is glass breaking a chemical change

If you’ve ever wondered whether glass breaking is a chemical change or not, you’re not alone. But fear not, dear reader, for we are here to set the record straight.

So, is glass breaking a chemical change? The answer, it turns out, is a resounding yes! When glass breaks, the bonds between the atoms that make up the glass are broken and reformed, resulting in a new substance entirely.

So there you have it! Glass breaking is


When you drop a glass and it breaks, is that a chemical change? The quick answer is no. Breaking glass is a physical change. But if you think about it, there are some chemical changes that occur when you break glass.

What is glass?

Most people think of glass as a solid, but it is actually a super-cooled liquid. That means that if you were to zoom in really close, you would see that the glass is made up of moving molecules, just like a liquid. The difference is that it takes glass a really long time to flow, so from our perspective it looks like a solid.

The chemical composition of glass

The chemical composition of glass is silicon dioxide (SiO2), which is a compound of silicon and oxygen. It is found in nature as sand. When it is heated, it melts and forms a liquid. When it cools, it forms a solid.

Glass is made by melting sand (silicon dioxide) with other ingredients such as soda ash and limestone. The molten glass is then cooled very rapidly so that it does not have time to crystallize.

When glass breaks, it shatters into small pieces. This is because the cooling process makes the glass very strong and brittle. When it breaks, the pieces are held together by the electrical forces between the molecules of SiO2.

How is glass made?

You might not think about it much, but glass is all around us. It’s in our windows, our drinking glasses, our phones—heck, even our eyeglasses. But how is glass made?

The process of making glass is actually quite simple. First, sand (also known as silicon dioxide) is heated up to 2,640 degrees Fahrenheit (1,442 degrees Celsius). This high temperature makes the sand melt and turn into a liquid.

Once the sand is liquefied, it is poured into a mold (usually made out of steel or iron). The mold gives the glass its shape. Once the glass has cooled and hardened, it is taken out of the mold and put through a furnace again to make it stronger. Finally, the glass is cut and polished to give it that smooth finish we all know and love.

The properties of glass

Glass is a non-crystalline, often transparent amorphous solid, that has widespread practical, technological, and decorative uses in, for example, window panes and glass containers (bottles and jars) for beverages, food, and some commodities. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as pitcher and Pyrex can be heated to very high temperatures in order to form them from their liquid states.

How does glass break?

There are a few different ways that glass can break. The most common is called thermal stress fracture, which happens when the glass is suddenly cooled or heated unevenly. When this happens, the inner part of the glass expands or contracts faster than the outer part, and eventually the glass will crack.

Another type of fracture is called impact fracture, which happens when something hits the glass hard enough to break it. When this happens, the force of the impact creates cracks in the glass.

Finally, there is chemical breakage, which happens when a chemical reaction causes the glass to break down. This can be caused by exposure to acid, for example.

The types of glass

There are two types of glass- Break and Non-break glass.

Breaking glass is a physical change. The change in the object’s form, appearance or texture does not change the chemical composition of the object.
Non-Break glass is a chemical change. The change in the object’s form, appearance or texture changes the chemical composition of the object.


In conclusion, yes, glass breaking is considered a chemical change because it is a permanent alteration to the glass.
