Neumann, Florin. "Glass: Liquid or Solid – Science vs. an Urban Legend". Archived from the original on 9 April 2007 . Retrieved 8 April 2007. Today, glass is ordinary, on-the-kitchen-shelf stuff. But early in its history, glass was bling for kings. There are four modes available that affect image quality. Entertainment and Movie, look no different to my eyes, Sport switches you to a rather cooler colour temperature, while Vivid delivers a similar white point and more saturated colour-balance. Alas, there’s low-latency Game mode but you do get a couple of audio-centric modes – Music and Party – to play with, which do nothing to affect the picture but instead provide preset audio settings.

Then, another problem was discovered. Many of the glass colors did not stand up to year-in, year-out exposure to the direct Sodium carbonate (Na 2CO 3, "soda") is a common additive and acts to lower the glass-transition temperature. However, sodium silicate is water-soluble, so lime (CaO, calcium oxide, generally obtained from limestone), along with magnesium oxide (MgO), and aluminium oxide (Al 2O 3), are commonly added to improve chemical durability. Soda–lime glasses (Na 2O) + lime (CaO) + magnesia (MgO) + alumina (Al 2O 3) account for over 75% of manufactured glass, containing about 70 to 74% silica by weight. [68] [76] Soda–lime–silicate glass is transparent, easily formed, and most suitable for window glass and tableware. [77] However, it has a high thermal expansion and poor resistance to heat. [77] Soda–lime glass is typically used for windows, bottles, light bulbs, and jars. [75] Borosilicate A Pyrex borosilicate glass measuring cup Anderson, P.W. (1995). "Through the Glass Lightly".

There’s 215W of total amplification, too, ensuring that these deliver audio that’s far more forceful than most other TVs you’ll encounter, with vocals and speech delivery a real strength of the system. I fired up a John Legend concert recording on Sky Arts and both the piano and Legend’s voice came across in a convincing and pleasing manner.

The high-quality « glass skin» of the surface of our bottles and decanters, which comes from the tooling and the quality of the cast iron used, the great care with which our molds are prepared and maintained, and the precision of the multiple settings used during production. Schwartz, Mel (2002). Encyclopedia of Materials, Parts and Finishes (Seconded.). CRC Press. p.352. ISBN 978-1-4200-1716-8. In its default configuration, it sits on a central stand with the bottom edge of the set almost flush with the surface of your AV stand, but it can also be wall-mounted, and all the hardware to do that is included in the box. Bear in mind, however, that even without the sturdy stand attached to the rear, it’s still a bit of a lump, with the stand-less 43in weighing 14kg, the 55in on test 23kg and the 65in 28kg. I’d advise against mounting it on a plasterboard wall.Audio quality remains as good as ever, although that didn’t need improvement as badly as picture quality did. It isn’t as good, it must be said, as if you were to connect a decent dedicated soundbar, such as the Sonos Beam 2, but better than you’ll get with most TVs at around the price of Sky Glass.Indeed, Sky Glass plays host to a full 3.1.2 Dolby Atmos-compatible audio system. Four drivers are housed in the “soundbar” part of the TV – one centre speaker, one 120mm bass woofer and two stereo drivers – and there’s a pair of upward-firing Atmos speakers in the top corners of the TV set to deliver Atmos’ height effects.
