What is the density of glass?

The density of most glass ranges between 2.4 g/cm³ to 2.8 g/cm³. The density of window glass is between 2.47 g/cm³ and 2.56 g/cm³. The glass in a vehicle headlight falls with the range of 2.47 g/cm³ and 2.63 g/cm³.

Soda-lime glass is the most common type of glass and it is usually what is being referred to when the term "glass" is used. In addition to several types of additives, soda-lime glass is made from lime (CaO), sodium oxide (Na₂O) from sodium carbonate (Na₂O₃), and silicon dioxide (SiO₂), also known as silica and the most common fundamental component in glass. Silica can account for up to about 75 percent of glass by weight.
