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]
A classic 20-facet Soviet table-glass, produced in the city of Gus-Khrustalny since 1943. Tumblers are flat-bottomed drinking glasses. Collins glass, for a tall mixed drink. [5] Dizzy cocktail glass, a glass with a wide, shallow bowl, comparable to a normal cocktail glass but without the stem; Faceted glass or granyonyi stakan
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.
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]. [4]
Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.
“If you’re worrying about it at 3 a.m., thinking you’ll never be able to do X, Y, Z, put that plan together and then test it. In your head space, nothing can really get done.”
Cristallo is a glass that is totally clear (like rock crystal), without the slight yellow or greenish color originating from iron oxide impurities. This effect is achieved through small additions of manganese oxide. [1] Cristallo often has a low lime content, which makes it prone to glass corrosion (otherwise known as glass disease).
