How is glass made?

Glass is made from sand! First, sand is heated up until it melts into a liquid. Then, the liquid is cooled down quickly so it becomes solid again. This solid glass can be made into different shapes, like windows and bottles.

Glass is made from sand, soda ash, and limestone. Sand is melted at very high temperatures until it forms a liquid. Soda ash and limestone are added to the melted sand to help the glass become stronger and more durable. When the mixture cools, it turns into glass that can be used for many things, like windows, bottles, and jewelry!

Glass is made from sand, soda ash, and limestone. First, the sand is melted in a furnace at very high temperatures (up to 3,000 degrees Fahrenheit!). This melted sand, called "molten glass," is then shaped into the desired form. Soda ash and limestone are added to the molten glass to make it stronger. Finally, the glass is cooled and hardened. That's how glass is made!
