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 ...
Murano glass makers developed the exceptionally clear colourless glass cristallo, so called for its resemblance to natural crystal, which was extensively used for windows, mirrors, ships' lanterns, and lenses. [21] In the 13th, 14th, and 15th centuries, enamelling and gilding on glass vessels were perfected in Egypt and Syria. [44]
Feathering – creating feather-like patterns on a glass by dragging a metal tool across the surface of a newly applied wrap. Frit – crushed glass often melted onto other glass to produce patterns and color; Incalmo – the grafting or joining together, while still hot, of two separately blown glass [bubbles] to produce a single [bubble].

A one-way mirror, also called two-way mirror [1] (or one-way glass, half-silvered mirror, and semi-transparent mirror), is a reciprocal mirror that appears reflective from one side and transparent from the other. The perception of one-way transmission is achieved when one side of the mirror is brightly lit and the other side is dark.
A transparency meter, also called a clarity meter, is an instrument used to measure the transparency of an object. Transparency refers to the optical distinctness with which an object can be seen when viewed through plastic film/sheet, glass, etc. In the manufacture of sheeting/film, or glass the quantitative assessment of transparency is just ...
Bulletproof glass of a jeweler's window after a burglary attempt. The Mona Lisa behind bulletproof glass at the Louvre Museum. Bulletproof glass, ballistic glass, transparent armor, or bullet-resistant glass is a strong and optically transparent material that is particularly resistant to penetration by projectiles, although, like any other material, it is not completely impenetrable.

See-through graphics can be added to glass or other transparent panels to provide advertising, branding, architectural expression, one-way privacy and solar control. See-through graphics on the outside of a window See-through graphics: the view outside is unobstructed. Perforated self-adhesive window films are often used to create see-through ...
