What Temperature Does a Beer Bottle Melt At?
A beer bottle will melt at around 1832 degrees Fahrenheit, or 1000 degrees Celsius. Beer bottles, like glass jars and most other commercial glass containers, are made from soda-lime glass, which melts at around half the temperature of sand.
Soda-lime glass is a combination of 60-75 percent silica sand (silicon dioxide, SiO2), 12-15 percent soda ash (sodium carbonate, Na2CO3) and 5-12 percent limestone or dolomite (calcium carbonate, CaCO3). Small quantities of other materials are also added for specific purposes, such as color.
Whereas soda gives the glass its comparatively low melting point, which makes it well-suited to recycling, it also lowers its durability. Meanwhile, lime acts as a stabilizer to increase the hardness and durability.
