To dull a shiny painted surface, you can lightly sand it with fine-grit sandpaper to create a matte finish. Alternatively, you can apply a matte or satin topcoat over the shiny surface to reduce its glossiness.
Slate is typically dull in appearance. It has a matte finish and does not have a shiny or reflective surface.
Brittle materials can exhibit both shiny and dull appearances. Whether a brittle material looks shiny or dull depends on its composition and surface characteristics. Some brittle materials might have a shiny appearance due to a smooth surface finish, while others may appear dull if they have a rough or textured surface.
Coal is generally dull in appearance, with a matte or non-reflective surface. It typically has a dark, black color and doesn't have a shiny or metallic lustre.
Chlorine, in its elemental form, is a diatomic gas at room temperature and pressure, so it does not have a surface. When chlorine is in a liquid or solid state, it appears as a yellow-greenish liquid or solid, and it does not have a shiny or dull surface.
Pumice is typically dull in appearance, as its surface is porous and contains many tiny air pockets. This texture gives it a frosted or matte finish rather than a shiny one.

A dull surface is a better absorber of infrared radiation heat compared to a shiny surface. The rough texture of a dull surface allows for more absorption of infrared radiation, while a shiny surface reflects much of the radiation.
You can dull shiny gold metal by using a fine-grit sandpaper to gently rub the surface until it becomes less shiny.

A dull surface would be a better absorber of light because its rough texture allows for greater light absorption due to increased surface area and multiple reflections within the material. Shiny surfaces reflect more light and are therefore poorer absorbers.
Hematite is typically shiny when it is polished or cut, giving it a metallic luster. However, in its natural form, hematite can appear dull or metallic depending on the surface finish and impurities present.
Pumice is typically dull in appearance, as its surface is porous and contains many tiny air pockets. This texture gives it a frosted or matte finish rather than a shiny one.
The term you're looking for is "luster." It refers to how light reflects off the surface of an object, giving it a shiny or dull appearance.
"Dull" refers to a matte or lackluster appearance, lacking shine or gloss. "Shiny" refers to having a gleaming or reflective surface, reflecting light and appearing glossy.
To dull shiny fake gold, you can lightly sand the surface with fine-grit sandpaper or apply a matte finish clear coat spray.
