratch amphibole minerals, which are generally harder than calcite.
Which minerals can scratch apatite?
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
