In other words, a translucent material is made up of components with different indices of refraction. A transparent material is made up of components with a uniform index of refraction. [1] Transparent materials appear clear, with the overall appearance of one color, or any combination leading up to a brilliant spectrum of every color.
Pure cellulose fiber is translucent, and it is the air trapped between fibers that makes paper opaque and look white. [3] If the fibers are refined and beaten until all the air is taken out, then the resulting sheet will be translucent. Translucent papers are dense and contain up to 10% moisture at 50% humidity.
A highlighter, also called a fluorescent pen, is a type of writing device used to bring attention to sections of text by marking them with a vivid, translucent colour. [1] A typical highlighter is fluorescent yellow, with the color coming from pyranine. [2] Different compounds, such as rhodamines (Rhodamine 6GD, Rhodamine B) are used for other ...
Vellum is prepared animal skin or membrane, typically used as writing material. It is often distinguished from parchment, either by being made from calfskin (rather than the skin of other animals), [1] or simply by being of a higher quality. [2] Vellum is prepared for writing and printing on single pages, scrolls, and codices (books).

[2] It was usually used with carbon paper for typing duplicates in a typewriter , for permanent records where low bulk was important, or for airmail correspondence. [ 3 ]
A writing material, also called a writing medium, is a surface that can be written on with suitable instruments, or used for symbolic or representational drawings. Building materials on which writings or drawings are produced are not included.
However, there is also a specific, quantitative definition of "opacity", used in astronomy, plasma physics, and other fields, given here. In this use, "opacity" is another term for the mass attenuation coefficient (or, depending on context, mass absorption coefficient , the difference is described here ) κ ν {\displaystyle \kappa _{\nu }} at ...
Paper lanterns are likely derived from earlier lanterns that used other types of translucent material like silk, horn, or animal skin.The material covering was used to prevent the flame in the lantern from being extinguished by wind, while still retaining its use as a light source.
