We have choosen an object, which we use every day and we actually don’t know a lot about it. So we decided to take the mirror, because every morning in the bathroom or when we drive by car, we need the mirror. For us, the mirror is that normal, that we’re no longer perceiving (wahrnehmen) it.
With our project, we would like to show people how a mirror is made, how to use it and what happens when the mirror is broken.
With this project we want to make people think about the mirror, when they look in it.
The first mirrors of the people consisted of still water. The only requirement was a very smooth surface. The earliest manufactured mirrors were pieces of polished stone such as obsidian, a naturally occurring volcanic glass.
Later, glass was a desirable material for mirrors. Because the surface is very smooth, it creates a reflection. In addition, glass is hard and scratch-resistant. However, glass by itself has little reflectivity, so people began coating it with metals to increase the reflectivity. 
For the production, the manufactures use ordinary glass, as everyone knows it.
However, there are some companies which produce the glass itself in order to be able to produce a high-quality mirror.
2. Break glass
The glass is broken by hand in the right size, because the step needs a lot of fingertip feeling.
If the glass has the correct size, it is cleaned with distilled water so that the following layer of silver is adhered. The use of distilled water and not ordinary water is important because it does not contain any ions, such as lime (Kalk), which can leave residues and destroy the silver layer applied afterwards.
Then, the glass plate is polished with cerium oxide to ensure that the glass is mirror-finished.
5. Layer of silver
The next step is for the first time a reflection of the creation of a mirror. A thin layer of silver is applied to the glass, which should reflect the mirror image perfectly at the end. Mirroring can be done already, but a few steps are still missing until the mirror is completely ready for use.
6. Protective layer
Because silver has the property of easily corroding, a protective lacquer must be applied to the silver layer as soon as it is dry. If this did not happen, black spots would appear and the mirror would no longer be used.
To ensure that the manufacturers are on the safe side, a lacquer is applied after the protective lacquer, which protects against corrosion and scratches.
The mirror is then dried at 200 degrees for about three minutes.
9. Grind and clean
When the mirror is dried, the sharp edges are ground and the glass plate is cleaned again, so that the mirror can be sold without errors and cleanly polished.
10. Last check
Before the final sale, however, the mirror is again controlled by the human eye. In this way, possible impurities can be determined which a machine would not recognize.
11. Ready for sale
Now the mirror is packaged in a shatter-proof way and goes on the journey to various dealers. 
A mirror can be used in different ways, for example in the bathroom to brush your teeth, in a car to look for your and others safety, but also for other things, like for a mirror house. In the following video you can see how it looks like in a mirror house.

End of life
If your mirror breaks you can not throw it into the normal trash and also not into the bottle bank but why?
Mirror are made out of another glass than a normal glass bottle, so you’re not allowed to put it into the same bank. Mirror glass is called plate glass. This is a glass which can’t get recycled like others. If we still throw it into the bottle bank, it’s hard to select it out.
So where I have to dispose a mirror?
If the mirror brakes down into a lot of pieces you can throw it into the residual waste container (Restmülltonne).
If the mirror is complete you have 3 options:
1. You can break it down into small pieces and then throw it into the residual waste.
2. You make an appointment with the bulky waste (Sperrmüll) center and dispose it there.
3. You can bring it to a buyback centre (Wertstoffsammlung).
We found it very exciting to write about a topic, which we use each day and then publish on a homepage. This was the first time that I had worked on a homepage.
The work was very strict but you could also see a result in the end. For the next time we learned that the plan is very important, to know when and how you want to do something. We are satisfied with the development, but it would have been nice if we had been able to visit a company which produces mirrors. But all in all we are satisfied.
We hope that we as a whole group, which has edited the website, are able to show people something exciting and put something new on the way in life.
