Density of Glass

[blueleg]

Does anyone know the density of the glass used in aquariums? I am modeling a couple set-ups for a paper.

Thanks in advance,

It probably varies based on the type of glass

It probably varies based on the type of glass, but blindmelonbob is correct, its gotta be greater then 1 or else it would float!

Silicone glass, tempered glass, and other glasses used in aquariums are nearly identical in their densities. In SI units the density of glass is 2270 kg/m^3. In english units it is 141.6 lbs/ft^3 or 0.08201 lb/in^3.

You only get significant variations in densities when you go to crystal which can be made from a wide variety of elements. Most commonly, it is made with lead and is very dense but that is not used in aquariums due to the cost.

Ummmm....Greater than 1 what? Density is measured in units of weight or mass over volume


I think you are confusing density with specific gravity which is a comparison of the density of a given material to the density of pure water.

2400 g/cm3 is a good number to use.

thanks guys
