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.
The mineral that fits this description is quartz. It has a hardness of 7 on the Mohs scale, which allows it to scratch glass, and it exhibits a vitreous luster. Quartz can occur in many different colors due to impurities in its crystal structure.
Yes, halite can scratch glass. Halite has a hardness of 2.5 on the Mohs scale, while glass has a hardness of about 5.5. This means that halite is softer than glass and can leave scratches on it.
A watch with sapphire glass has a transparent cover made from synthetic sapphire crystal. Sapphire glass is highly scratch-resistant, making it more durable and less prone to scratches than other types of watch crystals like mineral glass or acrylic. This results in a clearer and more scratch-free surface for the watch face.
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
Between 3.5 and 5.5 on the Mohs scale of mineral hardness.
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.
The mineral would have a hardness between 5.5 and 6.5 on the Mohs scale. It cannot scratch glass (hardness of about 5.5) but can scratch an iron nail (hardness of about 4). This places it in the range of minerals like orthoclase feldspar or apatite.
Diamond is the hardest mineral that can scratch a steel knife or window glass.
A mineral that will scratch with a window glass but not with a knife blade is a mineral with a hardness between 5.5 and 6.5 on the Mohs scale, such as orthoclase or peridot.
The unknown mineral is not a mineral, or the pieces being scratched or doing the scratching are not freshly fractured or cleaved surfaces.
The mineral that fits this description is quartz. It has a hardness of 7 on the Mohs scale, which allows it to scratch glass, and it exhibits a vitreous luster. Quartz can occur in many different colors due to impurities in its crystal structure.
The hardness would be between 4.5 and 5.5 on the Mohs scale. I actually think it would be 4.5, but to be safe, I would put between 4.5 and 5.5. Hope that helps!
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
The unknown mineral would have a hardness greater than 5.5 (the hardness of glass) but less than 7 (the hardness of quartz). Based on the Mohs Hardness Scale, the unknown mineral would likely have a hardness between 6 and 7.
I found a company that makes a few different products for glass and Plastic.They are Janvil. Their site is janvil.com . They have glass scratch removers for glass scratches and plastic polish
