If you look around from where you stand, you can probably see several pieces of glass: a window, reading glasses, mirror, computer screen, a lightbulb, maybe even a vase. Glass, with its design, is a vast and innovative material that has countless applications. It is an necessary component of numerous products that we use every day, most often without noticing. Few mass-produced substances add as much to modern living as glass does. It is clear that modern life would not be made possible without the manufacturing of glass.
The curious physical, optical and aesthetic properties of glass have always fascinated man. Even the most advanced 21st Century human is amazed and perplexed by this solid, which can be described as a rigid uncrystallised liquid. The product and the process used to manufacture glass seem to flout alchemy, for glass is nothing but coarse sand and soda ash transformed into smooth clear forms.
Forms of glass have existed for millions of years. Whenever natural events entailing very high temperatures: lightning strikes, volcanic activity or the collision of meteorites, causes the fusing of certain rocks, melt and then cool rapidly - it makes glass. Fossil evidence shows that in the Stone Age, humans used this natural glass to make tools (spearheads and cutting instruments) as far back as 9,000 years ago. Obsidian, shiny black glass formed when lava cools quickly, was widely used by ancient people for this purpose.
Everyday glass is made from natural and abundant raw materials (sand 74%, soda ash 14% and limestone 12%) that are melted at very high temperatures to form a new material. At high temperatures glass is structurally similar to liquids, however at normal temperatures it behaves like a solid. As a result, ...

...s for conducting electricity and to reflect heat were also developed. And products marrying these developments were created to help make life more comfortable, convenient, safer and beautiful. The world can now benefit because technology has made glass a flexible, easy-to-use miracle.
During the late 1960's, glass manufacturers established collection centres where people could return empty jars, bottles and other types of glass. One of the many advantages that was realised with this wave of recycling is that the material is theoretically infinitely recyclable which will not deteriorate with use and age and has no loss of quality. in fact, recycling glass employs less energy than when it is manufactured from sand, lime and soda. However, glass can only really be considered a renewable material when in a recycled or re-used form, not when it is initially manufactured.
Technology is evolving and growing as fast as Moore’s Law has predicted. Every year a new device or process is introduced and legacy devices becomes obsolete. Twenty years ago, no one ever thought that foldable and paper screens would be even feasible. Today, although it isn’t a consumer product yet, foldable and paper screens are a reality. Home automation, a more prominent example of new technologies that were science fiction years ago are now becoming an integral part of life. As technology and its foothold in today’s world grows, its effects on humanity begin to show and much more prominently than ever. In his essay, O.k. Glass, Gary Shteyngart shows the effects of technology in general and on a personal note. Through the use of literary
Glass transition is not the same as melting. Melting (or freezing, or boiling or condensation) undergoes a change in heat capacity and a latent heat is involved or in another term, melting is a first order transition that only occurs in crystalline polymers. However, for glass transition, it is a second-order transition that only occurs in the amorphous polymers and does not involve latent heat since amorphous polymers have a relatively weak intermolecular forces that bond them together and can be broken once heat is applied whereas crystalline polymers have a strong primary (cross-linking) covalent bonds. Glass transition temperature and melting temperature can occur in the same process because in a semi-crystalline polymers, both amorphous and crystalline regions exist where the amorphous polymers undergo only the glass transition and the crystalline polymers undergo only
GLASS written by ellen hopkins intermenes the real life struggles that teenagers face everyday, from love to drugs to destructive relationships. Ellen really hits home showing the life of a once 4.0 honors student Kristina; whose life easily got turned upside down from one toxic summer at her fathers that will show the darkest side possible of life. An estimated 12 percent of children in the United States live with a parent who is dependent on or abuses alcohol or other drugs. Based on data from 2002 through 2007, it was to be reported that 8.3 million children under the age of 18 lived with at least one substance-dependent or substance-abusing parent according to Substance Abuse and Mental Health Services Administration (Paragraph 4). The bond between a child and their parents is so pure yet

