# ASTM C693

Standard Test Method for Density of Glass by Buoyancy

[Back to all techniques](/analytical-techniques/)

## Significance and Use

4.1 Density as a fundamental property of glass has basic significance. It is useful in the physical description of the glass and as essential data for research, development, engineering, and production.

## Scope

1.1 This test method covers the determination of the density of glasses at or near 25 °C, by buoyancy.
