Derived termsTerms derived from glass (noun)From Wiktionary under the GNU Free Documentation License. Glass generally refers to hard, brittle, transparent material, such as those used for windows, many bottles, or eyewear. Examples of such materials include, but are not limited to, soda-lime glass, borosilicate glass, acrylic glass, sugar glass, isinglass (Muscovy-glass), or aluminium oxynitride. In the technical sense, glass is an inorganic product of fusion which has been cooled through the glass transition to a rigid condition without crystallizing. Many glasses contain silica as their main component and glass former. In the scientific sense the term glass is often extended to all amorphous solids (and melts that easily form amorphous solids), including plastics, resins, or other silica-free amorphous solids. In addition, besides traditional melting techniques, any other means of preparation are considered, such as ion implantation, and the sol-gel method. However, and physics commonly includes only inorganic amorphous solids, while plastics and similar organics are covered by polymer science, biology and further scientific disciplines. Glass plays an essential role in science and industry. The optical and physical properties of glass make it suitable for applications such as flat glass, container glass, optics and optoelectronics material, laboratory equipment, thermal insulator (glass wool), reinforcement fiber (glass-reinforced plastic, glass fiber reinforced concrete), and art. The term glass developed in the late Roman Empire. It was in the Roman glassmaking center at Trier, Germany, that the late-Latin term glesum originated, probably from a Germanic word for a transparent, lustrous substance. From Wikipedia under the

We just got a ball python and I would like to get fingerprints off the outside of the "aquarium" glass. I know that I need to use vinegar or another natural cleaner for the interior, but can I use a commercial window cleaner (like Windex) for the outside glass? If not, what can I use as a streak free exterior glass cleaner? Asked by kanpope - Wed May 20 10:19:06 2009 - - 5 Answers - 0 Comments A. You can but you need to becarful it doesnt get inside the tank, and not to touch the outside of the tank when it is still wet and then touch the inside... also don't forget the the cleaner does tend to "mist" and some of it can get inside the tank, try putting it on a piece of cloth/paper towel and wipe the tank instead of spraying it right on... and it may help if you remove the tank first and put it in another bucket/get someone else to hold it, hope that helps! (i personally use warm water/mix with vinegar) Answered by aspinn2008 - Wed May 20 14:12:54 2009 What makes glass better than pastics for optical mirrors?
Q. I am new to astronomy, and I have been noticing how expensive large glass mirrors for reflector telescopes can get. I am just curious why a quality mirror can't just be cast or stamped out of say acrylic or polycarbonate or some other cheap plastic, then be polished and coated? Is there some property of plastic that makes it less suitable for a telescope mirror? Asked by YeahWellYouKnowHowItIs - Mon Dec 3 12:11:01 2007 - - 4 Answers - 0 Comments A. It's probably not possible to mold plastic with sufficient accuracy to use as a telescope mirror, because of the way molded plastic shrinks as it cools. That would require polishing and figuring, but plastic is too soft to polish with conventional methods. Thermoplastic resins tend to creep under load, making long-term stability an issue - store your mirror on edge and it could warp like a potato chip. This is not to say it couldn't be done - small precision lenses are routinely cast from resin. But the driving force behind developing those technologies is the market for millions of small camera lenses. The telescope market is a lot smaller, so the economic incentive to develop the technology is weak while the technical challenges are… [cont.] Answered by injanier - Mon Dec 3 12:34:31 2007 From Yahoo Answer Search: "Glass" |
