The mineral you are describing is likely garnet, specifically a variety like almandine, which is dark red in color. Garnet has a hardness of about 7.5 to 8 on the Mohs scale, allowing it to scratch glass. It exhibits a non-metallic luster and typically shows a conchoidal fracture.
The Luster of a mineral is it's appearance in the light. Also there are two types of Luster, metallic and nonmetallic.
Luster is the light reflection a mineral has, which can be broken down into categories like metallic, silky, and dull. The luster dictates what type of mineral it is.
galena, pyrite, fluorite, perovskite, or halite cubes
I think its nonmetallic as it is glass
You can use hardness(Moh's Hardness Scale), luster, shape, and fracture to identify quartz.
The mineral that fits these descriptions is obsidian. Obsidian is a natural volcanic glass that can scratch glass, has a nonmetallic luster, typically exhibits conchoidal fracture, and is usually a dark color, such as black, dark green, or dark brown.
True. The luster of a mineral is described as either metallic or nonmetallic. Metallic luster reflects light like metal, while nonmetallic luster can vary from glassy to earthy in appearance.
If a mineral has a shiny luster, is it matallicIf a mineral has no shiny luster, is it nonmetallic?
Magnatite is the mineral that has a nonmatallic luster, is black, and can be scratched by a fingernail.
The mineral that fits this description is garnet. Garnet has a hardness of 6.5-7.5 on the Mohs scale, meaning it can scratch glass. It has a non-metallic luster, exhibits fracture rather than cleavage, and is commonly found in a dark red color.
The mineral you are referring to is likely magnetite. Magnetite is a black mineral with a nonmetallic luster, often appearing metallic or glassy. It is a common iron oxide mineral found in a variety of geological settings.
The Luster of a mineral is it's appearance in the light. Also there are two types of Luster, metallic and nonmetallic.
There is not enough information to go on. Many minerals fit this description, especially since there are several types of nonmetallic luster.
luster is used to determine if a mineral has metallic or nonmetallic shine. It also means the way a mineral reflects light
Depending on the variety, feldspars can range from adamantine to glassy in luster.
Luster. It describes how a mineral reflects light and can be used to distinguish different minerals based on their appearance. Minerals with a metallic luster appear shiny like metal, those with a submetallic luster are somewhat shiny, and those with a nonmetallic luster do not appear shiny.
The mineral that is nonmetallic and has a silky luster is serpentine. Serpentine is a group of minerals that are typically green in color and have a silky or waxy sheen on its surface. It is commonly found in metamorphic rocks.
