Is feldspar metalic?
no, feldspar is a mineral.
What is the luster of orthoclase?
Depending on the variety, feldspars can range from adamantine to glassy in luster.
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 mineral has a non-metallic luster?
One example of a mineral with a non-metallic luster is quartz. Quartz typically exhibits a vitreous (glass-like) luster, which can range from transparent to translucent. Other minerals with non-metallic luster include calcite and feldspar, each displaying distinct appearances in terms of shine and light reflection. Non-metallic luster is characterized by a lack of metallic sheen, often appearing dull, pearly, or silky.
Does granite have luster?
Granite is a rock and does not possess one specific luster but a composition of lusters, mostly glassy. It possesses a coarse grained crystalline texture.
Is the luster of feldspar considered metallic?
The luster of feldspar is considered vitreous.

What does feldspar look like?
Feldspar is a common mineral that can appear in various colors such as white, pink, grey, or green. It typically forms as rectangular prismatic crystals or as granular masses. In its most common form, feldspar typically has a glassy or pearly luster and is often found in igneous and metamorphic rocks.

Is feldspar shiny or dull?
i think that it is dull
What is the luster of sandstone?
The luster of sandstone is typically dull to matte due to its composition of mostly quartz and feldspar minerals. These minerals have a hardness lower than that of glass, which contributes to the lack of a reflective or shiny surface. The presence of clay and other impurities can also affect the luster, making it appear more earthy or muted.
What is the luster of arkose on the mohs scale for hardness?
Arkose typically has a luster ranging from dull to earthy due to its composition of quartz, feldspar, and other minerals. On the Mohs scale of hardness, arkose has a hardness of around 6-7, depending on the specific mineral content and composition.
What are whitish-gray stones with a nonmetallic luster that leave a colorless streak?
Whitish-gray stones with a nonmetallic luster that leave a colorless streak are likely to be varieties of minerals such as quartz or feldspar. These minerals often exhibit a light color and can be found in many geological environments. Their nonmetallic luster and ability to leave a colorless streak are characteristic features used to identify them in mineralogy. Further examination, including hardness and crystal structure, would help in precise identification.
What is the fracture of feldspar?
Feldspar's fracture is brittle
