Materials that allow the transmission of light waves through them are called optically transparent. Chemically pure (undoped) window glass and clean river or spring water are prime examples of this. Materials that do not allow the transmission of any light wave frequencies are called opaque. Such substances may have a chemical composition which ...

The materials which can be made translucent include gossamer, silk, rayon or nylon. Sheer fabric comes in a wide variety of colors, but for curtains, white and shades of white, such as cream, winter white, eggshell, and ivory are popular. In some cases, sheer fabric is embellished with embroidered patterns or designs.
The arc-tube seals of high pressure sodium vapor lamps are made from niobium, sometimes alloyed with 1% of zirconium; niobium has a very similar coefficient of thermal expansion, matching the sintered alumina arc tube ceramic, a translucent material which resists chemical attack or reduction by the hot liquid sodium and sodium vapour contained ...
Transparent armor is a material or system of materials designed to be optically transparent, yet protect from fragmentation or ballistic impacts. The primary requirement for a transparent armor system is to not only defeat the designated threat but also provide a multi-hit capability with minimized distortion of surrounding areas.
It was around 1.6k all in materials, but counting all the days of free labor and buying the mates beers, za's and uppers - maybe near the line.. #47 The biggest life changing thing we ever ...
Translucent concrete (also: light-transmitting concrete) is a concrete based building material with light-transmissive properties due to embedded light optical elements — usually optical fibers. Light is conducted through the stone from one end to the other. Therefore, the fibers have to go through the whole object.
