An opaque substance transmits no light, and therefore reflects, scatters, or absorbs all of it. Other categories of visual appearance, related to the perception of regular or diffuse reflection and transmission of light, have been organized under the concept of cesia in an order system with three variables, including opacity, transparency and ...
Materials that do not transmit light are called opaque. Many such substances have a chemical composition which includes what are referred to as absorption centers. Many substances are selective in their absorption of white light frequencies. They absorb certain portions of the visible spectrum while reflecting others. The frequencies of the ...
Jadeite, “Jadite” or “Jade-ite” is a type of jade green opaque milk glass, originally popular in the United States in the early to mid-20th century.A blue milk glass called “Delphite” (Delfite, Jeannette Glass) and "Azur-ite" (Anchor Hocking) was also produced for several years.

Tablet with opaque blister packaging. An opacifier is a substance added to a material in order to make the ensuing system opaque. An example of a chemical opacifier is titanium dioxide (TiO 2), which is used as an opacifier in paints, in paper, and in plastics. It has very high refraction index (rutile modification 2.7 and anatase modification ...
