What is a Glass contanier?
A glass container is anything made of glass that is used to contain or store something. For instance, a jar or a bottle made of glass is a glass container.
What are properties of glass that are useful?
glass is highly brittle. it is used for insulation and decoration.
Element used for cement and glass?
The key element in cement and glass is silicon.
What is the difference between 'glass' and 'a glass'?
A glass is made of glass.A glass is a single object used for drinking liquid. The article "a" before glass tells us we are talking about a single object.Whereas glass (no 'a') is a material that is used to make different objects eg a mirror, a window, a vessel to hold water etc
What advantage do glass and plastic containers have over aluminum cans?
An advantage that glass and plastic containers have over aluminum cans is that glass and plastic containers, after used, can be washed, disinfected, and used again. Also now both glass and plastic can also be recycled.
What type of glass are mainly used on cars?
Laminated glass, used mainly for windshields and tempered glass for the rear and side windows.
What materials are used to make old cars?
if you mean materials used to make cars say in 1918: alot of wood for interiors, stamped metal for bodies, and glass for lighting and windshields. in say 1970,s alot of stamped metal,more vinyl for interiors, molded plastics,and laminated plastics wil tempered glass for windshields. today, 2009, alot of molded plastics inside and out, alot of very thin steel, laminated windshields, tupperware bumpers ,etc, and aluminium.
What is laminated glass usually used for?
Laminated glass is used in home construction and has many different applications. It can be used for safety and security in windows as glass is normally very easily broken but once laminated it becomes much tougher.
What are the types of glass they use in cars?
Side and rear uses "tempered" glass. Tempered glass is used because it breaks into small pieces and does not create long, sharp shards which can stab you. Windshields are made of "Laminated" glass, meaning that two pieces are glued together using a clear, sticky material. Laminated glass is used to protect you as well. The pieces are stuck together so that the big pieces don't get loose and fly into your face. The advantage of laminated glass is that it will hold together enough to make it so that you can still see out, so that you can hopefully have a little better chance of controlling your car.
What type of glass was used for windshields in automobiles before 1930?
Ford heard of a development in England by a company called Triplex of a laminated glass that had two pieces of glass with a plastic liner in between them. He got a patent licence on that product to introduce them, and that became the safety glass that then went around all the windows on cars.
What chemicals are used to laminate glass?
The bonding materials for glass layers in laminated glass are polyvinyl butyral or ethylene vinyl acetate.
Why plastic isn't used for windscreens?
There are windshields made of Acrylic Plastic. But especially in colder countries there is the problem of icing. While glass windshields can be provided with layers and electric currents to avoid icing. This especially applies for aeroplane windshields.
Who invented Shatter Proof glass?
The following is quoted from Wikipedia. Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. Automobile windshield with "spider web" cracking typical of laminated safety glass.Another car windshield with a spiderweb pattern, impacted by a motorcycle taillight on the highway.Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered. Skylight glazing and automobile windshields typically use laminated glass. In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior storefronts, curtainwalls and windows. The PVB interlayer also gives the glass a much higher sound insulation rating, due to the damping effect, and also blocks 99% of transmitted UV light. Laminated glass was invented in 1903 by the French chemist Edouard Benedictus, inspired by a laboratory accident. A glass flask had become coated with the plastic cellulose nitrate and when dropped shattered but did not break into pieces. Benedictus fabricated a glass-plastic composite to reduce injuries in car accidents. However, it was not immediately adopted by automobile manufacturers, and the first widespread use of laminated glass was in the eyepieces of gas masks during World War I. Today, laminated glass is produced by bonding two or more layers of ordinary annealed glass together with a plastic interlayer, usually Polyvinyl Butyral (PVB). The PVB is sandwiched by the glass which is passed through rollers to expel any air pockets and form the initial bond then heated to around 70 °C in a pressurized oil bath. The tint at the top of some car windshields is in the PVB. A typical laminated makeup would be 3 mm glass / 0.38 mm interlayer / 3 mm glass. This gives a final product that would be referred to as 6.38 laminated glass. Multiple laminates and thicker glass increases the strength. Bulletproof glass is often made of several float glass, toughened glass and Perspex panels, and can be as thick as 100 mm.

What type of glass is used for car windows?
Toughened or laminated EDIT: Laminated, annealed glass for the windshield. It will be held to gether by the plastic if broken, and not break into shards to cut the driver and passenger. The other windows are tempered, and break into small cubes that don't cut. Classic cars, like '57s chevys, have laminated glass thoughout. Antique cars , like Model T's, had simple plate glass, it caused serious cuts in an accident
Do all automobiles have UV protection on their windshield?
The best type of UV protection glass that is used for automobiles is called the laminated glass. It is made of 2 layers of glass and 1 plastic layer in the middle. It is able to filter out 95-99% of UV A and B rays. But It is usually only used in the front car window. Non-laminated glass is used for side and rear windows. They do filter most of UVB; however they allow up to 60-70% UVA to pass through. Tinting the non-laminated glass may further reduce 15-30% of UVA. You can do that with your non-laminated glass in local auto shop but just have to make sure it allow at least 70% minimum visible light transmittance through the windshield.
Why is laminated glass used for windscreens?
because it is transparent to let people see through and it does not get scratches easily so that we can see clearly
