Do know facts about glass? Glass is an object that is familiar with everyday life and can be found in almost all aspects of human life such as glass doors and windows, glass sculptures, artistic homes and most hotels made of glass.
Do you believe that glass is made of liquid sand? This is true and the fact about glass, you can even make your own glass by heating the ordinary sand that you find on the beach so that it melts and turns into a liquid, which is partly made of silicon dioxide sand. The sand will change form to liquid at very high temperatures up to 1700 ° C (3090 ° F).
So, what is glass actually made of? Yes, glass is a condensed non-crystalline amorphous form with a transparent form, as well as a very practical and decorative use, widely used by humans. In addition, glass is the object most often formed by a cooling process that does not take long from a liquid form. Moreover, some glasses such as volcanic glass is formed and occurs naturally.
In this article, we will discuss more deeply about interesting facts about glass.
Let’s see how the glass is made
In 1945, an American scientist was testing the performance of an atomic bomb in the New Mexico desert, the explosion caused the sand in the desert to change shape to glass. However, there is the easiest and less extreme way to make glass, but the main requirement is to use very high heat.
If you look at several commercial glass factories, it is found that sand is usually mixed with waste glass, this is a recycling process, by mixing chemicals such as soda ash (sodium carbonate) with limestone (calcium carbonate) which is then put into a furnace. in very high heat. Soda (sodium carbonate) functions to reduce the melting point of sand, and also helps in saving energy during the manufacturing process, at the same time limestone is added to help melt excess sand until at the end of the manufacturing process it is called lime-silica soda glass, the finished result glass that is often found in everyday life.
When the sand succeeds in melting at high heat, then it is poured into a mold that is adjusted to your liking, for example in the form of bottles, glasses, or in other containers, it can even be poured into large molten tin metal to make sheets of glass where this has a flat surface to use as window glass.
The use of glass in the past
In ancient times, Obsidian-shaped glass was used in prehistoric times when humans used weapons in the form of spears. There is some other evidence that says that the first piece of glass was made by humans in around 3000 BC where the center of glass making, detected in history, in Egypt and Mesopotamia, this is a famous glass making place. In addition, glass containers were made around 1500 BC. This is the interesting facts about glass you might not know.
Is glass considered liquid or solid?
This is a very interesting question. Most people think of glass as a liquid, but it is also considered a solid object. There is a lot of scientific evidence that points to the second answer, a lot of disagreements about how glass looks like a liquid and also looks like a solid in some ways.
The answer is both – and not both! There are many disagreements about how to refer to glass-like materials that appear to be liquid in some ways and somewhat similar to solids in some. According to scientific references studied in school, solid objects have a permanent atomic structure.
Unique properties that forms Glass
Do you know that glass consists of unique particles that are not owned by other objects? As many people know that this object is transparent, translucent, and looks clear and clear, and has a smooth surface. In addition, glass is also resistant to erosion and can also reflect and refract light, there are many other properties of this object. Moreover, glass is also resistant to other chemicals, this is why glass is also used in a number of laboratories and hospitals, especially glass in the form of glass.
Have you ever noticed that some glasses are colorful? Yes, you might have seen them quite often in your daily life. Most people know that glass is transparent. Thus, do you know where the colored glass came from? This is one of the amazing facts about glass. According to the glassmakers at the glass factory, they used a mixture of various metal oxides and mixed with alkaline sulfides to get colored glass. Moreover, they even mix it with electrically made ions into it to get colorful glass for example chemicals like cupric oxide will give a turquoise tinted glass effect, while manganese dioxide will produce glass with purple color and so on. Pretty interesting, right?
Fiber optics are made of glasses
You might have heard of fiber optics, which are used mostly in telecommunications in all parts of the world. However, did you know that fiber optics are made of glass? Yes, these optical fibers are mostly made of glass and some are made of plastic or polymer. Optical fibers made of glass can transfer data at speeds of up to 10 Gbps.
When glasses are shattered into a thousand tiny pieces
Apart from different assumptions about whether glass is liquid or solid, basically glass is an object that is easily broken into pieces. Do you know how fast the shattered glass is? It is an interesting fact that the broken glass moves at an incredible speed of up to about 3000 miles per hour or about 4,828 kilometers per hour. You can imagine and compare it with the speed of sound in the air which reaches about 767 miles per hour. That looks wonderful, doesn’t it?
That’s a glimpse of extraordinary facts about glass, an object that is often found every day and provides many benefits, especially in functionality and aesthetic aspects of human life.