Rex Walls While growing up in life, children need their parents to teach them and lead them on the path to a successful future. In the Glass Castle Rex Walls, Jeannette’s father, neglects to take care of his duties as a father figure in Jeannette’s life. In the same way, he teaches her to be strong and independent at a very young age. As we read through the story, we see the special relationship that Jeannette shares with her father. Even though he, in many instances, failed to protect his children, refused to take responsibility for them, and even stole from them, Jeannette still loved him until his death for two reasons: one, for his ability to make her feel special, and two, because he is a never-ending source of inspiration.
Jeannette Walls did not have your average childhood. She grew up poor and neglected and faced many hardships as a child. Many of the problems she faced as a child were caused by her parents. Her mother, Rose Mary, clearly suffers from narcissistic personality disorder which affects not only Jeannette but the entire family. It is evident throughout the entire story that Rose Mary clearly puts her wants and needs ahead of her childrens showing her narcissistic tendencies.

You know that one book that you end up seeing everywhere. The one that everyone love and begs for you to read, just so that they have someone to talk about it with. The one that every book youtuber has reviewed. Well, Throne of Glass by Sarah J. Maas, is that book. Throne of Glass is aimed for audiences 17 and up.
Time has taught humanity many things. From stone walls to wooden tree houses to glass homes. As far as creation is concerned, glass was and is necessary. Though some cities differ in the use of glass materials they are alike with some architectural aspects. From manufacturing companies for cars to your grandmother’s fine china; we’re talking about glass use of interior design. Some materials of glass are more expensive than others due to the use and weight of glass. With glass windows to windows to cars, glass has become a major factor in society without a doubt. Time has given us many things; stained glass for instance was even use as a symbol for religious purposes. Today we will discover three topics on how of an importance glass is in interior
Fire. Neglect. Sexual Molestation. No one child should have to face what Jeannette Walls had to endure as a young child. However, Walls clearly shows this chaos and the dysfunctional issues that she had to overcome while she was growing up. Within her memoir, The Glass Castle, Walls incorporates little things that were important in her life in order to help the reader understand her story even more. These little things amount to important symbolisms and metaphors that help to give the story a deeper meaning and to truly understand Jeannette and her family’s life.
In September 1959 DiVita asked 2nd Lt. Richard Sturzebecher if he knew of a way to produce a strong glass fiber that would be capable of carrying a light signal. Sturzebecher had melted 3 triaxil glass systems together for his senior exam at Alfred University. In his exam, Sturzebecher had used SiO2, a glass powder produced by Corning. Whenever he had tried to look at the substance through a microscope he would end up with headache. Sturzebecher realized that these headaches came from the high amounts of white light produced from the microscopes light that was reflected through the eyepiece via the SiO2. SiO2 would be an ideal substance for transmitting strong light signals if it could be developed into a strong fibre.

Generally when some one writes a play they try to elude some deeper meaning or insight in it. Meaning about one's self or about life as a whole. Tennessee Williams' "The Glass Menagerie" is no exception the insight Williams portrays is about himself. Being that this play establishes itself as a memory play Williams is giving the audience a look at his own life, but being that the play is memory some things are exaggerated and these exaggerations describe the extremity of how Williams felt during these moments (Kirszner and Mandell 1807). The play centers itself on three characters. These three characters are: Amanda Wingfield, the mother and a women of a great confusing nature; Laura Wingfield, one who is slightly crippled and lets that make her extremely self conscious; and Tom Wingfield, one who feels trapped and is looking for a way out (Kirszner and Mandell 1805-06). Williams' characters are all lost in a dreamy state of illusion or escape wishing for something that they don't have. As the play goes from start to finish, as the events take place and the play progresses each of the characters undergoes a process, a change, or better yet a transition. At the beginning of each characters role they are all in a state of mind which causes them to slightly confuse what is real with what is not, by failing to realize or refusing to see what is illusioned truth and what is whole truth. By the end of the play each character moves out of this state of dreamy not quite factual reality, and is better able to see and face facts as to the way things are, however not all the characters have completely emerged from illusion, but all have moved from the world of dreams to truth by a whole or lesser degree.
The air in between the layers of glass should be thick and dense, so that it can save energy. One of the most common airs used in-between glass is argon. When argon is used heat loss is reduced. You could also use carbon dioxide or sulfur hexa-fluoride between glass.
