Which of gypsums physical characteristics can be described as nonmetallic?
The nonmetallic physical characteristic of gypsum is its pearly or silky luster when it is broken into thin sheets or cleaved. This quality gives gypsum a unique appearance compared to metallic substances.
What mineral is nonmetallic and has a silky luster?
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.

Fluorite is a common mineral that forms in a variety of colors. Galena is a lead sulfide mineral with a metallic luster. Gypsum is a soft sulfate mineral commonly used in construction materials.
What type of mineral is colorless cannot be scratched by calcite has no shine and breaks apart in many ways?
The mineral you're describing is likely gypsum. Gypsum is colorless, has a hardness less than calcite (can't scratch it), has a dull or pearly luster (no shine), and typically breaks apart into small grains or fine powder.
How would you determine if a mineral was gypsum?
Gypsum is one of the softest of minerals. It is only 1.5 on the scale of hardness and can be cut with a knife. Gypsum's specific gravity is 2.2 and it weighs 135 pounds per square foot. It does not melt under a blowpipe and does not react to Hydrochloric acid. It often accompanies rock salt or halite and frequently contains Sulfur beds and may or may not be transparent.

Pyrite has a cubic crystal structure with metallic luster and a brassy yellow color, while gypsum has a monoclinic crystal structure with a pearly luster and colorless to white appearance. By examining the crystal structure under a microscope and observing the physical properties such as color and luster, one can distinguish between pyrite and gypsum crystals.
Is gypsum dull or shiny?
Gypsum is typically dull in appearance with a pearly to glassy luster. It can sometimes have a slight sheen or shine, but it is generally more matte in finish.
What are three types of mineral luster?
Metallic luster: minerals that have the appearance of polished metal, such as pyrite or galena. Vitreous luster: minerals that have a glassy appearance, like quartz or feldspar. Pearly luster: minerals that exhibit a soft, pearl-like sheen, such as talc or gypsum.
What does a mineral with a nonmetallic silky luster have?
A mineral with a nonmetallic silky luster is likely to be fibrous in structure, such as asbestos or satin spar gypsum. This type of luster is caused by the arrangement of fine parallel fibers that reflect light, creating a smooth and shiny appearance. Minerals with this luster are often valued for their unique texture and appearance.

Halite is typically clear or white in color, while gypsum is usually white or colorless with a pearly or glassy luster. Additionally, halite is soluble in water, while gypsum is only slightly soluble.
