obsidian
Smooth and shiny with no visible grain.
It goes shiny and smooth.
use conditioner, it's gonna make your hairs shiny and smooth.
A dull grainy looking rock is more likely to let water pass through it compared to a smooth shiny rock. The rough texture of the grainy rock provides more surface area for water to seep into and flow through, while the smooth rock may have a more compact structure that prevents easy passage of water.
Marble. The crystals are ofcalcite (calcium carbonate). It's only smooth when polished, but it takes a high polish.
i think that igneous and metamorphic rocks uses luster because maybe they have it in them
The Dull and grainy looking rock is more likely to let water pass though
A rock that is heavy and silky could potentially be anthracite, which is a type of coal known for its high density and smooth, shiny appearance. Another possibility could be serpentine, a metamorphic rock that can have a slick, smooth surface due to its high content of the mineral serpentine.
It isn't.... take water for example it isn't "smooth" or "shiny" but has reflective properties
Shiny and smooth.
mica
Gneiss is a coarse-grained metamorphic rock that can have a range of textures and appearances. While some gneisses can have a shiny appearance due to the presence of minerals like mica, they are generally not smooth like polished stones but rather have a rough or bumpy texture due to their mineral composition and formation process.
