The most commonly used form of glass, which you’ll find in everything from windows to drinking glasses, is technically known as soda lime silicate glass. Manufacturing this common material requires furnaces that get up to 1,500 °C (2,732 °F), which of course consumes a lot of energy and releases a huge amount of carbon dioxide into the atmosphere. On top of that, this glass is made from quartz sand, soda ash and limestone, the latter two of which release CO2 when melted.
Now, Penn State researchers have improved the recipe to make glass that’s more environmentally friendly to produce, while also being much stronger.
