Glass is a more expensive material to produce due to the complicated processes involved in its manufacture. Plastic is created by the use of oil as its base. Perhaps, in the current state of affairs and the projected events of the future this will no longer be true. But as of right now, that is why glass bottles are more expensive than plastic ones.

What kinds of capping machines are available?

Does recycling use more energy then standard waste disposal?
Yes, recycling uses more energy than trashing. It takes very little energy to throw steel, aluminium, glass, plastic and paper into a hole in the ground.But to produce more steel, aluminium, glass, plastic and paper takes vast amounts of energy. Almost twenty times as much as what it takes to recycle all these resources. And all these resources are non-renewable. When we have used them all, there's none left!So it is far cheaper to recycle and reuse.
What is the process of making laminated glass?
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
Disadvantages of glass?
Using glass as a beverage container has more disadvantages than advantages. While glass is sturdy, it is also very easily breakable and is no longer allowed in many public places, such as stadiums, for this reason.
What can empty glass bottles be made into?
They are melted down and made into more glass. Thanks
How does recycling plastic compare to recycling materials such as aluminum paper and glass?
Only aluminum is continually recyclable. Paper has a one cycle recycle life. Plastic costs more in processing and transportation costs than the plastic resins are worth. Household pay more to recycle plastic than it would cost to bury it. Glass is not cost effective to recycle because it costs more to clean and separate it than it costs to make new glass. The energy to make new glass is about the same as recycling used glass.
What is more durable plastic or glass?
Glass is more durable.
Do plastic Slinkys cost less the metal ones?
yes they our since metal costs more to make then plastic. Plastic slinkies cost about $4
Would glass or plastic shelving be better in a freezer and can you explain your choice?
Plastic shelving would be better in a freezer than glass because the extreme cold would make the glass more brittle and thus more likely to break.
Does plastic or glass weigh more?
Glass is generally heavier than plastic. This is because glass is denser and more solid compared to plastic, which is lighter and more flexible.
Why do you use glass and not plastic to make windows?
Glass is more durable than plastic. Plastic is a porous material, which means with absorbs moisture and contaminants. Plastic will also deteriorate when exposed to sunlight. Basically a plastic window would turn yellow and become brittle after only a few years, where a glass window will remain clear and strong for a very long time.
Which is more better to use a glass thermometer or a plastic thermometer?
There is no difference in the effectiveness of glass or plastic. Glass is more fragile for breaking but easier to keep clean, plastic is safer for not breaking, and harder to keep clean longer. It is a personal choice.
Which is easier to recycle glass or plastic?
Yes, both glass and plastic bottles can be recycled, although which kinds of plastic depends on the recycling program in your area. Check out this article for more information: http://kansascity.about.com/od/communityinformation/p/RecycleKC.htm.
Can plastic cup be replaced by glass beaker in determination of heat of solution?
Yes, a glass beaker can typically be used as a substitute for a plastic cup in the determination of heat of solution. Glass is generally a better material as it is more chemically inert and can withstand higher temperatures than plastic, making it more suitable for certain experiments involving heat. Make sure to check that the glass beaker is heat-resistant and appropriate for the experiment.
Which gets hotter paper or plastic or glass in the sun?
Plastic heats up the most in the sun, followed by glass and then paper. Plastic absorbs and retains heat more efficiently than glass or paper due to its composition. Glass and paper reflect more sunlight and are better insulators, which helps keep them cooler than plastic.
Why is a glass jug better than a plastic jug when measuring water?
Water "wets" plastic more than glass, giving a lower reading
What are the relative merits of plastic and glass for lenses?
The advantage of plastic is that it is lightweight and more impact resistant than glass. The advantage of glass is that it is scratch resistant and provides the clearest possible vision.
