Barite (barium sulfate, BaSO 4) contains 58.8 % barium and has a specific gravity of (4.2–4.5). Commercial barite, which is usually impure, is of lower specific gravity because of the presence of other minerals such as quartz, chert, calcite, anhydrite, celestite, and various silicates.

4.6: Identifying Minerals
Specific gravity measures the weight of a mineral specimen relative to the weight of an equal volume of water. The value is expressed as a ratio between the mineral and water weights. To measure specific gravity, a mineral specimen is first weighed in grams then submerged in a graduated cylinder filled with pure water at room temperature.

Specific Gravity
Specific Gravity. The density of any material is derived by multiplying the specific gravity of that material by the density of pure water. For example, the specific gravity of barite is 4.2 and its density is equal to (4.2) (8.33 lb/gal) = 35 lb/gal. Conversely, to convert from density to specific gravity, divide the density of a material or ...

Density is defined as mass per unit volume. Specific gravity is the density of a material at a certain temperature divided by the density of water at a certain temperature. The reference temperature is usually 20°C. Density is converted to specific gravity by dividing it by the density of water at a given temperature (0.99823 g/cc at 20°C).
