The curing conditions affect the size of the droplets that in turn affect the final operating properties of the "smart window". Typically, the liquid mix of polymer and liquid crystals is placed between two layers of glass or plastic that include a thin layer of a transparent, conductive material followed by curing of the polymer, thereby ...
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 includes what are referred to as absorption centers.
Plate glass has been the most common glass used due to its low cost, but greater requirements for the optical properties and ballistic performance have generated the need for new materials. Chemical or thermal treatments can increase the strength of glasses, and the controlled crystallization of certain glass systems can produce transparent ...
A stained glass window is a window composed of pieces of colored glass, transparent, translucent or opaque, frequently portraying persons or scenes. Typically the glass in these windows is separated by lead glazing bars. Stained glass windows were popular in Victorian houses and some Wrightian houses, and are especially common in churches. [24]
One-way glass (4) used in a teleprompter. A one-way mirror is typically used as an apparently normal mirror in a brightly lit room, with a much darker room on the other side. People on the brightly lit side see their own reflection—it looks like a normal mirror. People on the dark side see through it—it looks like a transparent window. The ...
Electrochromic glass installed in buildings. Several electrochromic devices have been developed. Electrochromism is commonly used in the production of electrochromic windows or "smart glass", [3] [1] and more recently electrochromic displays on paper substrate as anti-counterfeiting systems integrated into packaging.

Pure metallic copper produces a very dark red, opaque glass, which is sometimes used as a substitute for gold in the production of ruby-colored glass. Metallic gold , in very small concentrations (around 0.001%, or 10 ppm), produces a rich ruby-colored glass ("Ruby Gold" or "Rubino Oro"), while lower concentrations produces a less intense red ...
These displays are also used in shop windows. The shopping windows show the product on the inside as well as show text or advertisements on the glass. [28] This type of showcase is becoming more popular as see-through screens are becoming cheaper and more available.
