Specific Gravity of Minerals - Ohio History Central

Dry weight divided by loss equals : 4.5. In fact, the of barite varies between 4.3 and 4.6. This results in part from impurities that may be present in varying quantities in different specimens of this . Most have variable gravities. In some the variation may be as much as 25%.

    The - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C 39 o F as reference - at this point the density of water is at the highest.. gravities - SG - for common solids and metals can be found in the table below:
